Security Discussion

TYPO3 is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.

This issue affects the following versions:

TYPO3 4.4.0 through 4.4.14
TYPO3 4.5.0 through 4.5.14
TYPO3 4.6.0 through 4.6.7
TYPO3 4.7 branch releases

Proof of Concept and Security Exploits

Attackers can exploit this issue by enticing an unsuspecting victim into following a malicious URI.
