A vulnerability was identified in many implementations of SNMPv3 which allows an attacker to bypass SNMP authentication. In just a few days a working exploit was released into the wild. With the exploit remote attackers may be able to access and modify any SNMP on an affected system.This could affect many devices, and firmware will need to be updated across the board. The extent of affected systems is not completely known yet, but assume that all devices that implement SNMPv3 are vulnerable.
