CVE-2020-1984: Secdo: Privilege escalation via hardcoded script path
First published: Wed Apr 08 2020(Updated: )
Secdo tries to execute a script at a hardcoded path if present, which allows a local authenticated user with 'create folders or append data' access to the root of the OS disk (C:\) to gain system privileges if the path does not already exist or is writable. This issue affects all versions of Secdo for Windows.
