CVE-2024-23462

Client functionality loss via missing installer integrity check

Published May 2, 2024 · Updated Aug 1, 2024

Improper integrity validation in Zscaler Client Connector before 3.4 allows local users to interrupt client functionality on macOS. The macOS validinstaller path omits an integrity check on an installer file, so tampering with that file can stop the Client Connector binary. A low-privileged local account is required, and the reported consequence is loss of client functionality rather than data access or modification.
