DescriptionCVE.org

The installer of FinalCode Client provided by Digital Arts Inc. contains an incorrect default permissions vulnerability. A non-administrative user may execute arbitrary code with SYSTEM privilege.

Executive ViewAI

Why It Matters

FinalCode Client installations across the organization are vulnerable to privilege escalation due to improper file permissions set during installation. An attacker with local system access could exploit this to gain elevated privileges, potentially compromising sensitive data or system integrity. Immediate action is required to assess exposure and implement interim protections while awaiting a vendor patch.

Business Impact: High

Compensating Controls

Restrict FinalCode Client installation directories with minimal necessary permissions (remove world-readable/writable access); implement file integrity monitoring on FinalCode binaries and configuration files; isolate FinalCode Client systems from sensitive network segments where possible; enforce principle of least privilege for user accounts running FinalCode; enable audit logging for privilege escalation attempts; consider temporary uninstall of FinalCode Client on non-critical systems until patch is available.

Attack Technique

Privilege Escalation HIGH

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

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
