CVE-2026-29121 Details
Description
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.
A vulnerability exists in the International Data Casting (IDC) SFX2100 satellite receiver, where the '/sbin/ip' utility is installed with the setuid bit enabled. This configuration allows any local user to execute the binary with elevated privileges. Exploitation of this vulnerability can lead to unauthorized access to privileged files on the local file system, such as '/etc/shadow', and may open up additional avenues for performing privileged actions. The issue arises from the improper handling of user input in the 'IPaddr' parameter of the '/IDC_Ping/main.cgi' script, which is vulnerable to OS command injection. This exploitation can be achieved by injecting commands that are executed with root privileges.
