6.6 · MEDIUMOverview
CVE-2023-6449 is a medium-severity vulnerability affecting rocklobster contact_form_7. It was published on December 1, 2023 and has a CVSS 3.1 base score of 6.6 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.6, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
The Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'validate' function and insufficient blocklisting on the 'wpcf7_antiscript_file_name' function in versions up to, and including, 5.8.3. This makes it possible for authenticated attackers with editor-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed in most cases. By default, the file will be deleted from the server immediately. However, in some cases, other plugins may make it possible for the file to live on the server longer. This can make remote code execution possible when combined with another vulnerability, such as local file inclusion.
Remediation
Check the references section for vendor advisories and patches from rocklobster. Update contact_form_7 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
