Security readout for executives and security teams
Plain-English summary
CVE-2020-25688 affects rhacm installations before 2.0.5 and before 2.1.0. Two internal service APIs used the same test certificate across installations. Someone already able to observe internal cluster traffic could decrypt protected API requests and potentially see sensitive information.
Executive priority
Prioritize remediation for clusters running affected rhacm versions where internal network visibility is broadly available. This is a confidentiality issue with constrained attacker position, not a cited active exploitation emergency.
Technical view
The issue is CWE-321: use of a hard-coded cryptographic key. Internal service APIs were provisioned with a test certificate and private key from the source repository, making TLS confidentiality ineffective against a passive internal traffic observer. The source states these certificates were not used for service authentication, so impersonation and active MITM were not enabled.
Likely exposure
Exposure is limited to rhacm deployments older than 2.0.5 or older than 2.1.0, especially clusters where an attacker could observe internal service traffic. Public internet exposure is not indicated by the sources.
Exploitation context
The source bundle does not show CISA KEV listing, active exploitation, public exploit use, or a CVSS score. The described attack requires internal cluster traffic visibility and is passive decryption, not authentication bypass or active interception.
Researcher notes
Evidence is narrow but clear: shared test certificates undermine TLS confidentiality for two internal APIs. No CVSS, exploit status, detailed API names, or vendor remediation procedure beyond affected-version boundaries is provided in the bundle.
Mitigation direction
- Upgrade affected rhacm deployments to 2.0.5, 2.1.0, or a later vendor-supported release.
- Review Red Hat guidance for any certificate rotation or cleanup steps.
- Restrict access paths that allow observation of internal cluster network traffic.
- Treat potentially exposed internal API data as sensitive until assessed.
Validation and detection
- Inventory rhacm versions across all clusters and flag versions before 2.0.5 or before 2.1.0.
- Confirm whether affected internal service APIs still use the repository test certificate.
- Review who can capture or observe internal cluster service traffic.
- Check vendor advisories for any additional validation guidance.

Use of Hard-coded Cryptographic Key
Use of Hard-coded Cryptographic Key represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
