WordPress 5.8.x < 5.8.17 Path Traversal

high Web App Scanning Plugin ID 115534

Synopsis

WordPress 5.8.x < 5.8.17 Path Traversal

Description

According to its self-reported version number, the version of WordPress installed on the remote host is missing a security update. It is, therefore, affected by a path traversal vulnerability.

An unauthenticated remote attacker can supply a double-encoded traversal sequence in the pagename query parameter, which get_page_template() interpolates into a page-{pagename}.php candidate without passing it through validate_file(). This allows a readable local .php file located outside the active theme directories to be included, and under specific theme and server conditions (an active theme with a top-level directory whose name starts with page-, and a reachable .php file such as pearcmd.php when register_argc_argv is enabled) it can be escalated to remote code execution.

Note that the scanner has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to WordPress version 5.8.17 or later.
