Description

This security bulletin contains information about 1 vulnerability.


1) Authentication Bypass by Alternate Name (CVE-ID: CVE-2025-8415)

CWE-ID: CWE-289 - Authentication Bypass by Alternate Name

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to missing authentication in Cryostat HTTP API bound by default to 0.0.0.0 port 8181/tcp. A remote non-authenticated attacker within the cluster can under certain circumstances determine the internal Pod IP of the Cryostat container and sent HTTP requests directly to its API port, bypassing the openshift-oauth-proxy completely
