Vulnerability from github – Published: 2026-03-04 09:31 – Updated: 2026-03-05 06:30

Details

An unauthenticated Remote Code Execution (RCE) vulnerability exists in the SNMP service of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver. The deployment insecurely provisions the private SNMP community string with read/write access by default. Because the SNMP agent runs as root, an unauthenticated remote attacker can utilize NET-SNMP-EXTEND-MIB directives, abusing the fact that the system runs a vulnerable version of net-snmp pre 5.8, to execute arbitrary operating system commands with root privileges.

Severity ?

10.0 (Critical)
