## Technical details

A vulnerability classified as HTML Injection (related to CWE-79) exists in several HCL Software products, including Unica and Campaign, due to improper neutralization of user-supplied input before it is rendered on a web page. An unauthenticated remote attacker can exploit this by convincing a user to visit a specially crafted link or page, leading to the execution of arbitrary HTML in the victim's browser context. This can be leveraged to perform data exfiltration by forcing the browser to interact with attacker-controlled external resources. The vulnerability is present in versions up to and including 25.1.1, and patches are available via HCL customer support.
