The revocation scheme that is part of the Ursa CL-Signatures implementations has a flaw that could impact the privacy guarantees defined by the AnonCreds verifiable credential model. Notably, a malicious verifier may be able to generate a unique identifier for a holder providing a verifiable presentation that includes a Non-Revocation proof. The impact of the flaw is that a malicious verifier may be able to determine a unique identifier for a holder presenting a Non-Revocation proof. Ursa has moved to end-of-life status and no fix is expected." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-327: Use of a Broken or Risky Cryptographic Algorithm", "cweId": "CWE-327" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "hyperledger-archives", "product": { "product_data": [ { "product_name": "ursa", "version": { "version_data": [ { "version_affected": "=", "version_value": "<= 0.3.7" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://github.com/hyperledger-archives/ursa/security/advisories/GHSA-6698-mhxx-r84g", "refsource": "MISC", "name": "https://github.com/hyperledger-archives/ursa/security/advisories/GHSA-6698-mhxx-r84g" } ] }, "source": { "advisory": "GHSA-6698-mhxx-r84g", "discovery": "UNKNOWN" }, "impact": { "cvss": [ { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N", "version": "3.1" } ] } }
