Description

R-SOFT DMS is vulnerable to OS Command Injection in the Optical Character Recognition (OCR) module. Multiple command execution functions accept user-controllable file paths without proper sanitization before passing them to the system shell via SSH. In current infrastructure the URL encoding neutralizes the injection during the standard web upload flow. An authenticated attacker who is able to trigger the OCR functionality for the uploaded file can execute OS commands within the context of a root user. This issue was fixed in version v3.19-2862 and v3.17-2580.
