Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

XWEB EVO 4.3.0 through 5.8.8 contains a weak password generation vulnerability that allows remote attackers to derive the Administrator code-of-the-day password using only the device MAC address and date, with no server secret involved. Attackers can analyze the firmware binary xwpasswd, which itself functions as the password generator, to compute valid Administrator credentials offline and authenticate to the device without authorization.
