⚠️ Risk & Real-World Impact
Worst Case
An attacker could delete critical system files, modify configuration to disable security controls, or plant malicious executables that execute with client privileges, potentially leading to system compromise or data loss.
Likely Case
Local users could tamper with client configuration files, certificate stores, or log files to disrupt SASE functionality, bypass security policies, or maintain persistence on the system.
If Mitigated
With proper access controls and monitoring, impact is limited to disruption of the SASE client functionality without broader system compromise.
🎯 Exploit Status
Exploitation requires local access to the Windows system. The vulnerability is a path traversal issue (CWE-22) that can be triggered by a local user.
