Vulnerability from github – Published: 2023-10-05 12:30 – Updated: 2025-05-20 09:30

Details

1E Client installer can perform arbitrary file deletion on protected files.

A non-privileged user could provide a symbolic link or Windows junction to point to a protected directory in the installer that the 1E Client would then clear on service startup. A hotfix is available Q23092 that forces the 1E Client to check for a symbolic link or junction and if it finds one refuses to use that path and instead creates a path involving a random GUID.

Severity ?

7.3 (High)
