Exploit-DB
Moodle 2.0.1 - 'PHPCOVERAGE_HOME' Cross-Site Scripting
source: https://www.securityfocus.com/bid/46085/info
Moodle is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.
Exploiting this vulnerability may allow an attacker to perform cross-site scripting attacks on unsuspecting users in the context of the affected website. As a result, the attacker may be able to steal cookie-based authentication credentials and to launch other attacks.
Versions prior to Moodle 2.0.1 are vulnerable.
