CVE-2016-15042

CWE-434Published: October 16, 2024· Updated: Jun 17, 2026

9.8
CVSS v3.1

Official Description

The Frontend File Manager (versions < 4.0), N-Media Post Front-end Form (versions < 1.1) plugins for WordPress are vulnerable to arbitrary file uploads due to missing file type validation via the `nm_filemanager_upload_file` and `nm_postfront_upload_file` AJAX actions. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

Risk Analysis

The Frontend File Manager and N-Media Post Front-end Form plugins for WordPress lack file type validation, allowing unauthenticated attackers to upload arbitrary files. This can lead to remote code execution on the server.

No public exploit is known, and it is not in KEV. The vulnerability is remotely exploitable.

Recommended Action

Update the affected plugins to version 4.0 or 1.1 respectively, or implement strict file type filtering on the server.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2016-15042 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
