Zurmo 3.2.3 allows XSS via the latitude or longitude parameter to maps/default/mapAndPoint.
Zurmo 3.2.3 is vulnerable to a Cross-Site Scripting (XSS) attack, allowing attackers to inject malicious scripts into the application. This can lead to session hijacking, data theft, and website defacement, potentially compromising sensitive user information and system integrity.
The vulnerability stems from insufficient input validation and output encoding within the maps/default/mapAndPoint functionality of Zurmo 3.2.3. Specifically, the application fails to properly sanitize user-supplied input provided through the latitude or longitude parameters before rendering it within the web page. This allows an attacker to inject arbitrary JavaScript code, which is then executed by the victim's browser. The lack of proper input validation and output encoding (e.g., HTML escaping) is the root cause, allowing for the execution of malicious scripts.
While no specific APTs are directly linked to this CVE, XSS vulnerabilities are commonly exploited by various threat actors for initial access, credential harvesting, and lateral movement. This vulnerability could be leveraged in conjunction with other exploits. CISA KEV: Not Listed
Web Application Firewall (WAF) logs showing suspicious HTTP requests containing JavaScript payloads in the latitude or longitude parameters.
Network traffic analysis revealing unusual HTTP requests to the maps/default/mapAndPoint endpoint with potentially malicious content.
Server-side logs indicating the injection of JavaScript code into the application's response.
Security Information and Event Management (SIEM) systems configured to detect XSS attempts based on known patterns and signatures.
Upgrade to a patched version of Zurmo or a version that addresses the XSS vulnerability. Check the vendor's website for available patches.
Implement robust input validation to sanitize all user-supplied data, specifically the latitude and longitude parameters, ensuring that only expected data types and formats are accepted.
Implement output encoding (e.g., HTML escaping) to prevent the execution of malicious scripts within the HTML response. This ensures that any injected JavaScript is treated as plain text.
Use a Web Application Firewall (WAF) to filter malicious requests before they reach the application. Configure the WAF to detect and block XSS attempts.
Regularly scan the application for vulnerabilities using automated security tools.
Implement a Content Security Policy (CSP) to restrict the sources from which the browser can load resources, mitigating the impact of XSS attacks.
