Black Shard's team can check your exposure to CVE-2026-124006 and take the fix off your plate.
XWEB EVO through 5.8.8 contains a predictable credential generation vulnerability that allows attackers to derive the Linux root password by computing a fixed prefix combined with a daily password value. Attackers can calculate the deterministic root credential, which before 5.7.0 was identical across all units and from 5.7.0 onward remains derivable from the MAC-based daily password, to gain unauthorized root access to the underlying operating system. This product line reached it's end of service date in March 2026.
