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`.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-07-11 21:15:00","updated_at":"2023-07-21 17:07:00"},"problem_types":["CWE-770"],"metrics":[],"references":[{"url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-qpx3-9565-5xwm","name":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-qpx3-9565-5xwm","refsource":"CONFIRM","tags":[],"title":"CloudCore Router: Large HTTP response can exhaust memory in REST handler · Advisory · kubeedge/kubeedge · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-31078","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31078","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"31078","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"linuxfoundation","cpe5":"kubeedge","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-31078","STATE":"PUBLIC","TITLE":"KubeEdge CloudCore Router memory exhaustion"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"kubeedge","version":{"version_data":[{"version_value":"< 1.9.4"},{"version_value":">= 1.10.0, < 1.10.2"},{"version_value":"= 1.11.0"}]}}]},"vendor_name":"kubeedge"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge.
