Attack profile from CVSS 4.0 · CNA. Fix status from CNA and GitHub. Impact type from CWE-284.
Summary
The CTFer.io Monitoring component is in charge of the collection, process and storage of various signals (i.e. logs, metrics and distributed traces). Prior to 0.2.1, due to a mis-written NetworkPolicy, a malicious actor can pivot from a component to any other namespace. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. This vulnerability is fixed in 0.2.1.
