GRE and GRE6 Protocols Traffic Spoofing Vulnerability
Vulnerability
A vulnerability exists in the Generic Routing Encapsulation (GRE) and GRE6 protocols, as defined in RFC 2784, due to a lack of validation for the source of network packets. This flaw allows an attacker to spoof and route arbitrary traffic through an exposed network interface. The vulnerability can lead to spoofing, bypassing access controls, and causing unexpected network behaviors.
Impact
Exploitation of this vulnerability can result in spoofing attacks, bypassing of access controls, and other unanticipated network issues.
