Kerentanan External Control of File Name or Path. Skor CVSS 3.1 8.4 (High) menurut github.com.

Deskripsi (NVD)

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.
