Responsive Menu < 4.0.4 - CSRF to Settings Update

In the Reponsive Menu (free and Pro) WordPress plugins before 4.0.4, attackers could craft a request and trick an administrator into importing all new settings. These settings could be modified to include malicious JavaScript, therefore allowing an attacker to inject payloads that could aid in further infection of the site.

Responsive Menu < 4.0.4 - CSRF to Arbitrary File Upload

In the Reponsive Menu (free and Pro) WordPress plugins before 4.0.4, attackers could craft a request and trick an administrator into uploading a zip archive containing malicious PHP files. The attacker could then access those files to achieve remote code execution and further infect the targeted site.

Responsive Menu 4.0.0 - 4.0.3 - Authenticated Arbitrary File Upload

In the Reponsive Menu (free and Pro) WordPress plugins before 4.0.4, subscribers could upload zip archives containing malicious PHP files that would get extracted to the /rmp-menu/ directory. These files could then be accessed via the front end of the site to trigger remote code execution and ultimately allow an attacker to execute commands to further infect a WordPress site.

The responsive-menu plugin before 3.1.4 for WordPress has no CSRF protection mechanism for the admin interface.
