{"id":"CVE-2022-35253","aliases":[],"url":"https://o3.security/vulnerability/CVE-2022-35253","summary":"Hyperledger Fabric subject to Denial of Service via non-validated request","details":"A vulnerability exists in Hyperledger Fabric < 2.4 could allow an attacker to construct a non-validated request that could cause a denial of service attack.  The peer gateway service tries to extract channel and chaincode information from the signed proposal, but it doesn't check the proposal fields for validity. Therefore a malformed proposal might end up crashing the peer service. This issue has been patched in 2.4.6. There are no known workarounds.","published":"2022-09-25T00:00:26Z","modified":"2023-11-08T04:09:50.655742Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/hyperledger/fabric","fixedVersion":"2.4.6"}],"fix":{"url":"https://github.com/hyperledger/fabric/pull/3572","label":"hyperledger/fabric#3572"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-35253"},{"type":"WEB","url":"https://github.com/hyperledger/fabric/pull/3572"},{"type":"WEB","url":"https://github.com/hyperledger/fabric/pull/3576"},{"type":"WEB","url":"https://github.com/hyperledger/fabric/pull/3577"},{"type":"PACKAGE","url":"https://github.com/hyperledger/fabric"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:09:50.655742Z"}}
