Support Board WordPress Plugin Arbitrary File Deletion Vulnerability

A vulnerability allowing arbitrary file deletion has been identified in the Support Board plugin for WordPress, affecting all versions through 3.8.0. The issue arises from inadequate file path validation in the 'sb_file_delete' function. This vulnerability enables attackers to delete arbitrary files on the server, potentially leading to remote code execution if critical files, such as 'wp-config.php', are removed. Additionally, this vulnerability can be exploited without authentication, especially when combined with another identified vulnerability in the same plugin.

Impact

Exploitation of this vulnerability allows for unauthenticated arbitrary file deletion, which can lead to remote code execution if a sensitive file is deleted.

Remediation

Users are advised to update the Support Board plugin to version 3.8.1 or a later patched version.
