EUVD-2025-203826

Comprehensive Technical Analysis of EUVD-2025-203826

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-203826 pertains to Apache Commons Text versions prior to 1.10.0. The interpolation features in these versions can be exploited when untrusted input is passed into the text-substitution API. This can lead to remote code execution (RCE), allowing attackers to execute arbitrary commands or access external resources.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the potential for remote code execution, which can result in complete system compromise. The CVSS vector highlights that the attack can be executed over the network (AV:N), requires low complexity (AC:L), does not need privileges (PR:N) or user interaction (UI:N), and has a high impact on confidentiality, integrity, and availability (C:H/I:H/A:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Untrusted Input: Applications that pass untrusted input into the text-substitution API of Apache Commons Text are at risk. This can occur through user input fields, file uploads, or any other means where user-controlled data is processed.
• Remote Code Execution: Attackers can craft input that triggers interpolators to execute commands or access external resources, leading to RCE.

Exploitation Methods:

• Command Injection: By injecting malicious commands into the input, attackers can execute arbitrary code on the server.
• Resource Access: Attackers can manipulate the 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
• FileMaker Server versions prior to 22.0.4

Affected Systems:

• Any system running the vulnerable versions of Apache Commons Text or FileMaker Server.
• Systems that integrate with these libraries and pass untrusted input into the text-substitution API.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update Software: Upgrade to Apache Commons Text version 1.10.0 or later and FileMaker Server version 22.0.4 or later.
• Input Validation: Implement robust input validation and sanitization to ensure that untrusted input does not reach the text-substitution API.
• Access Controls: Restrict access to the text-substitution API to trusted sources only.

Long-Term Mitigation:

• Security Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
• Patch Management: Establish a rigorous patch management process to ensure timely updates of all software components.
• Security Training: Provide training for developers and administrators on secure coding practices and input handling.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations that rely on Apache Commons Text or FileMaker Server. Given the critical nature of the vulnerability, it could lead to widespread exploitation if not addressed promptly. Organizations in sectors such as finance, healthcare, and government are particularly at risk due to the sensitive nature of the data they handle.

Regulatory Compliance:

• Organizations must ensure compliance with regulations such as GDPR, which mandates robust security measures to protect personal data.
• Failure to address this vulnerability could result in data breaches, leading to regulatory penalties and reputational damage.

6. Technical Details for Security Professionals

Vulnerability Details:

• CVE ID: CVE-2025-46295
• GHSA ID: GHSA-9gm8-6rq9-qj6f
• Assigner: Apple
• ENISA ID Product: FileMaker Server (unspecified <22.0.4)
• ENISA ID Vendor: Claris

Technical Recommendations:

• Code Review: Conduct a thorough code review to identify all instances where untrusted input is passed to the text-substitution API.
• Monitoring: Implement monitoring and logging to detect any suspicious activities related to the text-substitution API.
• Incident Response: Prepare an incident response plan to quickly address any potential exploitation of this vulnerability.
