CVE-2025-46295

Comprehensive Technical Analysis of CVE-2025-46295

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-46295 CVSS Score: 9.8

The vulnerability in Apache Commons Text versions prior to 1.10.0 is critical, as indicated by its high CVSS score of 9.8. This score reflects the potential for remote code execution (RCE), which is one of the most severe types of vulnerabilities due to its potential to allow attackers to execute arbitrary commands on the affected system.

2. Potential Attack Vectors and Exploitation Methods

The vulnerability arises from the interpolation features in Apache Commons Text, which can be abused when untrusted input is passed into the text-substitution API. Specifically, certain interpolators can trigger actions such as executing commands or accessing external resources. An attacker could exploit this by:

• Injecting Malicious Input: Crafting input that, when processed by the interpolation features, triggers the execution of arbitrary commands.
• Exploiting External Resource Access: Manipulating input to access external resources, potentially leading to data exfiltration or further exploitation.

3. Affected Systems and Software Versions

• Affected Software: Apache Commons Text versions prior to 1.10.0.
• Affected Systems: Any system or application that uses the vulnerable versions of Apache Commons Text, including but not limited to FileMaker Server versions prior to 22.0.4.

4. Recommended Mitigation Strategies

1. Upgrade to Safe Versions:

   • Upgrade Apache Commons Text to version 1.10.0 or later.
   • Upgrade FileMaker Server to version 22.0.4 or later.

2. Input Validation and Sanitization:

   • Ensure that all input passed to the text-substitution API is properly validated and sanitized to prevent injection attacks.

3. Least Privilege Principle:

   • Run applications with the minimum necessary privileges to limit the impact of potential exploitation.

4. Network Segmentation:

   • Implement network segmentation to isolate critical systems and reduce the attack surface.

5. Regular Security Audits:

   • Conduct regular security audits and vulnerability assessments to identify and mitigate similar vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of this vulnerability highlight the importance of secure coding practices and the need for robust input validation mechanisms. It underscores the potential risks associated with third-party libraries and the necessity for organizations to maintain up-to-date software versions. The high CVSS score indicates the significant risk posed by this vulnerability, emphasizing the need for immediate remediation.

6. Technical Details for Security Professionals

Vulnerability Details:

• The interpolation features in Apache Commons Text allow for dynamic text substitution, which can be manipulated to execute commands or access external resources.
• The vulnerability is triggered when untrusted input is passed into the text-substitution API, leading to potential RCE.

Detection and Monitoring:

• Implement logging and monitoring to detect unusual activities such as unexpected command executions or external resource access.
• Use intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor for suspicious network traffic.

Patch Management:

• Ensure that patch management processes are in place to quickly apply updates and patches for critical vulnerabilities.
• Regularly review and update third-party libraries and dependencies to mitigate risks associated with outdated software.

Incident Response:

• Develop and maintain an incident response plan that includes steps for identifying, containing, and remediating vulnerabilities like CVE-2025-46295.
• Conduct regular incident response drills to ensure readiness in case of an exploitation attempt.

Conclusion: CVE-2025-46295 represents a significant risk to systems using vulnerable versions of Apache Commons Text. Immediate action is required to upgrade affected software and implement robust security measures to prevent exploitation. The high CVSS score underscores the urgency and importance of addressing this vulnerability promptly.
