EUVD-2024-54295

Comprehensive Technical Analysis of EUVD-2024-54295

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-54295, also known as CVE-2024-45480, is classified as an improper control of generation of code ('Code Injection') vulnerability in the AprolCreateReport component of B&R APROL versions prior to 4.4-00P5. This vulnerability allows an unauthenticated network-based attacker to read files from the local system.

Severity Evaluation:

• Base Score: 9.2 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N

The high base score of 9.2 indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality Impact (VC): High (H)
• Scope Change (SC): High (H)

The vulnerability's critical nature stems from its potential to be exploited remotely without authentication, leading to significant confidentiality breaches.

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 over the network without needing physical access to the system.
• Unauthenticated Access: The attacker does not require any authentication to exploit this vulnerability, making it easier to target.

Exploitation Methods:

• Code Injection: The attacker can inject malicious code into the AprolCreateReport component, which may allow them to read sensitive files from the local system.
• File Reading: By exploiting the code injection vulnerability, the attacker can read files that may contain sensitive information, such as configuration files, logs, or even proprietary data.

3. Affected Systems and Software Versions

Affected Systems:

• B&R APROL: Versions prior to 4.4-00P5

Vendor:

• B&R Industrial Automation

Organizations using B&R APROL versions below 4.4-00P5 are at risk and should prioritize updating their systems to mitigate this vulnerability.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Software: Upgrade to B&R APROL version 4.4-00P5 or later, which includes the necessary patches to address this vulnerability.
• Network Segmentation: Implement network segmentation to isolate critical systems and reduce the attack surface.
• Firewall Rules: Configure firewalls to restrict access to the AprolCreateReport component, allowing only trusted sources.
• Monitoring: Enhance monitoring and logging to detect any suspicious activities related to the AprolCreateReport component.

Long-Term Strategies:

• Regular Patch Management: Establish a robust patch management process to ensure timely updates and patches for all software.
• Security Training: Conduct regular security training for staff to recognize and respond to potential threats.
• Incident Response Plan: Develop and maintain an incident response plan to quickly address any security breaches.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations, particularly those in the industrial automation sector. The potential for unauthenticated network-based attacks to read sensitive files can lead to data breaches, intellectual property theft, and disruption of industrial processes. This underscores the need for robust cybersecurity measures and continuous monitoring in critical infrastructure sectors.

6. Technical Details for Security Professionals

Vulnerability Details:

• Component: AprolCreateReport
• Vulnerability Type: Code Injection
