CVE-2010-0014
CVSS v2.0
3.7
Low
| Vector | AV:L/AC:H/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
SSSD versions prior to 1.0.1
Description
The issue allows physically proximate attackers to authenticate to the screen-locking program on a workstation using an arbitrary password when the Kerberos authentication provider is configured but the Key Distribution Center (KDC) is unreachable. This occurs if any user has a valid Kerberos ticket-granting ticket (TGT). Additionally, it might enable remote attackers to bypass intended access restrictions by using an arbitrary password in conjunction with a valid TGT.
Recommendations
For versions prior to 1.0.1, update to version 1.0.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the screen-locking program or ensuring the KDC is always reachable when the krb5 auth provider is configured.
Fix
Improper Authentication
