CVE-2024-23457

Local anti-tampering bypass with uninstall password enforced

Published May 1, 2024 · Updated Aug 1, 2024

Improper privilege management in Zscaler Client Connector before 4.2.0.209 allows local users to disable anti-tampering on Windows. Zscaler states that the bypass occurs when an uninstall password is enforced but has not published the affected component or the operation that defeats the protection. A low-privileged local session and the password-enforced configuration are required; successful exploitation removes the client's resistance to tampering.
