TimThumb <= 1.33 - Remote File Download

Improper Control of Generation of Code ('Code Injection')
CVE CVE-2011-4106
CVSS Critical (9.8)
Publicly Published August 1, 2011
Last Updated January 22, 2024
Researcher Mark Maunder
Description

TimThumb (timthumb.php) before 2.0 does not validate the entire source with the domain white list, which allows remote attackers to upload and execute arbitrary code via a URL containing a white-listed domain in the src parameter, then accessing it via a direct request to the file in the cache directory, as exploited in the wild in August 2011. Note: this is not a WordPress plugin or theme, but may be used by WordPress plugins and themes. Make sure to check for the presence of the timthumb.php file when determining if your installation is vulnerable.
