Description:
Multiple vulnerabilities were reported in Cisco IOS and IOS XE. A remote authenticated user can execute arbitrary code on the target system.
A remote authenticated user can send a specially crafted Simple Network Management Protocol (SNMP) packet to the target system to trigger a buffer overflow in the SNMP service and execute arbitrary code on the target system.
For SNMPv2c and before, the SNMP read-only community string is required to exploit this flaw. For SNMPv3, user authentication credentials on the target system are required to exploit this flaw.
Systems configured with the following MIBs are affected:
ADSL-LINE-MIB
ALPS-MIB
CISCO-ADSL-DMT-LINE-MIB
CISCO-BSTUN-MIB
CISCO-MAC-AUTH-BYPASS-MIB
CISCO-SLB-EXT-MIB
CISCO-VOICE-DNIS-MIB
CISCO-VOICE-NUMBER-EXPANSION-MIB
TN3270E-RT-MIB
