## Technical details

An improper certificate validation vulnerability (CWE-295) exists in the Ivanti Secure Access Client on Windows. The root cause is a failure to correctly validate the identity of server-side certificates during the connection process. A remote, unauthenticated attacker can exploit this by intercepting or redirecting network traffic to a malicious server. Successful exploitation requires minimal user interaction (UI:R) and can result in remote code execution (RCE) with high impact on confidentiality, integrity, and availability. Ivanti has released version 22.8R6 to address this issue.
