CVE-2020-7574Network attack vector

Web-session compromise via stored Server Config script

Published Apr 14, 2020 · Updated Aug 4, 2024

Stored XSS in Siemens Climatix POL908 and POL909 firmware allows remote attackers to compromise other users' web sessions. The Server Config interface stores attacker-supplied JavaScript and later renders it in another user's browser without neutralization. Network access and no system privileges suffice to plant the script, but execution requires another user to open the affected page.
