{"id":"GHSA-9w7j-q3xw-p9vh","summary":"Hyperledger Fabric subject to Denial of Service via non-validated request","details":"A vulnerability exists in Hyperledger Fabric \u003c 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.","aliases":["CVE-2022-35253"],"modified":"2023-11-08T04:09:50.655742Z","published":"2022-09-25T00:00:26Z","database_specific":{"github_reviewed_at":"2022-09-28T14:12:31Z","nvd_published_at":"2022-09-23T14:15:00Z","cwe_ids":["CWE-20","CWE-400"],"severity":"HIGH","github_reviewed":true},"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"}],"affected":[{"package":{"name":"github.com/hyperledger/fabric","ecosystem":"Go","purl":"pkg:golang/github.com/hyperledger/fabric"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.4.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-9w7j-q3xw-p9vh/GHSA-9w7j-q3xw-p9vh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
