7.8

High

Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Comodo Antivirus versions up to 12.0.0.6810

Description The issue allows a local process to bypass the signature check enforced by CmdAgent via process hollowing, enabling the process to invoke sensitive COM methods in CmdAgent, such as writing to the registry with SYSTEM privileges. This can lead to Local Privilege Escalation.

Recommendations For Comodo Antivirus versions up to 12.0.0.6810, as a temporary workaround, consider restricting access to the CmdAgent's COM methods to minimize the risk of exploitation. However, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
