Name of the Vulnerable Software and Affected Versions
System Security Services Daemon (SSSD) (affected versions not specified)
Description
A security issue exists in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. By default, SSSD does not enable the Kerberos local authentication plugin (
sssd krb5 localauth plugin). This allows an attacker who can modify specific Active Directory attributes, such as userPrincipalName or samAccountName, to impersonate privileged users. Successful exploitation can lead to unauthorized access or privilege escalation on domain-joined Linux hosts.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
