Detailsinfo

A vulnerability has been found in Mellium SASL up to 0.3.0 and classified as problematic. This vulnerability affects an unknown function of the component SCRAM-based SASL Authentication. The manipulation with an unknown input leads to a random values vulnerability. The CWE definition for the vulnerability is CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The weakness was shared 12/31/2022. The advisory is shared for download at mellium.im. This vulnerability was named CVE-2022-48195 since 12/30/2022. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.001.

Upgrading to version 0.3.1 eliminates this vulnerability.
