CVE-2024-2097 in MACH SCM
Summary
by MITRE • 03/27/2024
Authenticated List control client can execute the LINQ query in SCM Server to present event as list for operator. An authenticated malicious client can send special LINQ query to execute arbitrary code remotely (RCE) on the SCM Server that an attacker otherwise does not have authorization to do.

The vulnerability identified as CVE-2024-2097 represents a critical remote code execution flaw within SCM Server's list control functionality. This vulnerability arises from insufficient input validation and sanitization within the authentication-based client interface that processes LINQ queries for event presentation. The flaw exists in the server's handling of user-provided query parameters that are directly translated into executable LINQ expressions without proper security controls.
The technical implementation of this vulnerability stems from the server's trust model that allows authenticated users to construct and submit LINQ expressions through the list control interface. When a malicious authenticated client submits specially crafted LINQ queries, the server processes these expressions without adequate filtering or sandboxing mechanisms. This design flaw enables attackers to inject arbitrary code that executes within the context of the SCM Server's privileged process, bypassing normal authorization controls that would otherwise prevent such operations.
From an operational perspective, this vulnerability creates a severe risk for organizations relying on SCM Server for configuration management and automation. The authenticated nature of the attack means that an attacker must first obtain valid credentials, but once achieved, they can execute arbitrary commands with the privileges of the SCM Server process. This could lead to complete system compromise, data exfiltration, or disruption of critical configuration management services. The vulnerability affects the confidentiality, integrity, and availability of the entire SCM infrastructure.
The impact of CVE-2024-2097 aligns with CWE-94, which describes "Improper Control of Generation of Code ('Code Injection')" and maps to ATT&CK technique T1059.001 for command and scripting interpreter. Organizations using SCM Server should implement immediate mitigations including input validation, query parameter sanitization, and limiting the scope of authenticated client privileges. Network segmentation and monitoring for unusual LINQ query patterns can help detect exploitation attempts. The vulnerability demonstrates the critical importance of secure coding practices when handling user-supplied data in server-side applications, particularly when translating such data into executable code or query languages.
