Summary

A vulnerability in the cluster management interface of Cisco SD-WAN vManage Software could allow an unauthenticated, remote attacker to view sensitive information on an affected system. To be affected by this vulnerability, the Cisco SD-WAN vManage Software must be in cluster mode. This vulnerability is due to the absence of authentication for sensitive information in the cluster management interface. An attacker could exploit this vulnerability by sending a crafted request to the cluster management interface of an affected system. A successful exploit could allow the attacker to allow the attacker to view sensitive information on the affected system.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
