A remote unauthenticated attacker can craft a malicious URL containing JavaScript or HTML code, which is executed in the victim's browser when the URL is visited, allowing the attacker to steal session cookies and perform actions on behalf of the victim within the application.\n\n\n\nThe vulnerability was confirmed to affect versions up to 2026.MS3 but later versions may also be vulnerable.","summary":"CGM CLININET does not neutralize user-supplied input in some URLs, so a crafted link runs attacker JavaScript or HTML in the visitor's browser.
