Detailsinfo

A vulnerability classified as very critical was found in R-SOFT SERWIS DMS up to 3.19-2861. This vulnerability affects the function OCR Function of the component OCR Module. The manipulation of the argument file paths with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at cert.pl. This vulnerability was named CVE-2026-41880 since 04/22/2026. The exploitation appears to be easy. The attack can be initiated remotely.
