CVE-2023-5455: Ipa: invalid csrf protection

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.

Security readout for executives and security teams

Plain-English summary

CVE-2023-5455 is a CSRF weakness in Red Hat IPA/FreeIPA login handling. An attacker could trick a user into making a request that acts with that user's authority, mainly risking unauthorized integrity impact. The source says existing logged-in cookies cannot be reflected, so the attacker needs a new authentication attempt.

Executive priority

Treat this as a moderate identity-platform issue. It is not cited as actively exploited, but IPA/FreeIPA often protects central authentication, so affected servers should be updated during the next security maintenance window, faster if externally reachable.

Technical view

The flaw is CWE-352 in ipa/session/login_password and certain FreeIPA HTTP endpoints that did not consistently enforce CSRF protection. CVSS is 6.5, network-reachable, low complexity, no privileges required, and user interaction required, with high integrity impact and no rated availability impact.

Likely exposure

Exposure is most likely in Red Hat Enterprise Linux systems running affected ipa or idm:DL1 packages for RHEL 7, 8 streams, and RHEL 9 variants listed in the source bundle. RHEL 8 idm:client/ipa and krb5 are listed unaffected; RHEL 6 status is unknown.

Exploitation context

No active exploitation is established by the provided sources, and KEV is false. Exploitation requires social engineering or user interaction that causes a new authentication attempt. The source specifically limits the cookie-reflection scenario for an already logged-in user.

Researcher notes

Key constraints matter: user interaction is required, and the source says the flaw cannot reflect an existing logged-in cookie. Validation should focus on package and stream exposure, not generic CSRF assumptions. Evidence for fixed builds is advisory-based in the provided bundle, without full package changelog details.

Mitigation direction

  • Apply the relevant Red Hat RHSA security update for the affected RHEL stream.
  • Review FreeIPA release notes referenced for supported upgrade paths.
  • Prioritize internet-exposed or broadly reachable IPA web interfaces.
  • Do not assume RHEL 6 status; check Red Hat guidance directly.
  • Confirm RHEL 8 client-only idm and krb5 packages are not in scope.

Validation and detection

  • Inventory hosts running ipa or idm:DL1 packages.
  • Map each host to the affected RHEL version or stream listed in the bundle.
  • Check installed package versions against Red Hat advisory guidance.
  • Verify IPA web endpoints are not unnecessarily exposed to untrusted networks.
  • Document whether RHEL 6 instances exist and require vendor clarification.
