→Monitor for authentication attempts to TCP ports 2601, 2602, and 2604 on ZyXEL ZyWALL devices, which correspond to Quagga/Zebra routing daemon services (Quagga, RIP, and OSPF respectively). ↗

·The hard-coded password for Quagga/Zebra processes is NOT updated even when the appliance's user-facing password is changed by an administrator, meaning standard password rotation does not remediate this vulnerability. ↗
·Vulnerability was confirmed on ZyWALL 1050; other ZyXEL products and firmware versions may also be affected but were unconfirmed at time of disclosure. ↗
