CVE-2024-32746 is a cross-site scripting (XSS) vulnerability identified in WonderCMS version 3.4.3, specifically within the Settings section's Menu module. The vulnerability arises from improper sanitization or validation of user input in the MENU parameter, allowing an attacker with limited privileges to inject crafted payloads containing arbitrary web scripts or HTML. This injection can lead to execution of malicious scripts in the context of the victim's browser when the affected page is viewed. The vulnerability requires user interaction, such as an authenticated user accessing the manipulated menu settings, which limits its exploitation scope. The CVSS 3.1 base score is 4.6, reflecting network attack vector, low attack complexity, required privileges, and user interaction. The impact primarily affects integrity and availability, as attackers can manipulate the web interface or cause disruptions, but confidentiality is not directly compromised. No patches or known exploits are currently available, indicating the need for proactive mitigation. The weakness corresponds to CWE-80, a common XSS category, emphasizing the need for input validation and output encoding in web applications. WonderCMS is a lightweight content management system, often used by small to medium websites, making this vulnerability relevant to organizations relying on this platform for web content management.

The primary impact of CVE-2024-32746 is the potential for attackers to execute arbitrary scripts within the context of authenticated users, which can lead to several adverse effects. These include manipulation of the web interface, defacement, injection of malicious content, or disruption of service availability. Although confidentiality is not directly affected, the XSS vulnerability can be leveraged for session hijacking, phishing, or delivering further malware payloads, escalating the threat. Organizations using WonderCMS for their websites or intranet portals may face reputational damage, loss of user trust, and operational disruptions if exploited. Since exploitation requires limited privileges and user interaction, insider threats or social engineering could facilitate attacks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future exploitation. The medium severity score reflects moderate risk, but organizations with sensitive web content or high traffic should treat this vulnerability seriously to prevent compromise.

To mitigate CVE-2024-32746, organizations should first verify if they are running WonderCMS version 3.4.3 or earlier and monitor for official patches or updates from the WonderCMS development team. In the absence of an official patch, administrators should implement strict input validation and output encoding on the MENU parameter within the Menu module to prevent injection of malicious scripts. Employing a web application firewall (WAF) with rules targeting XSS payloads can provide an additional layer of defense. Restricting access to the Settings section to trusted administrators and enforcing strong authentication reduces the risk of exploitation. Regularly auditing and sanitizing user inputs in the CMS and educating administrators about the risks of clicking on untrusted links or payloads can further reduce attack vectors. Monitoring web server logs for unusual activity related to the MENU parameter may help detect attempted exploitation. Finally, consider isolating the CMS environment or using content security policies (CSP) to limit the impact of any injected scripts.
