An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-31078 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-2022-31078/ (Markdown: https://insights.sbomify.com/CVE-2022-31078/index.md)","id":"CVE-2022-31078","markdown":"https://insights.sbomify.com/CVE-2022-31078/index.md","name":"CVE-2022-31078","record":{"aliases":["GHSA-qpx3-9565-5xwm","GO-2022-0510"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"KubeEdge CloudCore","requires_auth":"high_privilege","summary":"An authenticated attacker can cause CloudCore denial of service by triggering memory exhaustion via large HTTP responses in the router module.","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, the CloudCore Router does not impose a limit on the size of responses to requests made by the REST handler. An attacker could use this weakness to make a request that will return an HTTP response with a large body and cause DoS of CloudCore. In the HTTP Handler API, the rest handler makes a request to a pre-specified handle. The handle will return an HTTP response that is then read into memory. The consequence of the exhaustion is that CloudCore will be in a denial of service. Only an authenticated user of the cloud can make an attack. It will be affected only when users enable `router` module in the config file `cloudcore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the router switch in the config file `cloudcore.yaml`.","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 CloudCore Router memory exhaustion","id":"CVE-2022-31078","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":"KubeEdge Cloud Stream and Edge Stream DoS from large stream message","id":"CVE-2022-31079"},"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-2022-0510"},{"ecosystem":"Go","fixed":["1.9.4"],"introduced":["0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-qpx3-9565-5xwm"},{"ecosystem":"Go","fixed":["1.9.4"],"introduced":["0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","source":"GHSA-qpx3-9565-5xwm"},{"ecosystem":"Go","fixed":["1.10.2"],"introduced":["1.10.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-qpx3-9565-5xwm"},{"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-qpx3-9565-5xwm"},{"ecosystem":"Go","fixed":["1.11.1"],"introduced":["1.11.0"],"last_affected":[],"package":"github.com/kubeedge/kubeedge","purl":null,"source":"GHSA-qpx3-9565-5xwm"},{"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-qpx3-9565-5xwm"}],"prev":{"headline":"Malicious response from KubeEdge can crash CSI Driver controller server","id":"CVE-2022-31077"},"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 Cloud Stream and Edge Stream DoS from large stream message","id":"CVE-2022-31079","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":4.4,"headline":"KubeEdge Websocket Client in package Viaduct: DoS from large response message","id":"CVE-2022-31080","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 authenticated attacker can cause CloudCore denial of service by triggering memory exhaustion via large HTTP responses in the router module.","url":"https://insights.sbomify.com/CVE-2022-31078/"}
