Description Vasyl Kaigorodov 2014-11-24 16:09:08 UTC

It was reported [1] that lib/setup.php in Moodle through 2.4.11, 2.5.x before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3 does not provide charset information in HTTP headers, which might allow remote attackers to conduct cross-site scripting (XSS) attacks via UTF-7 characters during interaction with AJAX scripts.
Upstream patch that fixes this is at [2].
More information can be found at [3].
