1. Risk Assessment
The vulnerability identified as CVE-2024-5622 is an untrusted search path issue in the AprolConfigureCCServices component of B&R APROL systems, affecting versions <= R 4.2-07P3 and <= R 4.4-00P3. This flaw allows an authenticated local attacker to execute arbitrary code with elevated privileges, posing a significant risk to the confidentiality, integrity, and availability of the affected systems. The CVSS v4.0 base score of 7.3 (HIGH) underscores the severity of this vulnerability.
The likelihood of exploitation is moderate, as it requires local access and low privileges, but the impact is severe. Attackers could gain full control over the system, leading to potential data breaches, system manipulation, or disruption of critical operations. The vulnerability is particularly concerning in industrial automation environments, where such systems often control critical infrastructure. The ease of exploitation is relatively low, given the straightforward nature of untrusted search path vulnerabilities, which can be exploited by placing malicious files in specific directories.
2. Potential Attack Scenarios
An attacker with local access to a vulnerable B&R APROL system could exploit this vulnerability by placing a malicious executable in a directory that is searched by the AprolConfigureCCServices component. When the service attempts to load a legitimate file, it could instead execute the attacker's malicious code due to the untrusted search path.
The attack process would involve the following steps:
- The attacker gains local access to the system, either through legitimate credentials or by exploiting another vulnerability.
- The attacker identifies the directories searched by AprolConfigureCCServices and places a malicious executable in one of these directories.
- The attacker triggers the service to execute, causing it to load the malicious file instead of the intended legitimate file.
- The malicious code executes with elevated privileges, allowing the attacker to take full control of the system, exfiltrate sensitive data, or disrupt operations.
The potential outcomes include unauthorized access to sensitive information, system compromise, and operational downtime, which could have severe financial and reputational consequences for the organization.
3. Mitigation Recommendations
Immediate action is required to mitigate this vulnerability. Organizations using affected versions of B&R APROL should apply the latest patches provided by B&R Industrial Automation. The vendor has released a security advisory detailing the vulnerability and providing guidance on remediation.
Additionally, organizations should implement the following measures:
- Restrict local access to critical systems to only authorized personnel.
- Monitor and audit file system activity for unusual or unauthorized changes.
- Implement strict access controls and privilege management to limit the impact of potential exploits.
- Regularly update and patch all software components to address known vulnerabilities.

1. Risk Assessment
The vulnerability identified as CVE-2024-5623 is an untrusted search path issue in B&R APROL versions up to and including R 4.4-00P3. This flaw allows an authenticated local attacker to manipulate the search path, potentially leading to the execution of arbitrary code under the privileges of other users. The CVSS v4.0 base score of 5.4 (MEDIUM severity) indicates a moderate risk, with high impacts on confidentiality, integrity, and availability if exploited. The attack complexity is low, and the privileges required are also low, making it relatively easy for an attacker with local access to exploit this vulnerability. The business impact could be significant, as successful exploitation could lead to unauthorized access, data breaches, or disruption of industrial automation systems. The likelihood of exploitation is moderate, given the need for local access and low privileges, but the potential consequences are severe.
2. Potential Attack Scenarios
An attacker with authenticated local access to a system running B&R APROL could exploit this vulnerability by placing a malicious executable in a directory that is part of the untrusted search path. When another user with higher privileges executes a legitimate application, the system may inadvertently load and execute the malicious file instead. This could allow the attacker to escalate privileges, gain unauthorized access to sensitive data, or disrupt critical industrial processes. For example, in an industrial automation environment, an attacker could compromise a system controlling manufacturing equipment, leading to production downtime or safety hazards. The attack vector is local, requiring the attacker to have some level of access to the target system, but the passive user interaction requirement means that the victim may not even realize their actions are being exploited.
3. Mitigation Recommendations
The primary mitigation for this vulnerability is to apply the latest security patches provided by B&R Industrial Automation. Organizations should immediately update their B&R APROL systems to a version beyond R 4.4-00P3. Additionally, restrict local access to systems running B&R APROL to only trusted personnel and implement strict privilege management to minimize the risk of privilege escalation. Regularly monitor and audit system activity for signs of unauthorized access or suspicious behavior. For further guidance, refer to the vendor's security advisory at https://www.br-automation.com/fileadmin/SA24P2014_Multiple_vulnerabilities_in_BR_APROL.pdf-367290ae.pdf.
4. Executive Summary
CVE-2024-5623 is a medium-severity vulnerability in B&R APROL systems that could allow authenticated local attackers to execute arbitrary code under the privileges of other users. This poses a significant risk to industrial automation environments, potentially leading to unauthorized access, data breaches, or operational disruptions. The vulnerability is relatively easy to exploit, requiring only low privileges and local access. Immediate action is recommended, including applying the latest patches from B&R Industrial Automation and restricting access to affected systems. Addressing this vulnerability is critical to maintaining the security and reliability of industrial automation processes and preventing potential business impacts.

1. Risk Assessment
The vulnerability identified as CVE-2024-5624 is a Reflected Cross-Site Scripting (XSS) issue in the Shift Logbook application of B&R APROL systems, specifically affecting versions <= R 4.4-00P3. This vulnerability allows a network-based attacker to execute arbitrary JavaScript code within the context of a user's browser session. The nature of this vulnerability lies in improper neutralization of user-supplied input during web page generation, classified under CWE-79.
The likelihood of exploitation is moderate, given the low attack complexity and the fact that no privileges are required to exploit the vulnerability. However, user interaction is necessary, which slightly reduces the ease of exploitation. The potential business impact includes compromised user sessions, unauthorized actions performed on behalf of the user, and potential data exfiltration. While the confidentiality and integrity impacts are rated as low, the availability impact is negligible. The EPSS score of 0.000460000 indicates a relatively low probability of exploitation in the wild.
2. Potential Attack Scenarios
An attacker could craft a malicious URL containing JavaScript code and trick a user into clicking it, such as through a phishing email or a malicious link on a website. When the user accesses the Shift Logbook application via the malicious URL, the application reflects the injected script back to the user's browser, executing it in the context of their session.
For example, an attacker could embed a script that steals session cookies or authentication tokens, allowing them to hijack the user's session. Alternatively, the script could modify the content of the web page, leading to defacement or the injection of malicious forms to capture sensitive user input. The outcome could range from unauthorized access to sensitive data to the manipulation of application functionality, depending on the privileges of the compromised user.
3. Mitigation Recommendations
The primary mitigation for this vulnerability is to apply the latest patch or update provided by B&R Industrial Automation for the APROL system. Users should upgrade to a version beyond R 4.4-00P3 to resolve the issue.
In the interim, organizations should implement input validation and output encoding to neutralize potentially malicious input. Web Application Firewalls (WAFs) can be deployed to detect and block XSS attempts. Additionally, users should be educated about the risks of clicking on untrusted links and encouraged to report suspicious activity.
