CVE-2025-51387

Comprehensive Technical Analysis of CVE-2025-51387

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-51387 CVSS Score: 9.8

The vulnerability in GitKraken Desktop versions 10.8.0 and 11.1.0 is classified as a code injection vulnerability due to misconfigured Electron Fuses. The CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact if exploited. The misconfigurations include enabling RunAsNode and not disabling EnableNodeCliInspectArguments, which allow the application to run in Node.js mode and accept arbitrary arguments, leading to arbitrary code execution.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Exploitation: An attacker with local access to the system can exploit the vulnerability by passing malicious arguments to the application, leading to arbitrary code execution.
• Remote Exploitation: If the application processes untrusted input from remote sources (e.g., via a web interface or remote file), an attacker could craft malicious input to achieve code execution.

Exploitation Methods:

• Command Injection: By leveraging the enabled RunAsNode setting, an attacker can inject Node.js commands.
• Inspection Arguments: The lack of disabling EnableNodeCliInspectArguments allows attackers to pass inspection arguments, which can be used to execute arbitrary code.

3. Affected Systems and Software Versions

Affected Software:

• GitKraken Desktop versions 10.8.0 and 11.1.0

Affected Systems:

• Any system running the vulnerable versions of GitKraken Desktop, including Windows, macOS, and Linux.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Disable RunAsNode: Ensure that the RunAsNode setting is disabled to prevent the application from running in Node.js mode.
• Disable EnableNodeCliInspectArguments: Ensure that EnableNodeCliInspectArguments is disabled to prevent the passing of inspection arguments.

Long-Term Mitigation:

• Update to a Patched Version: Upgrade to a version of GitKraken Desktop that addresses this vulnerability.
• Input Validation: Implement strict input validation to prevent the execution of malicious commands.
• Least Privilege: Run the application with the least privileges necessary to minimize the impact of a successful exploit.

5. Impact on Cybersecurity Landscape

The discovery of this vulnerability highlights the importance of secure configuration management in Electron-based applications. Misconfigurations in Electron Fuses can lead to severe security issues, underscoring the need for thorough security audits and adherence to best practices. This vulnerability serves as a reminder for developers to carefully review and configure security settings, especially in applications that handle sensitive data or have a wide user base.

6. Technical Details for Security Professionals

Electron Fuses Configuration:

• RunAsNode: This setting allows the application to run in Node.js mode, which can be exploited to execute arbitrary code.
• EnableNodeCliInspectArguments: This setting allows the passing of inspection arguments, which can be used to inject malicious code.

Detection and Monitoring:

• Log Analysis: Monitor application logs for unusual activity, such as unexpected command executions or inspection arguments.
• Behavioral Analysis: Implement behavioral analysis tools to detect anomalous behavior that may indicate an exploitation attempt.
