Moodle Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Vulnerability (CVE-2010-2230)
Description
The KSES text cleaning filter in lib/weblib.php in Moodle before 1.8.13 and 1.9.x before 1.9.9 does not properly handle vbscript URIs, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via HTML input.
