Technical details

The product generates a daily administrator password using only the device MAC address and date, with no server-side secret. The password generation algorithm can be reverse-engineered from the xwpasswd binary included in the firmware, allowing an attacker to compute valid credentials offline and authenticate without authorization. The vulnerability affects versions 4.3.0 through 5.8.8; the product line reached end-of-life in March 2026.
