Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the Microchip GridTime 3000 GNSS Time Server due to improper neutralization of user-supplied input during web page generation (CWE-79). The vulnerability is reachable over the network and requires low-privileged authentication and some level of user interaction (such as a victim clicking a malicious link). An attacker can exploit this to execute arbitrary JavaScript in the context of the victim's session, which may be leveraged alongside other web vulnerabilities like CSRF to modify device settings or impact availability. The issue affects firmware versions 1.0r0.03 through 1.1r0.0.
