This vulnerability could potentially lead to unauthorized access to sensitive information or data manipulation within the affected Moodle instances.

The vulnerability allows remote attackers to bypass cryptographic protection mechanisms by exploiting a hardcoded password in the rc4encrypt function.

Remediation

To remediate this vulnerability, users of affected Moodle versions should upgrade to version 2.2.1 or later, where the hardcoded password issue has been addressed. It is recommended to update Moodle installations to the latest available version to mitigate the risk of exploitation.
