Risk Summary

ATTENTION: Remotely exploitable/low skill level to exploit.

CVEs (1)

Remediations

  • Rockwell Automation has provided interim compensating controls for Allen-Bradley Stratix and ArmorStratix switches to help reduce the risk of exploitation of the vulnerability identified in the Cisco Cluster Management Protocol (CMP) processing code used in the Cisco IOS and Cisco IOS XE software. Allen-Bradley Stratix and ArmorStratix products contain the affected versions of the Cisco IOS and IOS XE software.
  • Disable the Telnet protocol as an allowed protocol for incoming connections on affected devices to diminish the network-based vector of attack. For information on how to disable Telnet via Command Line Interface, please see Knowledgebase Article ID 1040270, which is available at the following location (with a valid account):
  • If a user is unable or unwilling to disable Telnet, then implementing infrastructure access control lists (iACLs) can reduce the attack service. For information on how to implement iACLs, please see Knowledgebase Article ID 1040270.
  • Cisco has created two Snort rules (SIDs), 41909 and 41910, to detect exploits associated with this vulnerability.
  • Rockwell Automation security advisory, Stratix CMP Remote Code Execution Vulnerability, is available at the following location (with a valid account):
  • Cisco's security advisory, Cisco IOS and IOS XE Software Cluster Management Protocol Remote Code Execution Vulnerability, is available at the following location:
