HIGH 7.8

DescriptionCVE.org

The IDC SFX2100 Satellite Receiver sets overly permissive file system permissions on the monitor user's home directory. The directory is configured with permissions 0777, granting read, write, and execute access to all local users on the system, which may cause local privilege escalation depending on conditions of the system due to the presence of highly privileged processes and binaries residing within the affected directory.

AnalysisAI

Local privilege escalation in IDC SFX2100 Satellite Receiver firmware occurs due to overly permissive file system permissions (0777) on a privileged user's home directory, allowing any local user to read, write, and execute files within it. An attacker with local access can leverage highly privileged processes and binaries in this directory to escalate their privileges on the system. Public exploit code exists for this vulnerability, and no patch is currently available.
