Summary

RT is a ticket tracking system where versions up to 5.0.9 and 6.0.0-6.0.2 contain an authentication bypass vulnerability in LDAP/AD setups. An attacker can authenticate as any LDAP-backed user without valid credentials.

Risk Assessment

An attacker can gain full access to the ticket system, including sensitive tickets and user data, without needing any credentials.

Recommendation

Upgrade RT to version 5.0.10 or 6.0.3 immediately. If upgrade is not possible, temporarily review your LDAP server's authentication policy to reject unauthenticated bind attempts.

Original NVD description (English source)

RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.9 and prior in addition to 6.0.0 through 6.0.2 contain an authentication bypass vulnerability in RT installations that use LDAP/AD for user authentication. Under certain LDAP server configurations, an attacker may be able to authenticate as any LDAP-backed RT user without supplying valid credentials. This issue has been fixed in versions 5.0.10 and 6.0.3. If developers are unable to upgrade immediately, they can temporarily work around this issue by reviewing their LDAP server's authentication policy to ensure it rejects unauthenticated bind attempts. Upgrading RT remains the recommended fix.
