AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a stored cross-site scripting (XSS) issue in the Trusted Certificates feature of pdfonline.foxit.com. An attacker can inject a malicious script by crafting a payload as the certificate name. This script is then stored and executed every time the Trusted Certificates view is loaded because the input is not properly sanitized before being rendered in the DOM.
How can this vulnerability impact me? :
The vulnerability can lead to the execution of malicious scripts in the context of the user's browser when viewing the Trusted Certificates. This can result in unauthorized actions such as stealing sensitive information, session hijacking, or performing actions on behalf of the user without their consent.
