CVE-2026-2485 represents a critical stored cross-site scripting vulnerability affecting IBM Infosphere Information Server versions 11.7.0.0 through 11.7.1.6. This vulnerability resides in the web user interface component of the information server platform, where malicious input is not properly sanitized before being rendered back to users. The flaw allows a privileged attacker with sufficient access rights to inject malicious JavaScript code into the application's data storage, which then executes whenever other users view the affected content. This type of vulnerability falls under CWE-79, which specifically addresses cross-site scripting flaws where untrusted data is incorporated into web pages without proper validation or encoding.
The security implications of this vulnerability are severe as it enables attackers to manipulate the intended functionality of the application. When a privileged user with administrative or elevated permissions injects malicious code, they can potentially steal session cookies, credentials, or other sensitive information from authenticated users who interact with the compromised content. The attack vector leverages the trust relationship between the user and the application, making it particularly dangerous because victims are likely to trust the legitimate application interface. This vulnerability aligns with ATT&CK technique T1531, which involves modifying or injecting code into applications, and T1071.004, which covers application layer protocol manipulation.
The impact extends beyond simple credential theft, as the injected JavaScript code can perform various malicious activities including redirecting users to phishing sites, modifying application data, or even establishing persistent backdoors within the trusted session environment. IBM Infosphere Information Server is commonly used for data integration and management, making this vulnerability particularly concerning for organizations handling sensitive business data. The vulnerability affects the web-based administrative interface, meaning that any user with sufficient privileges to input data into the system could potentially exploit this weakness. Organizations should prioritize patching this vulnerability as it represents a significant risk to application security and data integrity within their information management infrastructure.
