AI Analysis

Impact

A directory traversal flaw exists in the Syslog server component of VMware vCenter. The vulnerability permits a malicious actor with network access to traverse directories on the host, potentially allowing arbitrary code execution. The weakness aligns with path traversal (CWE-22).

Affected Systems

The flaw impacts VMware Cloud Foundation, VMware Telco Cloud Infrastructure version 3.0, VMware Telco Cloud Platform (all releases), VMware vCenter Server 8.0—including all update streams through update3j—and VMware vSphere Foundation (all releases).

Risk and Exploitability

The CVSS score of 9.8 indicates high severity, and the EPSS score of 46% indicates a high exploitation probability. The vulnerability is listed in the CISA KEV catalog. Exploitation would require an attacker to be reachable over the network to the vCenter Syslog server, after which unvalidated file path processing could lead to code execution.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Restrict network access to the vCenter Syslog server by configuring firewalls or proxies to limit connections to trusted hosts
  • Disable the Syslog server feature or restrict its file path handling to prevent untrusted input
  • Apply the vendor’s official patch or upgrade to a fixed version as soon as it becomes available
