Not only do configuration files provide information regarding the device, but they also provide additional avenues for further enumeration and possible lateral movement, such as physical and logical neighbor relations, password reuse, user enumeration, and applied access control lists (ACL). Each one of these services provides an avenue to exploit a misconfiguration to download a Cisco configuration file.Ĭisco configuration files can provide a wealth of knowledge for an attacker. Today, I have taken that knowledge and used it to demonstrate how to compromise networks so that I can help clients strengthen their security posture.ĭuring the reconnaissance phase of a penetration test, I typically look for an exposed TFTP, SNMP, and Cisco Smart Install (SMI) service on a network. During that time, I performed best practice assessments aimed at identifying misconfigurations that could lead to a network compromise. ![]() ![]() Prior to making a career change to offensive security, I spent over 15 years working for a Cisco partner designing and implementing enterprise and VoIP networks.
