Summary
A vulnerability categorized as CVE-2024-23463 (CVSSv3: 8.8), is present in the Zscaler Client Connector in versions prior to 4.2.1. It allows the anti-tampering protection of the client to be bypassed when the Repair App functionality is running under certain conditions.
Impact Assessment

The anti-tampering protection is meant to prevent non-admin end users from stopping, modifying, and deleting Zscaler products and services off of their machines. This can potentially undermine the use of Zscaler within an organization, removing the protections it is intended to provide.
Remediation
Patching to version 4.2.1 or later will remediate this vulnerability. However, known issues with the anti-tampering service on some versions released in 2023 should be accommodated. See the app release summary for 2023 and 2024 for guidance on the appropriate upgrade version. Currently the most up-to-date version 4.4.0.285 has no known issues and should remediate the vulnerability.
See best practices for updating the Zscaler Client Connector.
