CVE-2019-3568
Buffer Overflow RCE in WhatsApp VoIP Stack via Crafted RTCP Packets

A buffer overflow (CWE-122) in the VoIP telephony stack of WhatsApp allowed a remote attacker to achieve remote code execution on a target device by sending a specially crafted series of RTCP packets to the victim's phone number. Because the flaw resided in the call-handling stack of the core app, an attacker who could reach the target's phone number over the network could gain arbitrary code execution on the device. All WhatsApp users at the time of disclosure were potentially exposed, since the vulnerable component shipped in the mainstream Meta Platforms (then Facebook) product rather than an optional add-on. The vulnerability was added to CISA's Known Exploited Vulnerability catalog on 2022-04-19, indicating confirmed real-world exploitation, and its EPSS score of 39.2% (99th percentile) signals a high likelihood of continued exploitation; no public proof-of-concept is known. It was remediated in vendor updates issued in 2019 and is widely associated with targeted espionage use (notably Pegasus spyware deployments).

Do: Update WhatsApp on all mobile devices to the latest vendor release, per the CISA KEV required action; inventory your mobile fleet for outdated 2019-era builds and verify current app versions. Prioritize high-value targets (executives, journalists, government personnel) given the vulnerability's confirmed in-the-wild exploitation in espionage campaigns. No public PoC is known, but the flaw is remotely exploitable via network packets to a phone number, so treat patching as urgent.

CVE-2024-12856
OS Command Injection in Four-Faith F3x24/F3x36 Routers

Four-Faith industrial router models F3x24 and F3x36 running firmware version 2.0 are vulnerable to OS command injection (CWE-78) through the apply.cgi interface when an attacker modifies the system time over HTTP. The flaw is technically authenticated (CVSS 3.1: 7.2, network-adjacent-remote with high privileges required), but the same firmware ships with default credentials, so any device where defaults were not changed is effectively exposed to unauthenticated remote OS command execution. A successful attacker can run arbitrary commands on the router, gaining full device compromise that can be used for further access or recruitment into botnets. Four-Faith deployments — typically industrial and remote-connectivity routers — are affected, with at least 15,000 routers exposed to the internet and many retaining default credentials. Exploitation is confirmed in the wild: a Mirai botnet variant has weaponized the flaw for DDoS attacks, and the RondoDox botnet is also targeting it, consistent with a high EPSS score (84.2% probability of exploitation within 30 days, 100th percentile).

Do: Update F3x24/F3x36 devices to the latest firmware available from Four-Faith and verify apply.cgi handling is fixed; as an immediate mitigation, change default administrator credentials and restrict HTTP management access to trusted networks. Check devices for signs of botnet infection (unexpected outbound traffic or Crontab/persistence changes) and prioritize patching given confirmed in-the-wild exploitation by Mirai and RondoDox botnets.

7.284% PoC ×2
  • Four-Faith F3x24 router firmware at least firmware version 2.0 (exact affected version range not specified in the data)

large≈15,000+ internet-exposed routers (headline scan count; total deployments likely higher)
CVE-2024-3393
Unauthenticated Remote DoS via DNS Packet Parsing in Palo Alto Networks PAN-OS

Palo Alto Networks PAN-OS contains a flaw (CWE-754) in how the DNS Security feature parses and logs malicious DNS packets, which an unauthenticated remote attacker can abuse by sending crafted DNS traffic to a firewall with the feature enabled. Successful exploitation triggers a remote reboot of the firewall, and repeated exploitation attempts can push the device into maintenance mode, causing a sustained denial of service until an administrator intervenes. Only PAN-OS deployments that use the DNS Security feature are affected; the attacker requires no credentials, only network reachability to traffic inspected by the firewall. The flaw was added to the CISA KEV catalog on 2024-12-30, indicating confirmed in-the-wild exploitation, and its EPSS score of 28.4% (98th percentile) signals elevated exploitation risk, though no public proof-of-concept code is known and CVSS scoring is not yet available.

Do: Check the Palo Alto Networks advisory for this CVE to determine whether your PAN-OS release with DNS Security enabled is affected, and upgrade to the recommended fixed hotfix release per vendor instructions; if mitigations are unavailable, CISA's KEV guidance is to discontinue use of the affected product. Limit exposure of firewall interfaces and DNS Security processing paths to untrusted DNS traffic, and monitor devices for unexplained reboots or entry into maintenance mode, which would indicate exploitation attempts.

8.728% KEV
  • Palo Alto Networks PAN-OS
largetens of thousands of PAN-OS firewalls plausibly affected (roughly 10k-100k systems, limited to devices with DNS Security enabled)
CVE-2024-43441
Authentication Bypass in Apache HugeGraph-Server (CVE-2024-43441)

CVE-2024-43441 is a critical (CVSS 9.8) authentication-bypass flaw (CWE-302, Authentication Bypass by Assumed-Immutable Data) in Apache HugeGraph-Server, where the server validates access based on request data it assumes cannot be modified. A remote attacker with network access can send specially crafted requests that tamper with this assumed-immutable data (such as credential/token material supplied in the request), slipping past the authentication layer of the server's API without any valid credentials. The flaw requires no privileges and no user interaction, and once past authentication the attacker gains the access of a legitimate user, with high impact on confidentiality, integrity, and availability of the graph data (CVSS C:H/I:H/A:H). All HugeGraph-Server deployments running version 1.0.0 or later but earlier than 1.5.0 are affected; the flaw is most consequential where authentication was deliberately enabled, since it renders that protection ineffective. No public proof-of-concept or confirmed in-the-wild exploitation is known yet, but the EPSS score of 69.4% (99th percentile) indicates a high likelihood of exploitation within 30 days, so this should be treated as urgent to patch.

Do: Upgrade Apache HugeGraph-Server to version 1.5.0, which fixes the issue. Until patched, do not rely on authentication to protect exposed instances: locate any HugeGraph-Server reachable from untrusted networks (REST/Gremlin API, by default on port 8080) and restrict access with firewall rules or a reverse proxy. Given the 69.4% EPSS score, review server logs for unexpected unauthenticated API access and watch for follow-on PoC or exploitation reports.

CVE-2024-45387
Authenticated SQL Injection in Apache Traffic Control Traffic Ops

CVE-2024-45387 is an SQL injection flaw in Traffic Ops, the API component of the Apache Traffic Control CDN management platform, affecting version 8.0.0 per the Apache advisory. It is triggered when a user who already holds one of the "admin", "federation", "operations", "portal", or "steering" roles sends a specially crafted PUT request to the Traffic Ops API. Successful injection lets the attacker execute arbitrary SQL against the Traffic Ops database, allowing them to read, modify, or corrupt stored data, consistent with the high confidentiality, integrity, and availability ratings in the 8.8 CVSS score. Any operator running an affected Traffic Ops deployment is exposed, though exploitation requires an authenticated privileged account. No public proof-of-concept or confirmed in-the-wild exploitation is known yet, but EPSS places this flaw in the 99th percentile with roughly a 41.5% probability of exploitation within 30 days, so patching is urgent.

Do: Upgrade Traffic Ops to Apache Traffic Control 8.0.2 or later as recommended by the advisory. In the meantime, restrict API access to trusted networks and review accounts holding the admin, federation, operations, portal, and steering roles, since any of them can trigger the injection via crafted PUT requests. Check Traffic Ops and database logs for unexpected or anomalous SQL from API activity, and watch for public exploits given the elevated EPSS score.

CVE-2024-52046
Unauthenticated RCE in Apache MINA via Insecure Java Deserialization

Apache MINA's ObjectSerializationDecoder processes incoming data using Java's native deserialization protocol without the necessary security checks or defenses (CWE-502), and the flaw carries a maximum CVSS 4.0 score of 10.0. An attacker who can send data to a service using this decoder can deliver a specially crafted serialized object that is reconstructed without validation, leading to remote code execution with no privileges, user interaction, or attack prerequisites required. Exploitation is conditional: only applications that call IoBuffer#getObject(), typically when a ProtocolCodecFilter built with ObjectSerializationCodecFactory is added to the filter chain, are affected, and the FtpServer, SSHd, and Vysper sub-projects are explicitly not impacted. All MINA core 2.0.X, 2.1.X, and 2.2.X releases prior to 2.0.27, 2.1.10, and 2.2.4 respectively are affected. No public proof-of-concept or confirmed in-the-wild exploitation is known and the flaw is not in CISA's KEV, but EPSS assigns a 23.9% probability of exploitation within 30 days (98th percentile), indicating elevated risk.

Do: Upgrade MINA core to 2.0.27, 2.1.10, or 2.2.4 depending on which 2.x line you run. After upgrading, explicitly allow the classes your protocol needs on the ObjectSerializationDecoder using the new accept(ClassNameMatcher), accept(Pattern), or accept(String...) methods, since the default now rejects all incoming classes. Audit your filter chain for ObjectSerializationCodecFactory usage or any IoBuffer#getObject() call to confirm whether you are exposed; FtpServer, SSHd, and Vysper deployments are not affected.

10.024%
  • Apache MINA core all 2.0.X releases prior to 2.0.27

CVE-2024-56337
Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat.

Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. The mitigation for CVE-2024-50379 was incomplete. Users running Tomcat on a case insensitive file system with the default servlet write enabled (readonly initialisation parameter set to the non-default value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which version of Java they are using with Tomcat: - running on Java 8 or Java 11: the system property sun.io.useCanonCaches must be explicitly set to false (it defaults to true) - running on Java 17: the system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false) - running on Java 21 onwards: no further configuration is required (the system property and the problematic cache have been removed) Tomcat 11.0.3, 10.1.35 and 9.0.99 onwards will include checks that sun.io.useCanonCaches is set appropriately before allowing the default servlet to be write enabled on a case insensitive file system. Tomcat will also set sun.io.useCanonCaches to false by default where it can.

Palo Alto Networks PAN-OS Flaw Under Attack — Palo Alto Networks has disclosed a high-severity flaw impacting PAN-OS software that could cause a denial-of-service (DoS) condition on susceptible devices by sending a specially crafted DNS packet. The vulnerability (CVE-2024-3393, CVSS score: 8.7) only affects firewalls that have the DNS Security logging enabled. The company said it's aware of "customers experiencing this denial-of-service (DoS) when their firewall blocks malicious DNS packets that trigger this issue."

🔔 Top News

  • Contagious Interview Drops OtterCookie Malware — North Korean threat actors behind the ongoing Contagious Interview campaign have been observed dropping a new JavaScript malware called OtterCookie. The malware, likely introduced in September 2024, is designed to establish communications with a command-and-control (C2) server using the Socket.IO JavaScript library, and awaits further instructions. It's designed to run shell commands that facilitate data theft, including files, clipboard content, and cryptocurrency wallet keys.
  • Cloud Atlas Continues its Assault on Russia — Cloud Atlas, a hacking of unknown origin that has extensively targeted Russia and Belarus, has been observed using a previously undocumented malware called VBCloud as part of its cyber attack campaigns targeting "several dozen users" in 2024. The attacks employ phishing emails containing Microsoft Word documents, which, when opened, trigger an exploit for a seven-year-old security flaw to deliver the malware. VBCloud is capable of harvesting files matching several extensions and information about the system. More than 80% of the targets were located in Russia. A lesser number of victims have been recorded in Belarus, Canada, Moldova, Israel, Kyrgyzstan, Turkey, and Vietnam.
  • Malicious Python Packages Exfiltrate Sensitive Data — Two malicious Python packages, named zebo and cometlogger, have been found to incorporate features to exfiltrate a wide range of sensitive information from compromised hosts. Both the packages were downloaded 118 and 164 times each, before they were taken down. A majority of these downloads came from the United States, China, Russia, and India.
  • TraderTraitor Behind DMM Bitcoin Crypto Heist — Japanese and U.S. authorities officially blamed a North Korean threat cluster codenamed TraderTraitor (aka Jade Sleet, UNC4899, and Slow Pisces) for the theft of cryptocurrency worth $308 million from cryptocurrency company DMM Bitcoin in May 2024. The attack is notable for the fact that the adversary first compromised a system belonging to an employee of Japan-based cryptocurrency wallet software company Ginco under the pretext of a pre-employment test. "In late-May 2024, the actors likely used this access to manipulate a legitimate transaction request by a DMM employee, resulting in the loss of 4,502.9 BTC, worth $308 million at the time of the attack," authorities said.
  • WhatsApp Scores Legal Victory Against NSO Group — NSO Group has been found liable in the United States after a federal judge in the state of California ruled in favor of WhatsApp, calling out the Israeli commercial spyware vendor for exploiting a security vulnerability in the messaging app to deliver Pegasus using WhatsApp's servers 43 times in May 2019. The targeted attacks deployed the spyware on 1,400 devices globally by making use of a then zero-day vulnerability in the app's voice calling feature (CVE-2019-3568, CVSS score: 9.8).

📰 Around the Cyber World

  • ScreenConnect Used to Deploy AsyncRAT — Microsoft has revealed that cybercriminals are leveraging tech support scams to deploy AsyncRAT through the remote monitoring and management (RMM) software ScreenConnect, the first time that ScreenConnect is used to deploy malware, instead of as a persistence or lateral movement tool. The company also said threat actors are using SEO poisoning and typosquatting to deploy SectopRAT, an infostealer used to target browser information and crypto wallets. The disclosure comes as Malwarebytes disclosed that criminals are employing decoy landing pages, also called "white pages," that utilize AI-generated content and are propagated via bogus Google search ads. The scam involves attackers buying Google Search ads and using AI to create harmless pages with unique content. The goal is to use these decoy ads to then lure visitors to phishing sites for stealing credentials and other sensitive data. Malvertising lures have also been used to distribute SocGholish malware by disguising the phishing page as an HR portal for a legitimate company named Kaiser Permanente.
  • AT&T, Verizon Acknowledge Salt Typhoon Attacks — U.S. telecom giants AT&T and Verizon acknowledged that they had been hit by the China-linked Salt Typhoon hacking group, a month after T-Mobile made a similar disclosure. Both the companies said they don't detect any malicious activity at this point, and that the attacks singled out a "small number of individuals of foreign intelligence interest." The breaches occurred in large part due to the affected companies failing to implement rudimentary cybersecurity measures, the White House said. The exact scope of the attack campaign still remains unclear, although the U.S. government revealed that a ninth telecom company in the country was also a target of what now appears to be a sprawling hacking operation aimed at U.S. critical infrastructure. Its name was not disclosed. China has denied any involvement in the attacks.
  • Pro-Russian Hacker Group Targets Italian Websites — Around ten official websites in Italy were targeted by a pro-Russian hacker group named Noname057(16). The group claimed responsibility for the distributed denial-of-service (DDoS) attacks on Telegram, stating Italy's "Russophobes get a well deserved cyber response." Back in July, three members of the group were arrested for alleged cyber attacks against Spain and other NATO countries. Noname057(16) is one of the many hacktivist groups that have emerged in response to the ongoing conflicts in Ukraine and the Middle East, with groups aligned on both sides engaging in disruptive attacks to achieve social or political goals. Some of these groups are also state-sponsored, posing a significant threat to cybersecurity and national security. According to a recent analysis by cybersecurity company Trellix, it's suspected that there's some kind of an operational relationship between Noname057(16) and CyberArmyofRussia_Reborn, another Russian-aligned hacktivist group active since 2022. "The group has created alliances with many other hacktivist groups to support their efforts with the DDoS attacks," Trellix said. "However, the fact that one of the previous CARR administrators, 'MotherOfBears,' has joined NoName057(16), the continuous forwarding of CARR posts, and previous statements, suggest that both groups seem to collaborate closely, which can also indicate a cooperation with Sandworm Team."
  • UN Approves New Cybercrime Treaty to Tackle Digital Threats — The United Nations General Assembly formally adopted a new cybercrime convention, called the United Nations Convention against Cybercrime, that's aimed at bolstering international cooperation to combat transnational threats.. "The new Convention against Cybercrime will enable faster, better-coordinated, and more effective responses, making both digital and physical worlds safer," the UN said. "The Convention focuses on frameworks for accessing and exchanging electronic evidence, facilitating investigations and prosecutions." INTERPOL Secretary General Valdecy Urquiza said the UN cybercrime convention "provides a basis for a new cross-sector level of international cooperation" necessary to combat the borderless nature of cybercrime.
  • WDAC as a Way to Impair Security Defenses — Cybersecurity researchers have devised a new attack technique that leverages a malicious Windows Defender Application Control (WDAC) policy to block security solutions such as Endpoint Detection and Response (EDR) sensors following a system reboot. "It makes use of a specially crafted WDAC policy to stop defensive solutions across endpoints and could allow adversaries to easily pivot to new hosts without the burden of security solutions such as EDR," researchers Jonathan Beierle and Logan Goins said. "At a larger scale, if an adversary is able to write Group Policy Objects (GPOs), then they would be able to distribute this policy throughout the domain and systematically stop most, if not all, security solutions on all endpoints in the domain, potentially allowing for the deployment of post-exploitation tooling and/or ransomware."

🔒 Tip of the Week

Isolate Risky Apps with Separate Spaces — When you need to use a mobile app but aren’t sure if it’s safe, protect your personal data by running the app in a separate space on your phone. For Android users, go to Settings > Users & Accounts and create a Guest or new user profile.

Install the uncertain app within this isolated profile and restrict its permissions, such as disabling access to contacts or locations. iPhone users can use Guided Access by navigating to Settings > Accessibility > Guided Access to limit what the app can do. This isolation ensures that even if the app contains malware, it cannot access your main data or other apps.

If the app behaves suspiciously, you can easily remove it from the separate space without affecting your primary profile. By isolating apps you’re unsure about, you add an extra layer of security to your device, keeping your personal information safe while still allowing you to use the necessary tools.

Conclusion

This week’s cybersecurity updates highlight the importance of staying vigilant and prepared. Here are some simple steps to keep your digital world secure:

  • Update Regularly: Always keep your software and devices up-to-date to patch security gaps.
  • Educate Your Team: Teach everyone to recognize phishing emails and other common scams.
  • Use Strong Passwords: Create unique, strong passwords and enable two-factor authentication where possible.
  • Limit Access: Ensure only authorized people can access sensitive information.
