EUVD-2025-6154

Comprehensive Technical Analysis of EUVD-2025-6154

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-6154 affects Volt, a functional API for Livewire. It allows for remote code execution (RCE) through maliciously crafted request payloads. This vulnerability is particularly severe because it can be exploited remotely without requiring any special privileges or user interaction.

Severity Evaluation: The CVSS (Common Vulnerability Scoring System) base score of 9.3 indicates a critical vulnerability. The vector string 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 breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low.
• AT:N (None): No special authentication is required.
• PR:N (None): No privileges are required.
• UI:N (None): No user interaction is required.
• VC:H (High): Confidentiality impact is high.
• VI:H (High): Integrity impact is high.
• VA:H (High): Availability impact is high.
• SC:N (None): Scope change is none.
• SI:N (None): Scope integrity is none.
• SA:N (None): Scope availability is none.

This combination of factors makes the vulnerability highly critical, as it can lead to significant damage if exploited.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the AV:N attribute, attackers can exploit this vulnerability over the network, making it accessible to a wide range of potential attackers.
• Crafted Payloads: Attackers can craft specific request payloads designed to exploit the vulnerability in Volt components, leading to RCE.

Exploitation Methods:

• Payload Injection: Attackers can inject malicious code into the request payloads, which the vulnerable Volt components will execute.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable systems and exploit them en masse.

3. Affected Systems and Software Versions

Affected Systems:

• Any system running Volt versions prior to 1.7.0.

Software Versions:

• Volt versions < 1.7.0 are vulnerable.
• The vulnerability is fixed in Volt version 1.7.0 and later.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Immediately upgrade to Volt version 1.7.0 or later.
• Patch Management: Ensure that all systems are regularly updated and patched.
• Network Segmentation: Implement network segmentation to limit the spread of potential attacks.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• Intrusion Detection: Deploy intrusion detection systems (IDS) to monitor for suspicious activity.
• Security Training: Provide training for developers and administrators on secure coding practices and vulnerability management.

5. Impact on European Cybersecurity Landscape

Regional Impact:

• Critical Infrastructure: Organizations using Volt in critical infrastructure could face significant risks if the vulnerability is exploited.
• Data Protection: The high confidentiality, integrity, and availability impacts could lead to data breaches and service disruptions, affecting compliance with regulations such as GDPR.
• Economic Impact: Businesses relying on Volt could face financial losses due to downtime, data breaches, and potential legal consequences.

Regulatory Compliance:

• GDPR: Organizations must ensure they comply with GDPR by protecting personal data and reporting breaches promptly.
• NIS Directive: Critical infrastructure providers must adhere to the Network and Information Systems (NIS) Directive to ensure resilience against cyber threats.

6. Technical Details for Security Professionals

Technical Overview:

• Vulnerability Type: Remote Code Execution (RCE)
• Exploit Mechanism: Malicious request payloads can trigger RCE in Volt components.
• Mitigation: Upgrade to Volt version 1.7.0 or later.
