EUVD-2025-7721

Comprehensive Technical Analysis of EUVD-2025-7721

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-7721, also known as CVE-2025-26936, is classified as an "Improper Control of Generation of Code ('Code Injection')" vulnerability in the NotFound Fresh Framework. This vulnerability allows for Code Injection, which can lead to unauthenticated remote code execution (RCE). The severity of this vulnerability is rated with a CVSS Base Score of 10.0, the highest possible score, indicating a critical risk.

The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• AV:N - Attack Vector: Network, meaning the vulnerability is exploitable over the network.
• AC:L - Attack Complexity: Low, indicating that the attack is relatively easy to execute.
• PR:N - Privileges Required: None, meaning no privileges are required to exploit the vulnerability.
• UI:N - User Interaction: None, indicating that no user interaction is required.
• S:C - Scope: Changed, meaning the vulnerability affects a component that is outside the security scope of the vulnerable component.
• C:H - Confidentiality: High, indicating a complete loss of confidentiality.
• I:H - Integrity: High, indicating a complete loss of integrity.
• A:H - Availability: High, indicating a complete loss of availability.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Network-Based Attacks: Since the attack vector is network-based, attackers can exploit this vulnerability remotely without needing physical access to the system.
• Code Injection: Attackers can inject malicious code into the Fresh Framework, leading to RCE. This can be done through crafted HTTP requests or other network-based interactions.
• Unauthenticated Access: The vulnerability allows for unauthenticated exploitation, meaning attackers do not need valid credentials to exploit the system.

Exploitation methods may involve:

• Crafted HTTP Requests: Sending specially crafted HTTP requests to the vulnerable endpoint.
• Automated Scripts: Using automated scripts to scan for and exploit the vulnerability across multiple targets.
• Malicious Payloads: Injecting malicious payloads that can execute arbitrary code on the server.

3. Affected Systems and Software Versions

The vulnerability affects the Fresh Framework from version n/a through 1.70.0. This means all versions up to and including 1.70.0 are vulnerable. Organizations using these versions are at risk and should take immediate action to mitigate the threat.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Immediately apply the latest patches or updates provided by the vendor, NotFound. Ensure that the Fresh Framework is updated to a version higher than 1.70.0.
• Network Segmentation: Implement network segmentation to isolate vulnerable systems and reduce the attack surface.
• Access Controls: Enforce strict access controls and monitor network traffic for suspicious activities.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on any unusual or malicious network activities.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security gaps.

5. Impact on European Cybersecurity Landscape

The high severity of this vulnerability poses a significant risk to the European cybersecurity landscape. Organizations across various sectors, including government, healthcare, finance, and critical infrastructure, may be affected. The potential for unauthenticated RCE can lead to data breaches, service disruptions, and financial losses. It is crucial for European cybersecurity authorities and organizations to prioritize the mitigation of this vulnerability to protect against potential cyber threats.
