How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-28224, inspect your project dependencies for Github.com/projectcalico/calico:

inspect dependencies for github.com/projectcalico/calico

Analyze the terminal output to locate any version of Github.com/projectcalico/calico in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.22.2), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/projectcalico/calico, 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

Clusters using Calico (version 3.22.1 and below), Calico Enterprise (version 3.12.0 and below), may be vulnerable to route hijacking with the floating IP feature. Due to insufficient validation, a privileged attacker may be able to set a floating IP annotation to a pod even if the feature is not enabled. This may allow the attacker to intercept and reroute traffic to their compromised pod.
