CVE-2017-12173

Name of the Vulnerable Software and Affected Versions sssd versions prior to 1.16.0

Description The issue is related to insufficient input validation in the sysdb search user by upn res() function of the sssd service, which manages access to remote directories and authentication mechanisms. This flaw can be exploited by a remote attacker to gain unauthorized access to protected information. In a centralized login environment, if a password hash is locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.

Recommendations For versions prior to 1.16.0, update to version 1.16.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the local cache to minimize the risk of exploitation.
