CVE-2023-7045Public exploitNetwork attack vector

Account takeover via blindly relayed KAS redirects

Published May 23, 2024 · Updated Sep 18, 2024

CSRF in affected GitLab CE/EE releases allows remote authenticated users to steal anti-CSRF tokens through Kubernetes Agent Server redirects. The KAS Kubernetes API proxy blindly relays redirects returned by an attacker-controlled cluster, allowing the browser to send its X-CSRF-Token header to an attacker endpoint. Exploitation requires a connected malicious cluster, a signed-in user with project access, and Firefox interaction; the stolen token permits requests as that user, including account changes.
