Technical details

The vulnerability exists in the 'generatePluginHandler' function of the Premmerce Dev Tools plugin due to a lack of authorization checks on POST data. This is compounded by the 'createFromStub' function, which performs unsanitized string substitution of the 'premmerce_plugin_namespace' parameter into PHP stub files. An attacker with Subscriber-level permissions or higher can inject a semicolon and arbitrary PHP code into this parameter. The plugin then writes this malicious code into a new PHP file within the wp-content/plugins/ directory, which can be executed by accessing the file via HTTP. This results in full remote code execution (RCE).
