R-SOFT DMS vulnerabilities

R-SOFT DMS is vulnerable to OS Command Injection in the OCR module. Command execution functions accept user-controllable file paths without proper sanitization before passing them to the system shell via SSH. In standard web upload flow URL encoding neutralizes the injection, but an authenticated attacker who can trigger OCR for the uploaded file can execute commands as root.

The vulnerability in R-SOFT DMS stores superadmin credentials using a non-salted nested MD5 hash. This allows an attacker who obtains the password hash to decode superadmin credentials. Critically, this password cannot be changed except by modifying the configuration file.

An IDOR vulnerability in R-SOFT DMS allows unauthorized file access by manipulating IDs in download requests. The system does not verify user permissions for specific files, relying solely on session authentication.

Stored XSS vulnerability in the file upload functionality of R-SOFT DMS. An authenticated attacker can inject arbitrary HTML and JavaScript into the uploaded file name, which executes when other users view the file list or upload status.

OS Command Injection vulnerability in the konwertujAction() function of R-SOFT DMS allows an authenticated attacker to execute arbitrary system commands with the privileges of the web server user. The issue is fixed in versions v3.19-2752 and v3.17-2580.
