Message | SNMP community string buffer overflow attempt with evasion |
Summary | This event is generated when an attempt is made to issue an attack against a machine using SNMP v1. |
Impact | Varies depending on the implementation. Ranges from Denial of Service (DoS) to code execution. |
Detailed Information | SNMP is a widely adopted protocol for managing IP networks, including individual network devices, and devices in aggregate. Several network devices come pre-installed with this protocol for management and monitoring. A number of vulnerabilities exist in SNMP v1, including a community string buffer overflow, that will allow an attacker to execute arbitrary code or shutdown the service. |
Affected Systems | Any implementation of SNMP v1 protocol |
Attack Scenarios | An attacker needs to send a specially crafted packet to UDP port 161 of a vulnerable device, causing a Denial of Service or execution of any command. |
Ease of Attack | Simple. |
Corrective Action | Disable SNMP v1 protocol, use SNMP v2 protocol. Use Ingress/Egress filtering on a packet filtering firewall. |
