Title: Net-SNMP Trap And Request Handling Vulnerabilities
Severity: CRITICAL
Description:
Net-SNMP is a freely available, open source implementation of the SNMP protocol. It was previously known as UCD-SNMP.
A problem with Net-SNMP may allow remote attackers to exploit the protocol implementation. The problem is in the handling of traps and requests.
SNMP requests are messages sent from manager to agent systems. They typically poll the agent for current performance or configuration information, ask for the next SNMP object in a Management Information Base (MIB), or modify the configuration settings of the agent. SNMP traps are messages sent from agent to manager systems. They typically notify the manager that some event has occured or otherwise provide information about the status of the agent.
Multiple vulnerabilities have been discovered in a number of SNMP implementations. This vulnerability entry is for the Net-SNMP implementation, identifying the "Multiple Vendor SNMP Trap Handling Vulnerabilities" described in BID 4088, and "Multiple Vendor SNMP Request Handling Vulnerabilities" discussed in BID 4089.
Among the possible consequences are denial of service and allowing attackers to compromise target systems.
