How to Fix CVE-2022-31078

To remediate this vulnerability, upgrade all affected Github.com/kubeedge/kubeedge dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/kubeedge/kubeedge fixed: 1.11.1
Upgrade github.com/kubeedge/kubeedge to 1.11.1
github.com/kubeedge/kubeedge fixed: 1.10.2
Upgrade github.com/kubeedge/kubeedge to 1.10.2
github.com/kubeedge/kubeedge fixed: 1.9.4
Upgrade github.com/kubeedge/kubeedge to 1.9.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/kubeedge/kubeedge

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-31078, inspect your project dependencies for Github.com/kubeedge/kubeedge:

inspect dependencies for github.com/kubeedge/kubeedge

Analyze the terminal output to locate any version of Github.com/kubeedge/kubeedge in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/kubeedge/kubeedge, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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` as below. ``` modules: ... router: enable: true ``` ### Patches This 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. ### Workarounds Disable the router module in the config file `cloudcore.yaml`. ### References NA ### Credits Thanks 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. ### For more information If you have any questions or comments about this advisory: * Open an issue in [KubeEdge repo](https://github.com/kubeedge/kubeedge/issues/new/choose) * 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).
