Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Client_connector | Zscaler | * | 3.7 (excluding) |
Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
