Vulnerability Overview

The WP Super Cache WordPress plugin before 1.7.2 was affected by an authenticated (admin+) RCE in the settings page due to input validation failure and weak $cache_path check in the WP Super Cache Settings -> Cache Location option. Direct access to the wp-cache-config.php file is not prohibited, so this vulnerability can be exploited for a web shell injection.

Technical Analysis

REMEDIATION: Update to version 1.7.2, or a newer patched version --- IDENTIFIER: CWE-20 (Improper Input Validation) The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
