CVE-2025-62320 | HTML Injection Leading to Data Exfiltration to External Server vulnerability affects HCL Unica Platform

HTML Injection can be carried out in Product when a web application does not properly check or clean user input before showing it on a webpage. Because of this, an attacker may insert unwanted HTML code into the page. When the browser loads the page, it may automatically interact with external resources included in that HTML, which can cause unexpected requests from the user’s browser.

4.7 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
