CyberRota Analysis

AI-Generated

The vulnerability arises in Calico's shared debug server, which, when enabled, allows kube-controllers and Goldmane components to expose their Go pprof debug listener on 0.0.0.0 without authentication. This configuration can lead to unauthorized access to sensitive information, such as process heap and goroutine stacks, from any pod with network access to the listener. Organizations using Calico should prioritize addressing this issue, especially those with the debug server enabled, to mitigate potential data exposure risks.

Original NVD Description

When Calico's shared debug server is enabled (disabled by default), the Calico kube-controllers and Goldmane components bind their Go pprof debug listener to 0.0.0.0 without authentication. Any pod with network reachability to the listener can retrieve the process heap, goroutine stacks (including function arguments), and command-line arguments. Depending on the process's in-memory state, the heap may contain sensitive material. The debug listener is opt-in but is unsafe when enabled because it offers no authentication and no safe localhost-only binding option.
