Summary

The vCenter Server contains multiple heap-overflow vulnerabilities in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger these vulnerabilities by sending a specially crafted network packet potentially leading to remote code execution.

Recommendations

To remediate CVE-2024-37079, and CVE-2024-37080 apply the updates listed in the ‘Fixed Version’ column of the ‘Response Matrix’ below to affected deployments. You can find the ‘Response Matrix’ at the bottom of this post.

What we are doing

DIVD is currently working to identify parties that are running a vulnerable version of vCenter Server and to notify these parties. We do this by looking at the version numbers if possible. Although our fingerprinting cannot confirm if instances are vulnerable to the initial attack vector, we want to issue a warning that a critical infrastructural component is exposed if it falls within the specified vulnerable versions.
