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."}], "lastModified": "2023-11-07T03:56:26.160", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:iofinnet:tss-lib:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5A407DB0-D561-404E-941A-EF988ABB8BDB", "versionEndExcluding": "2.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
