EUVD-2025-18870

Comprehensive Technical Analysis of EUVD-2025-18870

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability described in EUVD-2025-18870 allows a non-admin user to integrate a script into a report, which can later be executed on the BRAIN2 server with administrator rights. This poses a significant risk as it can lead to unauthorized code execution with elevated privileges.

Severity Evaluation: The vulnerability has a CVSS Base Score of 10.0, which is the highest possible score, indicating a critical severity. 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 (Network Vector): The vulnerability can be exploited remotely over the network.
• AC:L (Low Complexity): The attack requires low skill or resources to exploit.
• PR:N (No Privileges Required): No prior privileges are needed to exploit the vulnerability.
• UI:N (No User Interaction): The attack does not require any user interaction.
• S:C (Changed Scope): The vulnerability affects a different security scope.
• C:H (High Confidentiality Impact): The vulnerability allows for complete access to sensitive data.
• I:H (High Integrity Impact): The vulnerability allows for complete modification of system files or information.
• A:H (High Availability Impact): The vulnerability can lead to complete denial of service.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can inject malicious scripts into reports, which are then executed on the BRAIN2 server with administrator rights.
• Privilege Escalation: Non-admin users can escalate their privileges by exploiting this vulnerability, gaining unauthorized access to sensitive data and system controls.

Exploitation Methods:

• Script Injection: Attackers can craft reports with embedded scripts designed to execute malicious code on the BRAIN2 server.
• Phishing: Attackers may use social engineering techniques to trick non-admin users into generating and submitting malicious reports.

3. Affected Systems and Software Versions

Affected Systems:

• BRAIN2 server versions 0.0 to 3.06.

Vendor and Product Information:

• Vendor: Bizerba SE & Co. KG
• Product: BRAIN2

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest security patches provided by Bizerba SE & Co. KG.
• Access Control: Restrict report generation and submission capabilities to trusted users only.
