"Drop Incoming Source-Routed Packets
A source-routed packet attempts to specify the network path the packet should take. If the system is not configured to block the incoming source-routed packets, an attacker can redirect the system's network traffic. Configuring the system to drop incoming source-routed IPv4 packets mitigates this risk."
Parameter:
[yes/no]
Technical Mechanism:
Fix:To configure the system to not accept source-routed packets, add the following line to /etc/sysctl.conf:
net.inet.ip.accept_sourceroute=0
