EUVD-2025-2104

Comprehensive Technical Analysis of EUVD-2025-2104

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-2104 affects versions of the jsonpath-plus package before 10.3.0. It is classified as a Remote Code Execution (RCE) vulnerability due to improper input sanitization. The issue arises from the unsafe default usage of eval='safe' mode, which allows an attacker to execute arbitrary code on the system.

Severity Evaluation: The vulnerability has a base score of 9.3 according to CVSS 4.0, indicating a critical severity level. The score vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P highlights the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Authentication (AT): None (N)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality Impact (VC): High (H)
• Integrity Impact (VI): High (H)
• Availability Impact (VA): High (H)
• Scope Change (SC): None (N)
• Secondary Impact (SI): None (N)
• Secondary Availability (SA): None (N)
• Exploit Code Maturity (E): Proof-of-Concept (P)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant security breaches if exploited.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing physical access to the system.
• Web Applications: Applications that use the jsonpath-plus package to process user input are particularly at risk. An attacker can craft malicious input to trigger the RCE.

Exploitation Methods:

• Malicious Input: An attacker can send specially crafted input to the application, exploiting the improper input sanitization to execute arbitrary code.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable systems and exploit them en masse.

3. Affected Systems and Software Versions

Affected Software:

• jsonpath-plus versions before 10.3.0

Affected Systems:

• Any system or application that uses the vulnerable versions of the jsonpath-plus package. This includes web servers, cloud services, and any other environments where the package is deployed.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade to Safe Version: Upgrade to jsonpath-plus version 10.3.0 or later, which includes the fix for this vulnerability.
• Input Sanitization: Implement additional input sanitization and validation mechanisms to prevent malicious input from reaching the vulnerable code.
• Disable Unsafe Features: Ensure that the eval='safe' mode is disabled or properly secured.

Long-Term Mitigation:

• Regular Patching: Establish a regular patching and update schedule for all software dependencies.
• Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Use Security Tools: Employ static and dynamic analysis tools to detect and remediate vulnerabilities in the codebase.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• Organizations must comply with regulations such as GDPR, which mandate the protection of personal data. Failure to address this vulnerability could result in data breaches and subsequent legal consequences.

Economic Impact:

• The exploitation of this vulnerability can lead to significant financial losses due to data breaches, system downtime, and reputational damage.

Public Trust:

• Public trust in digital services can be severely impacted if such vulnerabilities are exploited, leading to a loss of confidence in online services and e-commerce platforms.

6. Technical Details for Security Professionals

Vulnerability Details:

• The vulnerability is caused by an incomplete fix for CVE-2024-21534, which also involved improper input sanitization.
• The specific issue lies in the Safe-Script.js file, particularly around line 127, where the eval='safe' mode is improperly handled.
