CVE-2017-7924 is an improper input validation vulnerability in Rockwell Automation MicroLogix 1100 controllers (models 1763-L16BWA, 1763-L16AWA, 1763-L16BBB, and 1763-L16DWD). A remote, unauthenticated attacker can send a specially crafted Programmable Controller Communication Commands (PCCC) packet to the controller, causing it to enter a denial-of-service (DoS) condition. The vulnerability is due to insufficient validation of input data in the PCCC protocol handler.

This repository contains a single Metasploit auxiliary DoS module targeting Allen-Bradley MicroLogix 1100 PLCs (models: 1763-L16BWA, 1763-L16AWA, 1763-L16BBB, 1763-L16DWD) running firmware versions 14.00 up to (but not including) 16.00. The exploit leverages CVE-2017-7924, where a specially crafted PCCC packet sent over Ethernet/IP (ENIP) can cause the PLC to enter a Denial of Service state. The module communicates with the PLC over TCP or UDP port 44818, first establishing a session and connection, then sending the malicious packet. The code includes logic to check if the target is vulnerable by querying the device's model and firmware version. The exploit is operational and can be used to disrupt the target PLC's operation, but does not provide a shell or further access. The repository is structured as a single Ruby file compatible with the Metasploit framework.
