Description

A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.

Statement

The CSRF vulnerability in ipa/session/login_password is considered a moderate issue due to the need for the attacker to trick users into submitting a request. This implies that exploitation requires user interaction for a new authentication attempt, rather than reflecting a cookie for an already logged-in user. While the vulnerability could result in a loss of confidentiality and system integrity, the specific actions and their severity are not explicitly detailed. The moderate classification suggests that, while serious, the limitations on exploitation conditions and potential impact contribute to a moderate overall severity.

Common Vulnerability Scoring System (CVSS) Score Details

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).

Red Hat CVSS v3 Score Explanation

Confidentiality is rated as "none" below vulnerability because the CSRF vulnerability in ipa/session/login_password, though moderate, requires user interaction for exploitation, limiting the ease of attack and potential impact on confidentiality and system integrity. The moderate classification reflects the balance between severity and constrained exploitation conditions.
