Yersinia | a network exploitation tool

Yersinia is a network tool designed to take advantage of some weakeness in different network protocols. It pretends to be a solid framework for analyzing and testing the deployed networks and systems.

Currently, there are some network protocols implemented, but others are coming (tell us which one is your preferred). Attacks for the following network protocols are implemented (but of course you are free for implementing new ones):

1. Spanning Tree Protocol (STP)
2. Cisco Discovery Protocol (CDP)
3. Dynamic Trunking Protocol (DTP)
4. Dynamic Host Configuration Protocol (DHCP)
5. Hot Standby Router Protocol (HSRP)
6. IEEE 802.1Q
7. IEEE 802.1X
8. Inter-Switch Link Protocol (ISL)
9. VLAN Trunking Protocol (VTP)

Attacks

Spanning Tree Protocol

1. Sending RAW Configuration BPDU
2. Sending RAW TCN BPDU
3. DoS sending RAW Configuration BPDU
4. DoS sending RAW TCN BPDU
5. Claiming Root Role
6. Claiming Other Role
7. Claiming Root Role dual home (MITM)

Cisco Discovery Protocol

1. Sending RAW CDP packet
2. DoS flooding CDP neighbors table
3. Setting up a virtual device

Dynamic Host Configuration Protocol

1. Sending RAW DHCP packet
