#VU34200 Cross-site scripting in PRTG Network Monitor - CVE-2020-14073

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via crafted map properties. An attacker with Read/Write privileges can create a map, and then use the Map Designer Properties screen to insert JavaScript code. This can be exploited against any user with View Maps or Edit Maps access. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
