Technical details
This vulnerability is a CWE-427 uncontrolled search path (DLL/binary hijacking) issue. The Mattermost Desktop App versions up to 5.8.0 search for cmd.exe without specifying an absolute path, causing Windows to search in predictable locations including the user's current working directory and Downloads folder. A local attacker with write access to a target user's Downloads folder can place a malicious cmd.exe binary that will be executed with the user's privileges when the application launches. The attack requires local file system access and user interaction (app launch), but no authentication. The vulnerability is fixed in version 5.9.0.
