The receiver is supposed to respond to each PATH_CHALLENGE frame with a PATH_RESPONSE frame. The attacker can prevent the receiver from sending out (the vast majority of) these PATH_RESPONSE frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate.\n\nI published a more detailed description of the attack and its mitigation in this blog post: https://seemann.io/posts/2023-12-18-exploiting-quics-path-validation/\n\nThere's no way to mitigate this attack, please update quic-go to a version that contains the fix.","affected":[{"package":{"name":"github.com/quic-go/quic-go","ecosystem":"Go","purl":"pkg:golang/github.com/quic-go/quic-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.40.0"},{"fixed":"0.40.1"}]}],"versions":["0.40.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-ppxx-5m9h-6vxf/GHSA-ppxx-5m9h-6vxf.json"}},{"package":{"name":"github.com/quic-go/quic-go","ecosystem":"Go","purl":"pkg:golang/github.com/quic-go/quic-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.39.0"},{"fixed":"0.39.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-ppxx-5m9h-6vxf/GHSA-ppxx-5m9h-6vxf.json"}},{"package":{"name":"github.com/quic-go/quic-go","ecosystem":"Go","purl":"pkg:golang/github.com/quic-go/quic-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.38.0"},{"fixed":"0.38.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-ppxx-5m9h-6vxf/GHSA-ppxx-5m9h-6vxf.json"}},{"package":{"name":"github.com/quic-go/quic-go","ecosystem":"Go","purl":"pkg:golang/github.com/quic-go/quic-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.37.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-ppxx-5m9h-6vxf/GHSA-ppxx-5m9h-6vxf.json"}}],"references":[{"type":"WEB","url":"https://github.com/quic-go/quic-go/security/advisories/GHSA-ppxx-5m9h-6vxf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-49295"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/17fc98c2d81dbe685c19702dc694a9d606ac56dc"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/21609ddfeff93668c7625a85eb09f1541fdad965"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/3a9c18bcd27a01c551ac9bf8bd2b4bded77c189a"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/554d543b50b917369fb1394cc5396d928166cf49"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/6cc3d58935426191296171a6c0d1ee965e10534e"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/9aaefe19fc3dc8c8917cc87e6128bb56d9e9e6cc"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/a0ffa757499913f7be69aa78f573a6aee3430ae4"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/d7aa627ebde91cf799ada2a07443faa9b1e5abb8"},{"type":"PACKAGE","url":"https://github.com/quic-go/quic-go"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/G5RSHDTVMYAIGYVVFGKTMFHAZJMA3EVV"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZE7IOKXX5AATU2WR3V76X5Y3A44QAATG"},{"type":"WEB","url":"https://seemann.io/posts/2023-12-18-exploiting-quics-path-validation"}],"database_specific":{"cwe_ids":["CWE-400"],"github_reviewed":true,"github_reviewed_at":"2024-01-10T15:08:40Z","nvd_published_at":"2024-01-10T22:15:50Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:H"}]}
