CVE-2025-50739

Comprehensive Technical Analysis of CVE-2025-50739

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-50739 CISA Vulnerability Name: CVE-2025-50739 Description: iib0011 omni-tools v0.4.0 is vulnerable to remote code execution (RCE) via unsafe JSON deserialization. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for remote code execution, which can lead to complete system compromise. The vulnerability allows an attacker to execute arbitrary code on the affected system, posing a significant risk to the confidentiality, integrity, and availability of the system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: An attacker can send specially crafted JSON payloads over the network to exploit the vulnerability.
• Web-Based Attacks: If the omni-tools application is exposed via a web interface, an attacker can exploit the vulnerability through HTTP requests containing malicious JSON data.

Exploitation Methods:

• Unsafe JSON Deserialization: The attacker can craft a JSON payload that, when deserialized, executes arbitrary code on the server. This can be achieved by including malicious objects or references within the JSON structure.
• Payload Injection: The attacker can inject code into the JSON payload that, upon deserialization, triggers the execution of the injected code.

3. Affected Systems and Software Versions

Affected Software:

• iib0011 omni-tools v0.4.0

Affected Systems:

• Any system running the vulnerable version of omni-tools.
• Systems that process JSON data from untrusted sources without proper validation and sanitization.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Upgrade to a patched version of omni-tools as soon as it becomes available.
• Input Validation: Implement strict input validation and sanitization for all JSON data processed by the application.
• Deserialization Libraries: Use secure deserialization libraries that do not allow the execution of arbitrary code.

Long-Term Mitigation:

• Code Review: Conduct a thorough code review to identify and fix other potential deserialization vulnerabilities.
• Security Training: Provide training to developers on secure coding practices, especially regarding deserialization and input validation.
• Regular Updates: Ensure that all software components are regularly updated to the latest versions to mitigate known vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-50739 highlights the ongoing risk of deserialization vulnerabilities in modern applications. This type of vulnerability can lead to severe security breaches, including data theft, system compromise, and unauthorized access. The high CVSS score underscores the critical nature of this vulnerability and the need for robust security measures to prevent such issues.

6. Technical Details for Security Professionals

Vulnerability Details:

• Root Cause: The vulnerability arises from the unsafe deserialization of JSON data, which allows an attacker to inject and execute arbitrary code.
• Exploitation: The attacker can craft a JSON payload that includes malicious objects or references. Upon deserialization, these objects trigger the execution of the injected code.

Detection and Response:

• Monitoring: Implement monitoring for unusual network traffic patterns and suspicious JSON payloads.
• Logging: Enable detailed logging for deserialization processes to detect and respond to potential exploitation attempts.
• Incident Response: Develop an incident response plan that includes steps for identifying, containing, and remediating deserialization-based attacks.

Example Exploit:

{
  "type": "com.example.ExploitClass",
  "command": "rm -rf /"
}

In this example, the JSON payload includes a reference to a class (ExploitClass) that, when deserialized, executes the rm -rf / command, leading to a critical system compromise.

Conclusion: CVE-2025-50739 represents a significant risk to systems running the vulnerable version of omni-tools. Immediate mitigation strategies, including patching and input validation, are essential to protect against potential exploitation. Long-term measures, such as code reviews and security training, are crucial for preventing similar vulnerabilities in the future. The cybersecurity landscape must continue to evolve to address the persistent threat of deserialization vulnerabilities.
