Description

The Premmerce Dev Tools plugin for WordPress is vulnerable to Remote Code Execution via missing authorization in versions up to and including 2.0. This is due to the 'generatePluginHandler' function lacking any authorization check before processing user-supplied POST data, combined with the 'createFromStub' function performing unsanitized string substitution of the 'premmerce_plugin_namespace' parameter directly into PHP stub files written to the wp-content/plugins/ directory. An attacker can inject a semicolon followed by arbitrary PHP code into the namespace parameter, causing the generated plugin file to contain and execute that code when accessed via HTTP. This makes it possible for authenticated attackers with Subscriber-level access and above to create arbitrary PHP files on the server and achieve remote code execution.
