DescriptionCVE.org

A SUID root-owned binary in /home/xd/terminal/XDTerminal in International Data Casting (IDC) SFX2100 on Linux allows a local actor to potentially preform local privilege escalation depending on conditions of the system via execution of the affected SUID binary. This can be via PATH hijacking, symlink abuse or shared object hijacking.

Executive ViewAI

Why It Matters

A local privilege escalation vulnerability in IDC SFX2100 Linux systems could allow authenticated users to gain root-level access, potentially compromising system integrity and sensitive data. This poses an immediate risk to organizations running affected equipment, particularly in critical infrastructure environments where the SFX2100 is deployed.

Business Impact: High
Compensating Controls

Remove SUID bit from /home/xd/terminal/XDTerminal binary (chmod u-s /home/xd/terminal/XDTerminal); Restrict local shell access via PAM/SSH configuration to authorized administrators only; Implement file integrity monitoring on the vulnerable binary; Use AppArmor or SELinux profiles to restrict XDTerminal execution context; Segment affected systems on isolated networks with limited local user access; Monitor for suspicious privilege escalation attempts via auditd logging.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
