CyberRota Analysis
AI-GeneratedThe ndsudo helper command in Netdata versions prior to 2.10.4 is vulnerable due to improper handling of a caller-controlled socket path, allowing low-privileged netdata service accounts to direct root fail2ban-client to a malicious UNIX socket. This flaw can lead to the execution of attacker-controlled code with root privileges, posing a significant risk to systems running fail2ban-client. Organizations utilizing Netdata should prioritize upgrading to version 2.10.4 or later to mitigate this high-severity vulnerability.

Original NVD Description
Netdata is an open source observability tool. Prior to 2.10.4, the setuid-root ndsudo helper command fail2ban-client-status-socket in src/collectors/utils/ndsudo.c accepts a caller-controlled --socket_path from the low-privileged netdata service account. The account can direct root fail2ban-client to a malicious UNIX socket, and fail2ban/client/csocket.py CSocket.receive() passes the returned data to pickle.loads(), allowing attacker-controlled code to execute as root on systems with fail2ban-client installed. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.
