GHSA-QQQC-GW7P-PW85

Vulnerability from github – Published: 2026-05-05 12:31 – Updated: 2026-05-05 12:31
VLAI
Details

RouterOS provides various services that rely on correct verification of client and server certificates to secure confidentiality and integrity of communications. This includes OpenVPN, CAPsMAN, Dot1x (802.1X), among others.

The vulnerability lies in shared certificate validation logic which uses the system certificate store that is shared and equally trusted by all system services. This causes confusion of scope, allowing any certificate authority present in the system-wide trust store to be trusted in any context (with some exceptions), allowing partial or full authentication bypass in CAPsMAN, OpenVPN, Dot1X and potentially others.

Severity
6.5 (Medium)

Summary
ex_webrtc client-role handshake is missing DTLS peer fingerprint validation
Details

Summary

Missing DTLS peer certificate fingerprint validation in the DTLS client (active) role removes one side of WebRTC's mutual authentication. The bug is not independently exploitable for media interception in standard deployments, but enables a full man-in-the-middle attack when chained with insecure signalling or a peer with similar validation gaps.

Details

ex_webrtc validates the DTLS peer's certificate fingerprint against the value advertised in the SDP offer/answer when acting as the DTLS server (passive role). When acting as the DTLS client (active role) -- the default when answering a remote offer with a=setup:actpass, which is what browsers always send -- the fingerprint check was skipped on the handshake-completion code path that returns no outgoing packets. This is the most common deployment mode (e.g., an SFU or media server answering a browser's offer).

All released versions prior to 0.15.1 and 0.16.1 are affected. No backports to older lines are planned -- users should upgrade to 0.15.1 or 0.16.1.

Impact

The bug eliminates one half of WebRTC's mutual DTLS authentication. The security of the media and data-channel encryption then rests entirely on the remote peer's fingerprint check.

On its own, the bug does not allow:

  • Passive eavesdropping on SRTP media.
  • A network-positioned attacker to intercept media against a standards-compliant browser peer over a TLS-protected signalling channel -- the browser's fingerprint check prevents the second leg of the MITM from succeeding.

The bug does enable a full MITM on media and data channels when combined with any of:

  • Insecure signalling (HTTP / plain WebSocket) allowing SDP rewrite in transit.
  • A compromised or malicious signalling server.
  • A peer implementation with a similar fingerprint-validation gap.

Both audio/video media (SRTP) and data channels (SCTP-over-DTLS) are affected.

Patches

  • 0.15.1 (for the 0.15.x line)
  • 0.16.1 (for the 0.16.x line)

Workarounds

None. Upgrade is required.

Mitigation
Architecture and Design Implementation

Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.

Mitigation
Implementation

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.
