An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-31080 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/kubeedge/kubeedge (Go): affected all versions; fixed in 1.9.4, 1.10.2, 1.11.1\n- github.com/kubeedge/kubeedge (Go): affected all versions; fixed in 1.9.4\n- github.com/kubeedge/kubeedge (Go): affected all versions; fixed in 1.9.4\n- github.com/kubeedge/kubeedge (Go): affected from 1.10.0; fixed in 1.10.2\n- github.com/kubeedge/kubeedge (Go): affected from 1.10.0; fixed in 1.10.2\n- github.com/kubeedge/kubeedge (Go): affected from 1.11.0; fixed in 1.11.1\n- github.com/kubeedge/kubeedge (Go): affected from 1.11.0; fixed in 1.11.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-31080/ (Markdown: https://insights.sbomify.com/CVE-2022-31080/index.md)","id":"CVE-2022-31080","markdown":"https://insights.sbomify.com/CVE-2022-31080/index.md","name":"CVE-2022-31080","record":{"aliases":["GHSA-6wvc-6pww-qr4r","GO-2022-0512"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"KubeEdge edge computing","requires_auth":"high_privilege","summary":"An attacker can cause a denial of service via memory exhaustion by sending large WebSocket responses to the KubeEdge viaduct client.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kubeedge","vendor":"linuxfoundation"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"KubeEdge Websocket Client in package Viaduct: DoS from large response message","id":"CVE-2022-31080","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":7,"n_references":1,"next":{"headline":"Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') in HTTP::Daemon","id":"CVE-2022-31081"},"packages":[{"ecosystem":"Go","fixed":["1.9.4","1.10.2","1.11.1"],"introduced":["0","1.10.0","1.11.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","source":"GO-2022-0512"},{"ecosystem":"Go","fixed":["1.9.4"],"introduced":["0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-6wvc-6pww-qr4r"},{"ecosystem":"Go","fixed":["1.9.4"],"introduced":["0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","source":"GHSA-6wvc-6pww-qr4r"},{"ecosystem":"Go","fixed":["1.10.2"],"introduced":["1.10.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-6wvc-6pww-qr4r"},{"ecosystem":"Go","fixed":["1.10.2"],"introduced":["1.10.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","source":"GHSA-6wvc-6pww-qr4r"},{"ecosystem":"Go","fixed":["1.11.1"],"introduced":["1.11.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-6wvc-6pww-qr4r"},{"ecosystem":"Go","fixed":["1.11.1"],"introduced":["1.11.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","source":"GHSA-6wvc-6pww-qr4r"}],"prev":{"headline":"KubeEdge Cloud Stream and Edge Stream DoS from large stream message","id":"CVE-2022-31079"},"products":["kubeedge"],"published":"2022-07-11","related":[{"cvss_score":6.5,"headline":"KubeEdge Edge ServiceBus module DoS","id":"CVE-2022-31073","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.9,"headline":"KubeEdge DoS when signing the CSR from EdgeCore","id":"CVE-2022-31075","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.5,"headline":"KubeEdge Cloud AdmissionController component DoS","id":"CVE-2022-31074","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.4,"headline":"KubeEdge CloudCore Router memory exhaustion","id":"CVE-2022-31078","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.4,"headline":"KubeEdge Cloud Stream and Edge Stream DoS from large stream message","id":"CVE-2022-31079","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.2,"headline":"Malicious Message can crash CloudCore in KubeEdge","id":"CVE-2022-31076","kev_date_added":null,"published":"2022-06-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["kubeedge"]},"summary":"An attacker can cause a denial of service via memory exhaustion by sending large WebSocket responses to the KubeEdge viaduct client.","url":"https://insights.sbomify.com/CVE-2022-31080/"}
