CVE-2011-4106 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 23.16% chance of exploitation in the next 30 days.
