CVE-2004-1714 in BlackICE PC Protection
Summary
by MITRE
BlackICE PC Protection and Server Protection installs (1) firewall.ini, (2) blackice.ini, (3) sigs.ini and (4) protect.ini with Everyone Full Control permissions, which allows local users to cause a denial of service (crash) or modify configuration, as demonstrated by modifying firewall.ini to contain a large firewall rule.

This vulnerability resides in BlackICE PC Protection and Server Protection software versions from 2004, representing a critical privilege escalation and configuration manipulation flaw. The issue stems from the software's installation process which creates four critical configuration files - firewall.ini, blackice.ini, sigs.ini, and protect.ini - with overly permissive Everyone Full Control permissions. This design flaw fundamentally violates the principle of least privilege, allowing any local user to gain unrestricted access to the security software's core configuration mechanisms. The vulnerability is classified under CWE-276, which specifically addresses incorrect permissions for critical resources, and aligns with ATT&CK technique T1068, involving local privilege escalation through improper access controls. The flaw demonstrates how security software itself can become a vector for exploitation when proper access controls are not implemented during installation.
The technical execution of this vulnerability involves a straightforward local attack vector where malicious users can modify any of the four configuration files with complete administrative privileges. When an attacker modifies firewall.ini to contain excessively large firewall rules, the system experiences crashes or denial of service conditions, effectively disabling the security protection mechanisms. This demonstrates the cascading impact of poor file permissions, where a single misconfiguration in the installation process creates multiple attack surfaces. The vulnerability exploits the fundamental assumption that security software configuration files should be protected from unauthorized modification, yet the software installer grants universal write access to these critical components. The impact extends beyond simple service disruption to potential complete compromise of the security posture, as attackers can modify signature files, protection rules, and core configuration parameters.
The operational impact of this vulnerability is severe for any organization relying on BlackICE protection, as it fundamentally undermines the integrity of the security infrastructure. Local users can not only cause system crashes but also modify protection rules to bypass security measures or create backdoors within the firewall configuration. This creates a scenario where legitimate security software becomes a liability rather than a protection mechanism. Organizations may experience complete loss of network protection capabilities, with attackers able to manipulate the firewall rules to allow malicious traffic while blocking legitimate security scanning or monitoring activities. The vulnerability's persistence means that even after system restarts or reboots, the insecure permissions remain in place, creating ongoing exposure windows. This issue particularly affects enterprise environments where multiple users have local access to protected systems.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. The immediate solution involves manually correcting file permissions on the four vulnerable configuration files to restrict access to only authorized administrative users and system processes. Organizations should implement automated configuration management tools to enforce proper access controls and monitor for unauthorized permission changes. System administrators must conduct comprehensive audits of installed security software to identify similar permission issues across other security tools. The vulnerability highlights the necessity of implementing mandatory access controls and privilege separation within security software installations, aligning with security standards such as NIST SP 800-53 and ISO 27001 requirements for secure configuration management. Regular security assessments should include verification of file permissions and access control mechanisms to prevent similar issues from emerging in other software components.
