## Technical details

Multiple remote code execution vulnerabilities in Zscaler Client Connector allow unauthenticated, unprivileged users to execute arbitrary code in the ZCC context. The vulnerabilities are network-reachable and require no user interaction or prior authentication. Successful exploitation grants an attacker code execution in the security context of the Client Connector application, which runs with elevated system privileges on the endpoint. Zscaler has published patched versions addressing these flaws; affected users should upgrade immediately.
