{"id":"CVE-2022-31078","aliases":["GHSA-qpx3-9565-5xwm","GO-2022-0510"],"url":"https://o3.security/vulnerability/CVE-2022-31078","summary":"KubeEdge CloudCore Router memory exhaustion","details":"### Impact\nThe 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.\nOnly 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` as below.\n```\nmodules:\n  ...\n  router:\n    enable: true\n```\n\n### Patches\nThis bug has been fixed in Kubeedge 1.11.1, 1.10.2, 1.9.4. Users should update to these versions to resolve the issue.\n\n### Workarounds\nDisable the router module in the config file `cloudcore.yaml`.\n\n### References\nNA\n\n### Credits\nThanks David Korczynski and Adam Korczynski of ADA Logics for responsibly disclosing this issue in accordance with the [kubeedge security policy](https://github.com/kubeedge/kubeedge/security/policy) during a security audit sponsored by CNCF and facilitated by OSTIF.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [KubeEdge repo](https://github.com/kubeedge/kubeedge/issues/new/choose)\n* To make a vulnerability report, email your vulnerability to the private [cncf-kubeedge-security@lists.cncf.io](mailto:cncf-kubeedge-security@lists.cncf.io) list with the security details and the details expected for [KubeEdge bug reports](https://github.com/kubeedge/kubeedge/blob/master/.github/ISSUE_TEMPLATE/bug-report.md).\n","published":"2022-07-11T20:25:09Z","modified":"2026-10-28T02:30:26.213862804Z","cvss":{"score":4.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.11.1"},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.10.2"},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.9.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31078.json"},{"type":"ADVISORY","url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-qpx3-9565-5xwm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31078"},{"type":"PACKAGE","url":"https://github.com/kubeedge/kubeedge"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:26.213862804Z"}}
