Description:
Two vulnerabilities have been reported in various Cisco products, which can be exploited by malicious people to spoof authenticated SNMPv3 packets.

The vulnerabilities are caused due to errors in the authentication code of multiple SNMPv3 implementations and can be exploited via specially crafted SNMPv3 packets using HMAC-MD5-96 or HMAC-SHA-96 as authentication protocol.

Successful exploitation allows to disclose certain network information or make configuration changes on a vulnerable device, but requires that the SNMP server is enabled (disabled by default).

This is related to:
SA30574

The vulnerabilities are reported in the following products:
* Cisco IOS
* Cisco IOS-XR
* Cisco Catalyst Operating System (CatOS)
* Cisco NX-OS
* Cisco Application Control Engine (ACE) Module
* Cisco ACE Appliance
* Cisco ACE XML Gateway
* Cisco MDS 9000 Series Multilayer Fabric Switches
