WP Super Cache <= 1.7.1 - Authenticated (Admin+) Remote Code Execution

Improper Input Validation

CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

CVE	CVE-2021-24209
CVSS	High (7.2)
Publicly Published	March 16, 2021
Last Updated	January 22, 2024
Researcher	R3N0

Description

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.
