The vulnerability identified as CVE-2018-19810 represents a cross site scripting flaw within InfoVista VistaPortal SE Version 5.1, specifically manifesting in the GroupMove.jsp management console page. This reflected cross site scripting vulnerability occurs when user-supplied input values are not properly sanitized before being returned to the web browser in the HTTP response. The affected parameters include ConnPoolName, GroupId, and type, which when manipulated can inject malicious script code into the web application's response. This vulnerability falls under CWE-79 which categorizes improper neutralization of input during web page generation, making it a classic reflected XSS attack vector.
The technical exploitation of this vulnerability requires an attacker to craft malicious URLs containing script payloads that are then submitted to the vulnerable GroupMove.jsp page. When a victim clicks on such a crafted link or when the application processes these parameters in its response, the malicious script executes within the victim's browser context. The reflected nature of this vulnerability means that the malicious script is not stored on the server but rather reflected off the web application in response to a user request, making it particularly dangerous for targeted attacks. The vulnerability exists in the management console environment which typically requires elevated privileges, potentially allowing attackers to escalate their access within the system.
The operational impact of this vulnerability extends beyond simple script execution as it can be leveraged for session hijacking, credential theft, or redirection to malicious sites. Attackers could exploit this vulnerability to steal administrator sessions, manipulate data within the management console, or gain unauthorized access to sensitive system information. The fact that this vulnerability resides in a management console component significantly increases its risk profile since it provides access to administrative functions and potentially sensitive configuration data. This vulnerability can also serve as a stepping stone for more sophisticated attacks targeting the underlying infrastructure.
Mitigation strategies for CVE-2018-19810 should focus on implementing proper input validation and output encoding mechanisms within the web application. The most effective approach involves sanitizing all user-supplied input parameters before they are processed or returned in HTTP responses, particularly for parameters ConnPoolName, GroupId, and type. Implementing Content Security Policy headers can provide additional protection against script execution. The application should employ proper HTML encoding of output data to prevent script injection. Organizations should also consider implementing web application firewalls and regular security scanning to detect similar vulnerabilities. This vulnerability aligns with ATT&CK technique T1203 which describes exploiting web applications for privilege escalation, and T1566 which covers social engineering through malicious links. Patch management procedures should be established to ensure timely updates of InfoVista VistaPortal SE to versions that address this reflected XSS vulnerability.
