{"id":"CVE-2022-31080","summary":"KubeEdge Websocket Client in package Viaduct: DoS from large response message","details":"KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, a large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body. The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. The software is affected If users who are authenticated to the edge side connect to `cloudhub` from the edge side through WebSocket protocol. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There are currently no known workarounds.","aliases":["GHSA-6wvc-6pww-qr4r","GO-2022-0512"],"modified":"2026-08-12T03:51:28.364962269Z","published":"2022-07-11T20:55:09Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-400"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31080.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31080.json"},{"type":"ADVISORY","url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-6wvc-6pww-qr4r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31080"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kubeedge/kubeedge","events":[{"introduced":"0"},{"fixed":"ecca82fd5d0b0891dbd562f4d4349443d958b9df"},{"introduced":"3803951602f938d9d90d74957eb0fbc238142101"},{"fixed":"27a6957ee7685884a7d9b3d87c13f61625cb3bc9"},{"introduced":"24b146e19e8b8d9171851673ff60162711ac71c9"},{"fixed":"6ccb68fae799d210d9f304df9cba210c492432a7"}],"database_specific":{"cpe":"cpe:2.3:a:linuxfoundation:kubeedge:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.9.4"},{"introduced":"1.10.0"},{"fixed":"1.10.2"},{"introduced":"1.11.0"},{"fixed":"1.11.1"}],"source":"CPE_RANGE"}}],"versions":["= 1.11.0","v1.10.1","v1.9.3","v1.11.0","v1.9.2","v1.10.0","v1.9.1","v1.9.0-beta.0","v1.9.0","v1.8.0-beta.0","v1.7.0-beta.0","v1.7.0","v1.6.0-beta.0","v1.5.0-beta.0","v1.4.0-beta.0","v1.4.0-alpha.0","v1.3.0","v1.3.0-beta.0","v1.3.0-alpha.0","v1.2.0-beta.0","v1.1.0-beta.0","v1.0.0","v0.3.0-beta.0","v0.2.1","v0.2","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-31080.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H"}]}
