mellium.im/sasl authentication failure due to insufficient nonce randomness
CVE-2022-48195 · GHSA-gvfj-fxx3-j323
- Affected
- Go mellium.im/sasl < 0.3.1
- Fixed in
- 0.3.1· Vendor fix available
- Issue
- An issue was discovered in Mellium mellium.im/sasl before 0.3.1. When performing SCRAM-based SASL authentication, if the remote end advertises support for channel binding, no random nonce is generated (instead, the nonce is empty). This causes authentication to fail in the best case, but (if paired with a remote end that does not validate the length of the nonce) could lead to insufficient randomness being used during authentication.
Recommended action: Upgrade to 0.3.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
