Security readout for executives and security teams
A very old flaw in Network Associates' Sniffer Distributed Agent lets an attacker on the network send an oversized SNMP community name to crash the agent or run commands on it. If any legacy Sniffer Agent from that era is still deployed, an unauthenticated attacker reachable to the SNMP port could take control of the monitoring host. Very low in modern environments. NAI Sniffer Distributed Agent is legacy software from ~2000; it should not be present on supported networks. Any remaining exposure would be on unmanaged legacy monitoring appliances still listening on SNMP (UDP/161). Low priority unless legacy NAI Sniffer Agents remain in the environment. If any are found, treat as high priority for immediate isolation or removal, since the software is unsupported and the flaw enables remote takeover. Mitigation focus: Inventory hosts for any NAI/Network Associates Sniffer Distributed Agent installs and plan decommissioning.; Block inbound SNMP (UDP/161) to any legacy sniffer agents at network boundaries.; Restrict SNMP access to trusted management VLANs using ACLs and firewall rules..
