CVE-2020-37017 in CodeMeter
Summary
by MITRE • 01/29/2026
CodeMeter 6.60 contains an unquoted service path vulnerability that allows local users to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted binary path in the CodeMeter Runtime Server service to inject malicious code that would execute with LocalSystem permissions.

The CodeMeter 6.60 software presents a critical unquoted service path vulnerability that fundamentally compromises system security through improper service configuration. This flaw exists within the CodeMeter Runtime Server service where the binary path is not properly quoted, creating an exploitable condition that allows local attackers to place malicious executables in directories along the system path. The vulnerability stems from the service configuration where the executable path contains spaces but lacks proper quotation marks, enabling path traversal attacks that can lead to privilege escalation. According to the Common Weakness Enumeration framework, this represents a CWE-16: Configuration weakness, specifically manifesting as an improper path quoting scenario that directly enables malicious code injection. The attack vector requires local system access and leverages the principle of least privilege violation by allowing arbitrary code execution with LocalSystem permissions, which provides complete control over the affected system.
The technical exploitation of this vulnerability occurs when an attacker places a malicious executable in a directory that appears before the legitimate CodeMeter service binary in the system PATH environment variable. When the service restarts or is triggered, the system attempts to execute the binary from the unquoted path, inadvertently executing the attacker-controlled file instead of the intended legitimate service executable. This behavior aligns with the ATT&CK framework's technique T1036.004: Masquerading - Valid Code Signing, where attackers leverage legitimate system processes to execute malicious code. The vulnerability affects systems running CodeMeter 6.60 and earlier versions, making it particularly dangerous in enterprise environments where multiple systems may be running the vulnerable software. The service path typically includes directories such as program files or system folders where attackers can place malicious binaries without requiring elevated permissions for initial placement, though the final execution will occur with elevated privileges due to the LocalSystem context of the service.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it provides attackers with persistent access to the compromised system and enables further lateral movement within network environments. Once executed with LocalSystem privileges, the malicious code can modify system files, install additional malware, create backdoors, or exfiltrate sensitive data from the compromised system. The vulnerability's local nature means that attackers do not require network access or complex remote exploitation techniques, making it particularly dangerous in environments where physical access or initial compromise is possible. Organizations running affected versions of CodeMeter software face significant risk of complete system compromise, especially when the service runs with elevated privileges. The vulnerability also affects the integrity of the system's security posture by undermining the principle of defense in depth, as the legitimate service can be replaced or augmented with malicious code that executes with the highest system privileges. Security professionals should consider this vulnerability as part of their comprehensive vulnerability management programs, particularly in environments where CodeMeter software is deployed and where local privilege escalation risks are not adequately mitigated through other controls.
Mitigation strategies for this vulnerability should focus on immediate service path remediation through proper quotation of binary paths, ensuring that all service executable paths are enclosed in quotation marks to prevent path traversal attacks. System administrators should conduct thorough inventory assessments to identify all instances of CodeMeter 6.60 and similar vulnerable software installations across the enterprise environment. The recommended approach includes updating to the latest version of CodeMeter software where the service path has been properly quoted, or manually correcting the service configuration by modifying the service binary path to include proper quotation marks around the executable location. Additionally, implementing strict access controls and privilege management can limit the impact of potential exploitation, though the most effective mitigation remains the correction of the underlying service configuration issue. Organizations should also consider implementing application whitelisting policies that restrict execution of unauthorized binaries in critical system directories. Regular security audits and vulnerability assessments should include checks for unquoted service paths as part of standard security compliance procedures, ensuring that similar configuration weaknesses are identified and remediated before they can be exploited by malicious actors. The vulnerability serves as a reminder of the importance of proper service configuration management and the critical role that seemingly minor configuration issues can play in system security breaches.
