Quagga RIPd RIPv1 RESPONSE route injection security bypass
| quagga-ripd-ripv1-response-security-bypass (26251) |  Low Risk |
Description:
Quagga could allow a remote attacker to bypass security restrictions. If RIPv2 authentication is enabled, RIPv1 RESPONSE packets are accepted for updating the routing state. This could allow an unauthenticated remote attacker to inject arbitrary routes into RIPd.
