high Nessus Plugin ID 117582

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the sssd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - It was found that sssd's sysdb_search_user_by_upn_res() function did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.(CVE-2017-12173)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected sssd package.
