Vulnerabilities mentionedAll →
| CVE | Vulnerability | CVSS | EPSS | Flags | Affected | Exposure | Published |
|---|---|---|---|---|---|---|---|
| CVE-2023-22518 | Improper Authorization in Atlassian Confluence Data Center and Server Atlassian Confluence Data Center and Server contain an improper authorization flaw (CWE-863) that can be triggered by an unauthenticated attacker sending crafted requests to a vulnerable instance. Successful exploitation gives the attacker control over the instance and can cause significant data loss, such as wiping or resetting the Confluence site, but there is no confidentiality impact because no data can be exfiltrated. Any organization running a self-managed Confluence Data Center or Server deployment is in scope. Exploitation is active: the flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2023-11-07 with ransomware use noted, and EPSS assigns it a 100% probability of exploitation within 30 days. No public proof-of-concept is known, but ransomware operators are already using the flaw in the wild. Do: Upgrade every Confluence Data Center and Server instance to the patched release for your branch listed in Atlassian's advisory, per the CISA KEV required action (apply vendor mitigations or discontinue use). In the interim, restrict internet access to Confluence and check for signs of compromise such as unexpected instance resets, missing data, or ransom notes; restore from backups if data loss is detected. | 9.8 | 100% | KEV ransomware PoC |
| large≈70,000+ internet-exposed Confluence instances per public scans, likely 100k+ total self-managed installations | |
| CVE-2023-47246 | Unauthenticated Path Traversal RCE in SysAid On-Premise Server CVE-2023-47246 is a critical (CVSS 9.8) path traversal flaw (CWE-22) in SysAid On-Premise before version 23.3.36 that allows an unauthenticated, network-located attacker to write attacker-controlled files into the Tomcat webroot of the SysAid server. Once a file is written into that webroot, it is executed by the Tomcat application server, resulting in remote code execution on the ITSM server. Because the flaw requires no authentication or user interaction, any internet-exposed SysAid On-Premise server is directly reachable, and compromise can lead to data theft and ransomware deployment; the Lace Tempest group behind the MOVEit attacks has exploited it, and ransomware use is known. Only SysAid On-Premise deployments are affected, and the vendor fixed the issue in version 23.3.36. The vulnerability is confirmed exploited in the wild, was added to CISA's Known Exploited Vulnerabilities catalog on 2023-11-13, and carries a 98.9% EPSS probability of exploitation within 30 days. Do: Upgrade SysAid On-Premise to version 23.3.36 or later immediately, per the vendor's security notification. Because this is KEV-listed with known ransomware use by Lace Tempest, also inspect the Tomcat webroot and deployed webapps for unauthorized files (e.g., WAR files), review for unauthorized accounts and unusual processes, and check for signs of lateral movement on compromised hosts. Organizations unable to patch should apply mitigations per the vendor's instructions or discontinue use of the product, per the CISA required action. | 9.8 | 99% | KEV ransomware PoC |

| CVE-2023-4911 | Buffer Overflow in GNU C Library ld.so Grants Root via SUID Binaries CVE-2023-4911 ('Looney Tunables') is a buffer overflow in the GNU C Library's dynamic loader (ld.so) that occurs while processing the GLIBC_TUNABLES environment variable. A local attacker triggers it by launching a set-user-ID (SUID) binary with a maliciously crafted GLIBC_TUNABLES value, corrupting memory in the privileged process. This allows the attacker to execute code with elevated (root) privileges on the host. Any system running an affected glibc is potentially exposed, including major Linux distributions (Fedora, Red Hat, Canonical, Debian), Red Hat CodeReady Linux Builder channels, NetApp products, and Siemens SIMATIC S7-1500 firmware, although exploitation requires local execution capability or a foothold on the machine. Exploitation is confirmed in the wild: Qualys published a working proof-of-concept, the flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2023-11-21, and Kinsing threat actors have used it for cryptojacking and to breach cloud environments. Do: Install patched glibc updates from your distribution vendor (Fedora, Red Hat, Canonical/Ubuntu, Debian) and apply Siemens firmware updates for affected SIMATIC S7-1500 MFP devices; NetApp customers should follow NetApp's remediation guidance. Until patched, audit SUID/SGID binaries (which the attacker needs as the escalation trigger) and limit untrusted local access and shell access on multi-user or cloud-hosted Linux systems. Per the CISA KEV required action, apply vendor mitigations or discontinue use, prioritizing internet-facing hosts given active Kinsing cryptojacking and cloud-breach activity. | 7.8 | 81% | KEV PoC ×6 |
