Summary

CVE-2024-8883 is a medium-severity Open Redirect (CWE-601) vulnerability in Redhat Openshift Container Platform. Its CVSS base score is 6.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Phishing (T1566); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A misconfiguration vulnerability in Keycloak allows an attacker to redirect users to an arbitrary URL when a Valid Redirect URI is configured as http://localhost or http://127.0.0.1. The flaw, tracked as CVE-2024-8883 and assigned CWE-601, carries a CVSS 3.1 score of 6.1 and can expose sensitive values such as authorization codes.

An unauthenticated remote attacker can trigger the open redirect during an OAuth or OIDC flow that involves user interaction, enabling capture of authorization codes and subsequent session hijacking. Exploitation requires the target realm to have the permissive localhost redirect URI setting and does not need authentication or special privileges.

Red Hat has published multiple errata (RHSA-2024:10385, RHSA-2024:10386, RHSA-2024:6878, RHSA-2024:6879, RHSA-2024:6880) that address the issue in affected Keycloak packages; administrators should apply the relevant updates and review redirect URI configurations to restrict them to trusted domains. The associated EPSS score has remained flat at 0.0659 with no material increase since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly checks and rejects untrusted redirect targets before they are used in a response.

Information flow enforcement can restrict redirects to only approved/trusted destinations, stopping untrusted user-supplied URLs from being followed.
