Moodle Multiple Input Validation Vulnerabilities

Two input validation vulnerabilities reportedly affect Moodle. These issues are due to a failure of the application to properly sanitize user-supplied input prior to using it in application-critical actions such as generating web content or loading scripts.

The first issue is a cross-site scripting vulnerability. The second issue is a directory traversal issue that may allow attackers to gain access to session data.

An attacker may leverage these issues to execute arbitrary client-side script code in the browsers of unsuspecting users through cross-site scripting attacks and gain access to sensitive session credentials through directory traversal attacks. Other attacks are also possible.
