CVE-2026-76174 — Multiple vulnerabilities in Ocsreports for OCS Inventory NG

Unrestricted file upload vulnerability in the CSV file upload functionality of the Ocsreports admin_info endpoint. The application validates files solely based on the name provided by the client, without properly checking their content or securely restricting the permitted file types. This allows a user with administrator privileges to upload PHP files to a directory accessible via the web interface. If the file is subsequently processed by the server, an attacker could execute arbitrary code with the privileges of the account used by the web service.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

EPSS FIRST

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Ocsinventory-ng Ocsreports).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.
