TYPO3 8.3 < 8.7.27 / 9.x < 9.5.8 XSS (TYPO3-CORE-SA-2019-015)

medium Nessus Plugin ID 138796

Language:

Synopsis

The remote web server contains a PHP script that is affected by a cross-site scripting vulnerability.

Description

The version of TYPO3 installed on the remote host is 8.3 prior to 8.7.27 or 9.x prior to 9.5.8. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in its t3 URL handling component due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version

Solution

Upgrade to TYPO3 8.7.27, 9.5.8 or later.
