- 漏洞讨论

GDM is susceptible to an authentication-bypass vulnerability when users try to access the 'Configure Login Manager' option.

This issue allows local attackers to execute the 'Configure Login Manager' option with superuser privileges without entering valid superuser credentials. This allows them to make unauthorized configuration changes, which in turn grants them administrative access to affected computers, facilitating their complete compromise.

- 漏洞利用

Attackers use the application itself to exploit this issue.

- 解决方案

This issue has been addressed in the latest CVS repository.

Please see the referenced vendor advisories for more information.
