Overview
CVE-2024-8528 details a reflected Cross-Site Scripting (XSS) vulnerability discovered in Automated Logic WebCTRL and Carrier i-VU systems. This vulnerability arises from the insufficient sanitization of a specific GET parameter, allowing attackers to inject and execute malicious JavaScript code within the context of a user’s browser. Successful exploitation can lead to session hijacking, credential theft, and defacement of the application.
This vulnerability was published on 2025-11-19T14:15:57.780.
Technical Details
The reflected XSS vulnerability in Automated Logic WebCTRL and Carrier i-VU stems from a lack of proper input validation and sanitization on a specific GET parameter. By crafting a malicious URL containing JavaScript code within the vulnerable parameter, an attacker can trick a user into clicking the link. When the user visits the crafted URL, the injected script will be reflected back to the user’s browser and executed. The exact parameter vulnerable to XSS is not publicly available outside of a penetration testing report. However, this weakness is enough to understand the core issue.
The lack of input validation allows the injected JavaScript to bypass security measures and potentially gain access to sensitive information or perform unauthorized actions on behalf of the user. This can be especially dangerous in building automation systems, where compromised accounts can allow attackers to modify building settings (temperature, lighting, access control), cause physical damage, or gather intelligence on building occupants.
CVSS Analysis
Currently, the CVSS score and severity for CVE-2024-8528 are listed as N/A (Not Available). A CVSS score would typically assess the impact and exploitability of the vulnerability, helping organizations prioritize patching efforts. Once a CVSS score is assigned, it will provide a more concrete understanding of the risk posed by this vulnerability. Given the sensitive nature of building automation systems and the potential for significant impact, it is crucial to apply the necessary mitigations immediately.
Possible Impact
Exploitation of this reflected XSS vulnerability can have severe consequences:
- Session Hijacking: Attackers can steal user session cookies and impersonate legitimate users.
- Credential Theft: Malicious scripts can capture user credentials (usernames and passwords) entered on affected pages.
- Defacement: The application’s interface can be modified to display misleading or harmful content.
- Building Automation Compromise: Access to the building automation system can be leveraged to manipulate HVAC systems, lighting, security systems, and other critical building functions.
- Phishing: Attackers can redirect users to phishing sites designed to steal credentials for other services.
Mitigation and Patch Steps
To mitigate the risk associated with CVE-2024-8528, the following steps should be taken:
- Apply the official patch: Carrier and Automated Logic have likely released a patch to address this vulnerability. Download and install the latest version of WebCTRL and i-VU from the vendor’s website. Refer to the official security advisory for detailed patching instructions.
- Input Validation and Sanitization: Implement robust input validation and sanitization techniques to prevent XSS attacks. All user-supplied data should be validated and sanitized before being displayed or used in the application.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests, including those attempting to exploit XSS vulnerabilities. Configure the WAF to specifically look for XSS attack patterns.
- User Awareness Training: Educate users about the risks of clicking on suspicious links and attachments. Teach them to recognize phishing attempts and avoid entering sensitive information on untrusted websites.
- Regular Security Audits: Conduct regular security audits and penetration tests to identify and address vulnerabilities in the application and infrastructure.
