CVE-2020-7236Network attack vector

Script execution via unneutralized Site Name input

Published Jan 19, 2020 · Updated Aug 4, 2024

Reflected XSS in UHP UHP-100 firmware 3.4.1.15, 3.4.2.4, and 3.4.3 allows remote attackers to execute script via Site Name. The cw2 handler places the td query value from the Site Setup Site Name field into the returned page without neutralizing browser-active content. Exploitation requires victim interaction with a crafted request, and the script runs in the victim's browser context with read and modification access bounded by that session.
