  1. Cisco Router Hacking Group 8 Vernon Guishard Kelvin Aguebor ECE 4112

  2. Introduction • Cisco Systems, Inc. sells networking and communications technology and services. • Cisco is known for creating the first commercially successful multi-protocol router. • March 2000, Cisco had the market capitalization of $500 billion. • Currently, it has a market cap of $175 billion, controls 58% of the market sale of routers. • The Cisco routers have been more likely to have attacks. • Large market share can lead to attacks being devastating for the internet.

  3. Identifying Routers and Vulnerabilities • Nmap is used to identify the router. • OS fingerprinting • Telnet is another solution to track down routers. • Trademark Cisco Banner “User Access Verification” • SING is used to identify the router. • It uses ICMP packets to find the router • Nessus can be used to find vulnerabilities.

  4. Cisco Vulnerabilities • Console Password Recovery • All Cisco routers and switches affected • Not regarded as a vulnerability • A way for System Admin to recover lost passwords • May be used by hackers who have physical access to machines • HTTP Configuration Arbitrary Administrative Access Vulnerability • Cisco IOS release 11.3 or higher, are vulnerable. • Attacker can gain access to a router without authentication • Attacker can completely control, change, and configure the device • http://10.0.1.252/level/99/exec/show/config

  5. Cisco Vulnerabilities • Router Denial of Service (DOS) Vulnerability • It affects all Cisco routers and switches from releases 11.1 through 12.1 • Causes the routers and switches to stop forwarding packets on specific interface • IPv4 packets with protocol type of 53, 55, 77 or 103 causes input queue to be flagged as full • Telnet Buffer Overflow Vulnerability • Cisco Broadband Operating System (CBOS), an operating system for the Cisco 600 family of routers are vulnerable • Extremely long telnet passwords cause the router to crash then reboot • Attacker can repeat until fixed, causing a DOS

  6. Solutions to Vulnerabilities • Vulnerabilities know by Cisco and Patches Released • Most lingering vulnerabilities due to poor network administration • Upgrade Cisco IOS • Use access-list if not able to upgrade • TACAS or Radius effective in preventing HTTP vulnerability

  7. Lab Procedures • Section 1: Console Password Exploit • Using hyper terminal to access routers • Obtaining enable password and enable secret of the router • Section 2: Identifying Cisco Routers • Using NMAP and telnet to identify routers • Section 3: Network Exploits • Using the Cisco Global Exploit tool • Protecting against the Cisco Global Exploit tool
