IBM Infosphere Information Server versions 11.7.0.0 through 11.7.1.6 are vulnerable to a stored cross-site scripting (XSS) vulnerability. This vulnerability allows a privileged user to embed arbitrary JavaScript code in the Web UI, which can alter the intended functionality of the application. Consequently, this may lead to credential disclosure within a trusted session.
The severity of this vulnerability is classified as medium, with a CVSS score of 4.8. Understanding the implications of this vulnerability is crucial for organizations that utilize IBM Infosphere Information Server, as it could expose sensitive information and compromise user accounts.
Currently, there is a known exploit for this vulnerability, indicating the potential for exploitation in the wild. Organizations using affected versions should prioritize patching to mitigate risks associated with this vulnerability.
Organizations should prioritize patching immediately. The risk to organizations includes potential unauthorized access to sensitive data, particularly if the application is exposed to untrusted users.
Vulnerability Details
The official description of this vulnerability indicates that it allows a privileged user to embed arbitrary JavaScript code, thus posing a risk of credential disclosure. The CVSS score of 4.8 indicates a medium severity level, with the vulnerability categorized under CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')).
The vulnerability affects IBM Infosphere Information Server versions 11.7.0.0 through 11.7.1.6, and the vulnerability was published on March 25, 2026.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input in the Web UI. Attackers may leverage this vulnerability through a network attack vector, which requires low complexity and high privileges. User interaction is required to trigger the exploit, making it imperative for organizations to educate their users about the risks.
The attack complexity is low, and once the JavaScript is embedded, it can impact the confidentiality and integrity of user sessions. There is no availability impact associated with this vulnerability.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is significant, as it allows for the alteration of application behavior and potential credential theft. Organizations using IBM Infosphere Information Server must recognize the urgency of addressing this vulnerability to mitigate the risk of exploitation.
The blast radius could extend to all users of the application, especially if proper access controls are not in place. Given the CVSS score of 4.8, organizations should address this vulnerability in their priority patch cycle to prevent potential exploitation.
