Vulnerability of SNMPc: buffer overflow via TRAP

Synthesis of the vulnerability 

A network attacker can send a TRAP packet in order to execute code on SNMPc.
Vulnerable systems: SNMPc.
Severity of this threat: 3/4.
Creation date: 05/05/2008.
Revision date: 13/11/2008.
Références of this weakness: BID-28990, CVE-2008-2214, NGS00526, VIGILANCE-VUL-7790.

Description of the vulnerability 

The Castle Rock SNMPc Network Manager product centralizes network monitoring. Devices send it SNMP TRAP messages (port 162/udp). These packets contain a Community String to authenticate the sender.

However, if the Community String is too long, a buffer overflow occurs in SNMPc Network Manager. This overflow leads to code execution with LocalSystem privileges.

An unauthenticated network attacker can thus send a SNMP TRAP packet in order to execute code on SNMPc Network Manager.
