CVE-2024-6312: funnelforms free vulnerability

What is known

The Funnelforms Free plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 3.7.3.2 via the 'af2DeleteFontFile' function. This is due to the plugin not properly validating a file or its path prior to deleting it. This makes it possible for authenticated attackers, with administrator-level access and above, to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible.

Business impact

Successful exploitation of CVE-2024-6312, a medium vulnerability (CVSS 6.5) affecting funnelforms free, 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 funnelforms free is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
