CVE-2010-5099
TYPO3 Path Traversal vulnerability
CVE-2010-5099 is a medium vulnerability (CVSS 6.8) in Typo3, published May 30, 2012. Public exploit code exists. EPSS puts the chance of exploitation in the next 30 days at 3.08%, the 87th percentile. Fixed in typo3/cms 4.2.16.
The fileDenyPattern functionality in the PHP file inclusion protection API in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 does not properly filter file types, which allows remote attackers to bypass intended access restrictions and access arbitrary PHP files, as demonstrated using path traversal sequences with %00 null bytes and CVE-2010-3714 to read the TYPO3 encryption key from localconf.php.
