IBM InfoSphere Information Server version 11.7 contains a cross-site scripting vulnerability that represents a critical security weakness in the web-based user interface. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, where the application fails to properly validate and sanitize user input before rendering it in web pages. The flaw enables attackers to inject malicious JavaScript code through input fields or parameters that are subsequently executed in the context of other users' browsers who view the affected pages.
The technical implementation of this vulnerability occurs when the web application does not adequately escape or filter user-supplied data before incorporating it into dynamic web content. This allows an attacker to craft malicious payloads that exploit the lack of input validation controls. When legitimate users interact with the affected interface, their browsers execute the injected JavaScript code, potentially compromising the integrity of their sessions and the confidentiality of their credentials.
The operational impact of this vulnerability extends beyond simple script execution, as it creates opportunities for session hijacking and credential theft within trusted user sessions. Attackers can leverage this weakness to steal session cookies, capture login credentials, or perform actions on behalf of authenticated users. The vulnerability particularly affects the web UI components of IBM InfoSphere Information Server, which are commonly used for administrative tasks and data management operations, making it a significant concern for organizations relying on the platform for critical data processing activities.
Organizations should implement immediate mitigations including input validation and output encoding controls to prevent malicious scripts from being executed. The recommended approach involves implementing proper sanitization of all user inputs and ensuring that any data rendered in web pages is properly escaped according to the context in which it appears. Additionally, organizations should consider implementing content security policies and regularly updating their systems to address known vulnerabilities. This vulnerability aligns with ATT&CK technique T1531 which focuses on use of web shell, and represents a common vector for privilege escalation and persistent access within enterprise environments.
