This vulnerability exists within the MRCMS 3.1.3 content management system where a cross site scripting flaw has been identified in the administrative user management functionality. The specific component affected is the Edit User Page located at /admin/user/edit.do which processes user input through the Username parameter. The vulnerability classification indicates a problematic condition that allows malicious actors to inject malicious scripts into the web application's user interface. This represents a significant security risk as it enables unauthorized code execution within the context of affected user sessions.
The technical flaw manifests through improper input validation and output encoding within the application's user management interface. When a user submits a Username parameter through the edit.do endpoint, the application fails to properly sanitize or escape the input before rendering it back to the browser. This allows an attacker to inject malicious javascript code that will execute in the browser of any user who views the affected page. The vulnerability specifically targets the Username field which suggests the application does not adequately filter or encode user-supplied data before displaying it in the web interface, creating an opportunity for persistent or reflected cross site scripting attacks.
The operational impact of this vulnerability is substantial as it enables remote code execution within the context of authenticated user sessions. Attackers can leverage this flaw to steal session cookies, redirect users to malicious websites, modify content, or perform actions on behalf of legitimate users. The fact that the exploit has been publicly disclosed increases the risk profile significantly, as it provides threat actors with ready-made attack vectors. This vulnerability compromises the integrity of the administrative interface and could potentially allow attackers to escalate privileges, modify user permissions, or gain unauthorized access to sensitive system information.
The vulnerability aligns with CWE-79 which specifically addresses cross site scripting flaws in web applications, and maps to ATT&CK technique T1566.001 for initial access through spearphishing attachments or links. Organizations using MRCMS 3.1.3 should immediately implement input validation measures including strict sanitization of all user inputs, output encoding for all dynamic content, and proper parameter validation. Mitigation strategies should include implementing content security policies, conducting thorough input validation at both client and server levels, and applying the latest security patches from the vendor. Regular security testing including web application penetration testing and vulnerability scanning should be conducted to identify similar issues in other components of the system. Additionally, implementing web application firewalls and monitoring for suspicious input patterns can help detect and prevent exploitation attempts.
