WordPress Plugin Peugeot Music 1.0 Critical Arbitrary File Upload
The National Vulnerability Database has disclosed a critical arbitrary file upload vulnerability, CVE-2018-25335, in the WordPress Plugin Peugeot Music version 1.0. This flaw allows unauthenticated attackers to upload malicious files directly to affected sites. The vulnerability stems from insufficient validation, enabling attackers to send POST requests to the upload.php endpoint and bypass file extension checks by manipulating the ‘name’ parameter.
With a CVSS score of 9.8 (CRITICAL), this vulnerability poses an extreme risk. Attackers can execute arbitrary code on the server by uploading web shells or other malicious scripts to the uploads directory. This provides a direct path to full system compromise, data exfiltration, and website defacement, all without requiring any authentication.
Defenders must recognize the immediate danger here. If this plugin is active, it’s an open door. The ease of exploitation — unauthenticated POST requests — means automated attacks are highly probable. It’s a prime target for initial access brokers and opportunistic attackers looking to establish a foothold.
What This Means For You
- If your organization uses WordPress and has the Peugeot Music plugin 1.0 installed, you are critically exposed. Immediately disable or remove this plugin. There is no patch for this specific vulnerability in the plugin. Audit your web server logs for any suspicious POST requests to `upload.php` and scan your uploads directory for unknown or recently modified files.
