Remote Code Execution in TimThumb Plugin for WordPress
CVE-2011-4106
Currently unrated
What is CVE-2011-4106?
The TimThumb script (timthumb.php) prior to version 2.0 fails to adequately validate sources against a defined whitelist. This oversight allows attackers to exploit the vulnerability by uploading and executing arbitrary code. This can occur by leveraging a URL that matches the whitelist criteria within the 'src' parameter, followed by a direct file access to the cached version. This security flaw was notably exploited in the wild starting August 2011, making it essential for WordPress users to update their TimThumb installations to mitigate potential risks.
