CVE-2016-7030

HIGH
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

FreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts, which allows remote attackers to cause a denial of service by locking out the account in which system services run on.
