Who is Vulnerable?
Vulnerability Description SNMPc is a secure distributed network management system developed by Castle Rock Computing. SNMPc uses Simple Network Management Protocol (SNMP) to communicate with other network entities. A buffer overflow vulnerability exists in Castle Rock Computing SNMPc Network Manager. The vulnerability can be exploited when an overly long community string is supplied in the SNMP TRAP message. Successful exploitation can lead to the injection and execution of arbitrary code with SYSTEM level privileges. If an attack attempt is either unsuccessful in diverting the process flow or is meant to create a denial of service condition, then the affected service will terminate. In a more sophisticated attack, where code injection is successful, the behaviour of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the System account.
