This cross site scripting vulnerability resides within InfoVista VistaPortal SE Version 5.1 build 51029 and specifically affects the management console interface. The flaw manifests in the UserPopupAddNewProp.jsp page where the ConnPoolName parameter is not properly sanitized or encoded before being reflected back to the user in the HTTP response. This represents a classic reflected cross site scripting vulnerability that falls under CWE-79 which defines improper neutralization of input during web page generation. The vulnerability allows an attacker to inject malicious scripts that execute in the victim's browser context when the page is loaded, potentially enabling session hijacking, credential theft, or redirection to malicious sites.
The operational impact of this vulnerability is significant as it provides attackers with a direct vector to compromise user sessions within the VistaPortal management environment. An attacker could craft a malicious URL containing script payloads in the ConnPoolName parameter and deliver it via phishing emails, social engineering, or by compromising other systems within the same network. When an authenticated user clicks the malicious link, the injected scripts execute in their browser session, potentially allowing the attacker to steal session cookies, modify user permissions, or access sensitive administrative functions. This vulnerability directly aligns with attack techniques described in the MITRE ATT&CK framework under T1059 for command and control communication and T1531 for credential access through session hijacking.
The technical implementation of this vulnerability demonstrates poor input validation practices within the web application's parameter handling mechanism. The ConnPoolName parameter is directly incorporated into the page response without proper HTML encoding or output sanitization, creating an environment where malicious script content can be executed. This flaw indicates a lack of comprehensive security testing during development and insufficient application security controls. Organizations should implement strict input validation, output encoding, and Content Security Policy headers to prevent such vulnerabilities. The vulnerability also highlights the importance of regular security assessments and penetration testing to identify reflected XSS flaws in web applications, particularly in management interfaces where elevated privileges may be available. Proper remediation requires implementing proper parameter validation, input sanitization, and output encoding mechanisms to prevent malicious content from being executed in user browsers.
