CRITICAL 9.4

DescriptionCVE.org

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.

AnalysisAI

Remote code execution in OCS Inventory NG's Ocsreports web console (admin_info CSV upload endpoint) allows an authenticated administrator to upload a PHP webshell that, once processed, runs arbitrary code as the web-service account. The upload routine trusts the client-supplied filename and never validates file content or securely restricts extensions (CWE-434), so a benign-looking CSV import becomes a code-execution primitive. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated OCS Inventory NG administrator session (CVSS PR:H) with access to the Ocsreports admin_info CSV upload feature; the attacker must be able to reach the web console over the network (AV:N) but needs no user interaction (UI:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base of 9.4 is driven largely by high vulnerable- AND subsequent-system impact metrics (VC/VI/VA and SC/SI/SA all High); however, the described behavior is single-system RCE with no genuine scope change, so the subsequent-system High ratings appear overstated - an assessed base nearer 8.7 (SC/SI/SA:N) is more defensible. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No exact fixed version is provided in the input, so patch status is: patch guidance available per the INCIBE advisory (https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-ocsreports-ocs-inventory-ng) - upgrade to the vendor-corrected Ocsreports release referenced there and do not invent a version. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, immediately restrict administrative access to the Ocsreports console to a minimal set of trusted users, implement IP whitelisting if possible, and disable the CSV import feature unless it is essential to current operations. …
