CVE-2014-7828
Description
From CVE.org
FreeIPA 4.0.x before 4.0.5 and 4.1.x before 4.1.1, when 2FA is enabled, allows remote attackers to bypass the password requirement of the two-factor authentication leveraging an enabled OTP token, which triggers an anonymous bind.
Statement
This issue did not affect the versions of IPA as shipped with Red Hat Enterprise Linux 5, 6, or 7 as they did not include support for OTP.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
