Fortinet researchers documented Evooo1Bot, a new Mirai-derived Linux botnet active since July 2026 that exploits known edge-device flaws to build SOCKS5 proxy networks.
Fortinet FortiGuard Labs identified Evooo1Bot, a previously undocumented Linux botnet built on the leaked Mirai source code, active in the wild since July 2026 and targeting internet-facing edge devices. It exploits numerous known CVEs in routers and devices from D-Link, Tenda, Telesquare, Zyxel, Hikvision, Atlassian Confluence, WSO2, TP-Link, NETGEAR, and others, delivering a bot binary via a wget.sh loader from 91.92.40.118 that clears bash history. The bot offers encrypted C2 on port 443, SSH brute-force scanning, credential sniffing, DDoS over DNS/TCP/UDP, an HTTP exploit dispatcher, and converts infected hosts into SOCKS5 proxies for anonymizing follow-on operations.
Unauthenticated Command Injection in Tenda AC7, AC9, and AC10 Routers
CVE-2018-14558 is an unauthenticated OS command injection flaw (CWE-78) in the web interface of Tenda AC7, AC9, and AC10 routers, where the formsetUsbUnload handler passes untrusted input to the dosystemCmd function. An attacker triggers it by sending a crafted HTTP request to the goform/setUsbUnload endpoint, requiring no authentication or user interaction per the CVSS vector (AV:N/AC:L/PR:N/UI:N). Successful exploitation yields arbitrary command execution on the router, enabling full device takeover for traffic interception, botnet enrollment, or pivoting into the local network. Anyone running AC7 firmware through V15.03.06.44_CN(AC7), AC9 firmware through V15.03.05.19(6318)_CN(AC9), or AC10 firmware through V15.03.06.23_CN(AC10) is affected. The flaw has a public proof of concept, an 8.7% EPSS (95th percentile), and was added to CISA's Known Exploited Vulnerabilities catalog on 2021-11-03, indicating exploitation in the wild.

Unrestricted file upload leading to unauthenticated RCE in multiple WSO2 products
CVE-2022-29464 is an unrestricted file upload flaw (CISA classifies it as CWE-22, path traversal) in multiple WSO2 products — including WSO2 API Manager, Identity Server (and its Analytics and as-Key-Manager variants), and Enterprise Integrator — that lets an attacker write arbitrary files, such as JSP webshells, to any location on the server. It is triggered by sending crafted multipart upload requests to the WSO2 Carbon management-console file-upload endpoints, where directory traversal in the upload path allows files to be planted in the web root; requesting the uploaded file then executes it as code. An attacker who can reach a vulnerable management console gains unauthenticated remote code execution with the privileges of the WSO2 server process, which is often root in containerized deployments, enabling webshells, lateral movement, and ransomware staging. Any organization running affected WSO2 releases is exposed, especially where Identity Server (SSO/IAM) or API Manager gateways are internet-facing; the exact affected version ranges are enumerated in the WSO2 vendor advisory. Exploitation is confirmed: CISA added the flaw to the KEV catalog on 2022-04-25 with known ransomware use, and EPSS assigns a roughly 100% probability of exploitation within 30 days, making patching urgent.
Unauthenticated OS Command Injection in Tenda AC15 AC1900 Router
CVE-2020-10987 is an unauthenticated OS command injection flaw (CWE-78) in the goform/setUsbUnload endpoint of the Tenda AC15 AC1900 router, demonstrated on firmware version 15.03.05.19. An attacker triggers it by sending a crafted deviceName POST parameter to that endpoint, which is not properly sanitized before being used in a system command. Successful exploitation yields arbitrary remote code execution on the router, giving the attacker full control of the device and a foothold to pivot into the local network, as is typical for IoT botnet recruitment. Owners of Tenda AC15 routers are affected, with greatest risk on units whose web administration interface is reachable from the internet. Exploitation is confirmed in the wild: the flaw is in CISA's Known Exploited Vulnerabilities catalog (added 2021-11-03), carries a 79.8% EPSS score (top percentile), and a public proof of concept has been available since its 2020 disclosure; ransomware use is unknown.

Unauthenticated Buffer Overflow in D-Link GO-RT-AC750 Router Firmware
CVE-2022-37055 is a buffer overflow (CWE-120) in the cgibin binary's hnap_main handler on D-Link GO-RT-AC750 routers running GORTAC750_revA_v101b03 or GO-RT-AC750_revB_FWv200b02 firmware. Because the flaw sits in the router's HNAP/web management interface and requires no authentication, a remote attacker can trigger it with crafted network requests sent directly to the device. Successful exploitation can corrupt memory and is scored critical (CVSS 3.1: 9.8), giving the attacker potential full control of the router with high confidentiality, integrity, and availability impact. Owners of these specific GO-RT-AC750 (rev A and rev B) firmware releases are affected, and the broader context of active Mirai-family botnet campaigns targeting Linux-based edge devices raises the risk of automated mass exploitation. CISA added the vulnerability to the Known Exploited Vulnerabilities catalog on 2025-12-08, confirming exploitation in the wild, and its EPSS of 55.5% (99th percentile) indicates a high near-term probability of exploitation.

OS Command Injection in Windows PHP-CGI Allows Remote Code Execution
CVE-2024-4577 is an OS command injection flaw (CWE-78) in Windows-based PHP when it runs in CGI mode, allowing arbitrary code execution on the server. It is triggered when attacker-supplied characters in HTTP requests are mishandled by Windows' character-encoding conversion as the OS invokes php-cgi, letting attackers inject command-line arguments to the PHP interpreter; this bypasses the decade-old fix for CVE-2012-1823. A successful attacker gains the ability to run arbitrary commands and code in the context of the web server. Affected systems are PHP running on Windows through the CGI interface; deployments that do not use PHP-CGI on Windows are not described as affected in the source data. Exploitation is active: the flaw was added to CISA KEV on 2024-06-12 with known ransomware use, and EPSS assigns roughly 100% probability of exploitation within 30 days.
Unauthenticated OGNL Injection RCE in Atlassian Confluence Server/Data Center
Atlassian Confluence Server and Data Center contain an unauthenticated remote code execution flaw caused by improper neutralization of expression-language (OGNL) input (CWE-917): an attacker with network access to the application can submit a crafted request that is evaluated as an expression and executed by the server. Successful exploitation lets a remote, unauthenticated attacker run arbitrary code with the privileges of the Confluence process, without any credentials. All organizations running self-managed Confluence Server or Data Center are affected, particularly instances exposed to the internet; Confluence Cloud is not listed among the affected products. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2022-06-02 with ransomware use marked as known, and EPSS assigns a 100% probability of exploitation within 30 days (100th percentile). CVSS has not yet been scored in this data, but the KEV listing and known ransomware use make unpatched, internet-facing instances a top-priority patching target.

Command Injection RCE in Alcatel OmniPCX Enterprise masterCGI
CVE-2007-3010 is a command execution flaw in masterCGI, a component of the Unified Maintenance Tool in the Alcatel OmniPCX Enterprise Communication Server. Because the CGI fails to properly validate user-supplied input (CWE-20), a remote attacker can send crafted requests to the web-based maintenance interface and inject arbitrary operating system commands, which are executed on the PBX server. Successful exploitation yields remote code execution on the communication server, giving attackers a foothold on a Linux-based edge device that could be used for further compromise, lateral movement into the voice network, or, per recent botnet trends, conscription into proxy botnets. Any organization running an Alcatel OmniPCX Enterprise communication server with the Unified Maintenance Tool reachable is affected. The flaw is listed in CISA's Known Exploited Vulnerabilities catalog (added 2022-04-15) with a very high 97.4% EPSS score, indicating active in-the-wild exploitation, though no public proof-of-concept code is known.

OS Command Injection in D-Link DNS-320/320LW/325/340L NAS Firmware
CVE-2024-10914 is a critical OS command injection flaw (CWE-74/CWE-78/CWE-707) in the cgi_user_add function of the file /cgi-bin/account_mgr.cgi?cmd=cgi_user_add on D-Link DNS-320, DNS-320LW, DNS-325, and DNS-340L network-attached storage devices. A remote, unauthenticated attacker can trigger it by manipulating the 'name' argument sent to that CGI endpoint, injecting operating system commands that the device executes. Successful exploitation yields arbitrary command execution on the NAS, giving the attacker control of the device — a profile attractive for follow-on actions such as botnet recruitment, consistent with recent IoT botnet activity. Affected devices are the DNS-320, DNS-320LW, DNS-325, and DNS-340L, which news reports describe as end-of-life D-Link NAS models, with all firmware up to 20241028 listed as vulnerable. A public proof-of-concept is available, the EPSS score is 96.2% (top percentile, indicating very high likelihood of exploitation within 30 days), and news headlines indicate hackers are actively targeting the flaw, though it is not yet in CISA KEV.
