NotrinosERP arbitrary file upload in HRM employee documents

Severity: high · CVSS 8.8 · Published 2026-07-10

NotrinosERP, an enterprise resource planning system, contains a flaw in its human resources module that allows authorized users to upload malicious files. An attacker with basic HR permissions can upload a script that executes on the server, potentially leading to a full system takeover, data theft, or service disruption. This occurs because the system does not properly check the type of files being uploaded in the employee documents section.

Technologies: notrinos/notrinos-erp (Packagist). Vendors: Packagist.

Technical details

An authenticated user with the 'SA_EMPLOYEE' permission can perform an unrestricted file upload in 'hrm/manage/employees.php' via the 'tab_documents()' function. The application fails to validate file extensions, MIME types, or content, and uses the client-provided filename verbatim when storing the file in a web-accessible directory ('company/0/documents/employees/'). By uploading a .php file, an attacker can achieve remote code execution (RCE). Additionally, the lack of filename sanitization may allow for path traversal (CWE-22) and stored cross-site scripting (CWE-79) in the 'View' link generation.
