Technical details

IBM Cognos Analytics and Transformer are vulnerable to a stored or reflected cross-site scripting (XSS) attack due to improper neutralization of user-supplied input during web page generation (CWE-79). A remote attacker with low privileges can exploit this by injecting arbitrary JavaScript code into the web user interface. Successful exploitation requires a victim to interact with the malicious content (User Interaction: Required). This can lead to the disclosure of sensitive session information, such as credentials or session tokens, within a trusted session, and allows the attacker to alter the intended functionality of the web interface.
