CyberRota Analysis
AI-GeneratedArista EOS systems configured with DHCP relay are vulnerable to unauthenticated attacks, allowing an attacker to send malicious DHCP reply packets from unauthorized IP addresses. This can lead to the provision of harmful network configurations to clients, potentially enabling traffic interception or denial of service. Organizations using Arista EOS with DHCP relay should prioritize patching to mitigate this critical vulnerability.
Original NVD Description
On affected platforms running Arista EOS with Dynamic Host Configuration Protocol (DHCP) relay configured, an unauthenticated attacker with network access could send a crafted DHCP reply packet from an IP address that is not configured as a helper address, and the relay agent would forward it to clients without validating the source. This could allow the attacker to supply clients with malicious network configuration parameters, potentially resulting in traffic interception or denial of service for affected clients.
