In rare deployment cases (error thrown by the Read() function), this could lead to a predictable shared secret.\n\nThe tkn20 and blindrsa components did not check whether enough randomness was returned from the user provided randomness source. Typically the user provides crypto/rand.Reader, which in the vast majority of cases will always return the right number random bytes. In the cases where it does not, or the user provides a source that does not, the blinding for blindrsa is weak and integrity of the plaintext is not ensured in tkn20.\n\n"}],"affected":[{"source":"cna@cloudflare.com","affectedData":[{"vendor":"Cloudflare","product":"CIRCL","defaultStatus":"unaffected","collectionURL":"https://github.com/cloudflare/circl","platforms":["Go"],"versions":[{"version":"0","lessThan":"<1.3.3","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"cna@cloudflare.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.0,"impactScore":4.2},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","baseScore":8.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":4.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-01-27T18:32:18.233703Z","id":"CVE-2023-1732","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"cna@cloudflare.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"},{"lang":"en","value":"CWE-755"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-755"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cloudflare:circl:*:*:*:*:*:go:*:*","versionEndExcluding":"1.3.3","matchCriteriaId":"39A6B412-BB17-403E-B83A-FCFAD155C1B9"}]}]}],"references":[{"url":"https://github.com/cloudflare/circl/security/advisories/GHSA-2q89-485c-9j2x","source":"cna@cloudflare.com","tags":["Vendor Advisory"]},{"url":"https://github.com/cloudflare/circl/security/advisories/GHSA-2q89-485c-9j2x","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
