Open redirect and XSS via reset_url parameter
Improper validation of the reset_url parameter of the Setup in-page search in Checkmk <2.5.0p15, <2.4.0p38, <2.3.0p51 and 2.2.0 (EOL) allows an attacker to execute arbitrary script in the session of an authenticated user with Setup access, or to redirect that user to an arbitrary external site, by tricking the user into opening a crafted URL and clicking the Reset button or submitting an empty search.
