Amazon Linux 1 Security Advisory: ALAS-2017-935
Advisory Release Date: 2017-12-20 18:56 Pacific
Advisory Updated Date: 2017-12-21 22:59 Pacific
Severity:
Medium
Issue Overview:
Unsanitized input when searching in local cache database
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)
