| パッケージ | 影響を受けるバージョン | 修正済みバージョン |
|---|---|---|
| drupal/cas_server | ≥ 2.1.0, < 2.1.2< 2.0.3 | 2.1.22.0.3 |
| central authentication system server | ≥ 2.1.0, < 2.1.2< 2.0.3 | 2.1.22.0.3 |
This module enables you to turn a Drupal install into the Central Authentication System (CAS). It makes your database the primary location for other systems to use for authentication in a SSO environment.
The module doesn't sufficiently sanitize user-supplied field values configured to be included as attributes in a CAS server response.
This vulnerability is mitigated by the fact that an attacker must be authenticated, have the ability to enter XML into a user entity field, and that field be configured as a CAS Attribute source leading to an XML Element Injection vulnerability.
