![]() ![]() I am hopeful that the information shared makes both network administrators and security professionals aware of these misconfigures and provides a reference to further improve securing Cisco networks. nmap -sU -p69 -script tftp-enum.nse įigure 20: Port Descriptions 4.0 ConclusionĪs I briefly demonstrated, obtaining a Cisco configuration file could provide an attacker the required information to establish a foothold and laterally move across a network. Since TFTP does not provide a directory listing, the NSE script performs basic enumeration of common Cisco configuration file names. 2.0 Configuration File Download 2.1 TFTPĪfter identifying a TFTP server during the reconnaissance phase, I will rescan the exposed TFTP server port utilizing Nmap with the tftp-enum.nse script. ![]() 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. There are 2 ways to reset the configuration.erase startup-configorwrite erasedon't forget to reload.No Voice.reset config erase write startup cisco. 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. The router can be restarted either by a software. Configuration dHyper-Terminal modifier modifier le wikicode Tout dabord, vous avez besoin dun cble console (cble RJ-45 vers Srie RS232) reliant le. Note: Save the running configuration for the next time that the router is restarted. Now you can do any configuration on the Cisco router. Enter configuration commands, one per line. But to make configuration, you need to enter also teh below command under enable mode: Router configure terminal. 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. Save the running configuration to the startup configuration from the privileged EXEC prompt. After this command you are in enable mode. ![]() Brought to you by the cutting experts at Hypertherm, ProNest can optimize performance for plasma, laser, waterjet, and oxyfuel cutting.
