Risk Analysis

A heap overflow vulnerability exists in VMware vCenter Server due to the use of uninitialized memory in the DCERPC protocol. This allows remote attackers to execute arbitrary code on the host system.

No public exploit is known, and it is not in the KEV catalog. The vulnerability is remotely exploitable with low complexity.

Recommended Action

Update to the latest security patches for VMware vCenter Server 7.0 and 8.0.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-20892 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
