Detailsinfo

A vulnerability was found in IO FinNet tss-lib up to 1.x. It has been rated as problematic. This issue affects some unknown functionality of the component MPC Handler. The manipulation of the argument ssid with an unknown input leads to a random values vulnerability. Using CWE to declare the problem leads to CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. Impacted is confidentiality. The summary by CVE is:

An issue was discovered in IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session id, context, or random nonce in the generation of the challenge. This could allow a malicious user or an eavesdropper to replay a valid proof sent in the past.

The weakness was presented 04/21/2023. The advisory is shared at github.com. The identification of this vulnerability is CVE-2022-47930 since 12/22/2022. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 216199 (SUSE SLES15 / openSUSE 15 Security Update : govulncheck-vulndb (SUSE-SU-2025:0429-1)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 2.0.0 eliminates this vulnerability. The upgrade is hosted for download at github.com.
