From 1.11.34 until 3.13.0, the botan ocsp_check command requested an OCSP response from a certificate's Authority Information Access URL without verifying the response signature or authorizing the signer. A malicious responder or on-path attacker could return a matching and timely GOOD response with an empty, invalid, or unauthorized signature, causing a revoked certificate to produce exit status 0 and OCSP check OK output. Only the command-line interface is affected. This issue is fixed in version 3.13.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-347"],"vendors":[],"products":[],"references":[{"url":"https://github.com/randombit/botan/commit/46b2a9ca59b0797184fbf7537495bda6e61a1983","tags":[]},{"url":"https://github.com/randombit/botan/pull/5825","tags":[]},{"url":"https://github.com/randombit/botan/security/advisories/GHSA-mpr7-9494-4qcw","tags":[]}],"exploitRefs":[{"url":"https://github.com/randombit/botan/commit/46b2a9ca59b0797184fbf7537495bda6e61a1983","tags":[]},{"url":"https://github.com/randombit/botan/pull/5825","tags":[]},{"url":"https://github.com/randombit/botan/security/advisories/GHSA-mpr7-9494-4qcw","tags":[]}],"hasPoc":true,"ai":null}
