CVE-2021-4449: zoomsounds vulnerability

What is known

The ZoomSounds plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'savepng.php' file in versions up to, and including, 5.96. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE-2021-4457 is a duplicate of this.

Business impact

Successful exploitation of CVE-2021-4449, a critical vulnerability (CVSS 9.8) affecting zoomsounds, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether zoomsounds is present and compare installed versions with the vendor advisory and NVD record.
