AnalysisAIv1 – Mar 12, 2026

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.

Technical ContextAI · show details

Classified as CWE-269 (Improper Privilege Management). Affects Sfx2100 Firmware. 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.

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.

Executive ViewAI

Why It Matters

The IDC SFX2100 Satellite Receiver contains a file system permissions vulnerability that could allow unauthorized access to sensitive monitoring data and system configurations. Organizations operating this equipment face potential data exposure and operational disruption, particularly if multiple devices are deployed across critical infrastructure.

Business Impact: High

Compensating Controls

Implement strict network access controls and firewall rules limiting connectivity to SFX2100 devices to trusted management networks only. Disable unnecessary user accounts and enforce strong authentication mechanisms. Deploy file integrity monitoring on affected devices to detect unauthorized access. Consider physical network isolation of non-critical devices pending patch availability. Implement enhanced logging and SIEM alerting for monitor user directory access.
