1) Improper Authentication (CVE-ID: CVE-2023-38201)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear


The vulnerability allows a local user to bypass authentication.

The vulnerability exists due to an error in the challenge-response protocol implementation during agent registration. A local user can  impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database.
