Security readout for executives and security teams
Plain-English summary
An authenticated Ocsreports administrator can upload a PHP file through the admin_info CSV upload function because validation relies on the client-supplied filename. If the web server processes that file, the attacker could take control of the application and potentially affect connected systems or data.
Executive priority
Treat confirmed Ocsreports 2.12.6 deployments as an urgent remediation item, especially when administration is internet-accessible. Prioritize access restriction, compromise review, and vendor-supported remediation. The high impact justifies urgency despite the administrator-level prerequisite and absence of documented active exploitation.
Technical view
CVE-2026-76174 is a CWE-434 unrestricted file upload in OCS Inventory NG Ocsreports 2.12.6. Exploitation requires network access and administrator privileges but no user interaction. A malicious PHP upload to a web-accessible directory may enable arbitrary code execution under the web-service account. The CVSS 4.0 score is 9.4.
Likely exposure
The supplied record identifies Ocsreports 2.12.6 as affected and lists other versions as unaffected by default. Greatest exposure exists where administrators can remotely reach admin_info and the server executes uploaded PHP files. The evidence does not establish whether custom configurations or adjacent versions are affected.
Exploitation context
No active exploitation is established: the CVE is not listed as KEV in the supplied bundle, and no cited source claims attacks in the wild. Administrator privileges materially limit initial access, but successful exploitation could provide server-side code execution with the web-service account's permissions.
Researcher notes
The vulnerability depends on filename-only validation, placement in a web-accessible directory, and subsequent server processing. Researchers should verify these conditions defensively without executing payloads. The supplied evidence names only version 2.12.6 and does not identify a fixed version, patch, public proof of concept, or observed exploitation.
Mitigation direction
- Check OCS Inventory NG and INCIBE guidance for an approved corrected release or vendor mitigation.
- Restrict Ocsreports administrative access to trusted users and networks until remediation is confirmed.
- Review administrator accounts and revoke unnecessary or suspicious privileges.
- Prevent uploaded directories from executing PHP where operationally safe and vendor-supported.
- Back up required data, then test vendor remediation before production deployment.
Validation and detection
- Inventory Ocsreports deployments and confirm whether version 2.12.6 is installed.
- Determine whether the admin_info CSV upload function is reachable by administrator accounts.
- Verify whether the upload destination is web-accessible and configured to execute PHP.
- Review upload directories and access logs for unexpected PHP files or suspicious administrative activity.
- After remediation, confirm the affected workflow rejects unauthorized file types without executing uploaded content.

Unrestricted Upload of File with Dangerous Type
Unrestricted Upload of File with Dangerous Type represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
