GHSA-GH47-WQWG-V2CM
Vulnerability from github – Published: 2025-09-16 15:32 – Updated: 2025-09-16 15:32An authentication bypass vulnerability exists in the out-of-support Control-M/Agent versions 9.0.18 to 9.0.20 and potentially earlier unsupported versions when using an empty or default kdb keystore or a default PKCS#12 keystore. A remote attacker with access to a signed third-party or demo certificate for client authentication can bypass the need for a certificate signed by the certificate authority of the organization during authentication on the Control-M/Agent.
The Control-M/Agent contains hardcoded certificates which are only trusted as fallback if an empty kdb keystore is used; they are never trusted if a PKCS#12 keystore is used. All of these certificates are now expired.
In addition, the Control-M/Agent default kdb and PKCS#12 keystores contain trusted third-party certificates (external recognized CAs and default self-signed demo certificates) which are trusted for client authentication.

Mitigation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
