Prioritize patching. It under exploitation confirmed by CISA and has a public proof of concept.
Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
VMware vCenter's Syslog server contains a flaw that lets attackers access files outside their intended directory through specially crafted requests. An attacker with network access can exploit this to run malicious code on the system.
A directory traversal vulnerability (CWE-22) exists in vCenter's Syslog server component, allowing an unauthenticated or network-adjacent attacker to bypass access controls and read/write arbitrary files on the system. Successful exploitation can lead to remote code execution with vCenter privileges.
