CVE-2017-7924 describes 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 exploit this by sending a specially crafted PCCC packet. This can lead to a Denial of Service (DoS) condition, rendering the controller inoperable. The vulnerability has a CVSS v3 score of 7.5 (High), indicating a network-based attack with low complexity and high availability impact. While not listed on CISA's KEV catalog, a Metasploit module exists for DoS exploitation, though there is minimal community discussion or media coverage.
