CVE-2026-29120Public exploit

Root escalation via crackable hardcoded password hash

Published Mar 4, 2026 · Updated Mar 4, 2026

Use of hard-coded credentials in the SFX2100 SuperFlex Satellite Receiver allows local users to escalate privileges to root. The world-readable /root/anaconda-ks.cfg file exposes a reused root password hash that is weak enough for an offline dictionary attack. Direct root SSH login is disabled, so exploitation requires existing low-privileged device access; the recovered password grants full root control.
