The SNMP daemon runs as root and uses a net\u2011snmp version prior to 5.8 that accepts NET\u2011SNMP\u2011EXTEND\u2011MIB commands.

The exploit probability is reported as less than one percent, suggesting the vulnerable configuration is uncommon or not widely exploited yet, but the absence from a known exploited vulnerability catalog does not diminish the risk for a network that can reach the device. The likely attack vector is remote SNMP over the network; no authentication or complex prerequisites are required beyond network connectivity to the SNMP service. If exploitation occurs, the attacker would gain root privileges and could execute any command, set up persistence, or tamper with satellite reception functions."}}}}, "created": "2026-03-04T21:03:59.474169+00:00", "updated": "2026-04-17T13:15:19.694488+00:00", "vendors": ["international_datacasting_corporation_(idc)", "international_datacasting_corporation_(idc)$PRODUCT$sfx2100_series_superflex_satellitereceiver"]}
