FKIE_CVE-2026-28775

Vulnerability from fkie_nvd - Published: 2026-03-04 08:16 - Updated: 2026-06-17 10:29
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.
