## Technical details

An open redirect vulnerability (CWE-601) exists in the Microchip GridTime 3000 GNSS Time Server within the password change form submission component. The application fails to properly validate or sanitize the destination URL after a password change action, allowing a remote attacker with low privileges to redirect users to arbitrary external domains. This is typically exploited by crafting a malicious link that appears to be a legitimate administrative action but sends the victim to an attacker-controlled site upon completion. The vulnerability affects versions 1.0r0.03 through 1.1r0.0.
