CVE-2021-3020: 
NixOS vulnerability analysis and mitigation

Overview

An issue was discovered in ClusterLabs Hawk (aka HA Web Konsole) through 2.3.0-15. It ships the binary hawk_invoke (built from tools/hawk_invoke.c), intended to provide privileged access for web operations (NVD).

Technical details

The vulnerability exists in the hawk_invoke binary component of ClusterLabs Hawk, which is used to provide privileged access for web operations. The issue was addressed by removing the hawk_invoke binary and replacing it with a more secure command execution method using capture3 for running system commands instead of the runas construct (GitHub).

Impact

The vulnerability could potentially allow unauthorized privileged access through the web interface, affecting the security of the HA Web Konsole system (NVD).

Mitigation and workarounds

The issue has been fixed in subsequent releases by removing the hawk_invoke binary and implementing a more secure command execution method. The fix includes using capture3 for running system commands instead of the runas construct, removing unnecessary chmods, and sanitizing filename handling during hb_report uploads in the GUI (GitHub).
