CVE-2024-50462 identifies a stored cross-site scripting vulnerability in the html5maps Interactive World Map product, affecting all versions up to and including 3.4.4. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and stored persistently within the application. When other users access the affected pages, the malicious scripts execute in their browsers under the context of the vulnerable site. This can lead to theft of sensitive information such as cookies, session tokens, or credentials, as well as unauthorized actions performed on behalf of the victim user. The vulnerability does not require authentication or complex user interaction beyond visiting the compromised page, increasing its exploitability. Although no public exploits have been reported yet, the nature of stored XSS makes it a critical concern for web applications that embed the Interactive World Map component. The vulnerability affects organizations that use this product in their web infrastructure, particularly those providing interactive geographic data visualization services. The lack of an official patch at the time of publication necessitates interim mitigations such as rigorous input validation, output encoding, and Content Security Policy (CSP) enforcement to reduce risk. The vulnerability highlights the importance of secure coding practices in web components that process user input and generate dynamic content.

The impact of CVE-2024-50462 is significant for organizations using the html5maps Interactive World Map on their websites. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of the vulnerable site, compromising user confidentiality by stealing session cookies, credentials, or other sensitive data. Integrity may be affected if attackers manipulate displayed content or perform unauthorized actions on behalf of users. Availability could also be impacted if attackers use the vulnerability to inject disruptive scripts or conduct further attacks such as phishing or malware distribution. Given that the vulnerability is stored XSS, the malicious payload persists and can affect multiple users over time, increasing the attack surface. Organizations with high web traffic or those serving sensitive user bases face elevated risks including reputational damage, regulatory penalties, and loss of user trust. The absence of a patch at the time of disclosure increases exposure, making timely mitigation critical. Additionally, attackers could use this vulnerability as a foothold for more advanced attacks within the victim environment.

To mitigate CVE-2024-50462, organizations should prioritize applying official patches from the html5maps vendor once they become available. Until then, implement strict input validation on all user-supplied data to ensure that potentially malicious scripts or HTML tags are sanitized or rejected before storage or rendering. Employ robust output encoding techniques, such as HTML entity encoding, when displaying user input on web pages to prevent script execution. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. Regularly audit and monitor web application logs for suspicious input patterns or anomalous behavior indicative of exploitation attempts. Consider isolating the Interactive World Map component within sandboxed iframes to limit script execution scope. Educate developers on secure coding practices to prevent similar vulnerabilities in future releases. Finally, conduct penetration testing and code reviews focused on input handling and output generation to identify and remediate related weaknesses.
