Technical Details


The vulnerability in the Quagga/Zebra routing daemon, exists due to the 
fact that the appliance fails to change the password needed to login 
into the Quagga/Zebra daemon running on ports 2601, 2602 (Quagga/RIP) & 
2604 (Quagga/OSPF) /TCP, even though the password of the appliance has 
been changed an attacker can still use the default password ‘zebra’ to 
log into the Quagga/Zebra service to view and manipulate the routing 
information etc. of the appliance. 

The vulnerability was discovered on ZyWall 1050 appliance other versions 
could be affected as well. 

Information on other vulnerable products and firmwares is pending from 
the vendor’s end.
