HIGH 7.8

DescriptionCVE.org

International Data Casting (IDC) SFX2100 satellite receiver comes with the /sbin/ip utility installed with the setuid bit set. This configuration grants elevated privileges to any local user who can execute the binary. A local actor is able to use the GTFObins resource to preform privileged file reads as the root user on the local file system and may potentially lead to other avenues for preforming privileged actions.

AnalysisAI

The setuid bit on the /sbin/ip utility in IDC SFX2100 satellite receiver firmware allows local users to execute privileged operations as root, enabling unauthorized file reads and potential privilege escalation attacks. Public exploit code exists for this vulnerability, and affected users have no available patch. This vulnerability impacts any local user with access to the device.
