CVE-2008-0366 in CORE FORCE
Summary
by MITRE
CORE FORCE before 0.95.172 does not properly validate arguments to SSDT hook handler functions in the Registry module, which allows local users to cause a denial of service (system crash) and possibly execute arbitrary code in the kernel context via crafted arguments.

The vulnerability identified as CVE-2008-0366 affects CORE FORCE software versions prior to 0.95.172, specifically within the Registry module where SSDT hook handler functions are implemented. This represents a critical security flaw that stems from inadequate input validation mechanisms within kernel-level code. The vulnerability occurs when the system processes crafted arguments passed to SSDT hook handlers, creating a condition where malicious input can trigger unexpected behavior in the kernel space. The improper argument validation creates a path for exploitation that can result in system instability and potential code execution privileges.
The technical nature of this vulnerability aligns with CWE-20, which describes improper input validation, and CWE-119, which addresses insufficient protection of data in memory. The flaw exists in the kernel context where SSDT (System Service Descriptor Table) hooks are utilized to intercept and modify system calls. When the Registry module fails to properly validate arguments passed to these hook handlers, it creates an opportunity for attackers to manipulate the execution flow. The vulnerability allows local users to craft specific inputs that cause the system to crash or potentially execute arbitrary code with kernel privileges. This represents a classic buffer overflow scenario where insufficient validation leads to memory corruption and privilege escalation possibilities.
The operational impact of this vulnerability extends beyond simple denial of service conditions. While system crashes represent the primary immediate consequence, the potential for arbitrary code execution in kernel context poses significant risks to overall system security. Attackers with local access can leverage this vulnerability to gain elevated privileges, potentially compromising the entire system. The kernel-level execution context means that successful exploitation could allow attackers to bypass standard security controls, modify system files, install malware, or establish persistent backdoors. This vulnerability effectively undermines the fundamental security model of the operating system by providing a pathway for privilege escalation from user-level to kernel-level access.
Mitigation strategies for CVE-2008-0366 should prioritize immediate software updates to CORE FORCE version 0.95.172 or later, which contains the necessary patches to address the argument validation issues. System administrators should implement comprehensive monitoring for unusual system behavior or crash patterns that might indicate exploitation attempts. The vulnerability demonstrates the importance of proper input validation in kernel space code and aligns with ATT&CK technique T1068, which covers local privilege escalation. Organizations should also consider implementing additional security controls such as kernel patch management, system integrity monitoring, and regular security assessments to prevent similar vulnerabilities from being exploited. The remediation process should include thorough testing of the updated software to ensure that the patch does not introduce compatibility issues while effectively addressing the core validation flaws.
