Last modified
CVE-2016-9343 is a critical-severity vulnerability rated 10/10 on the CVSS scale. An issue was discovered in Rockwell Automation Logix5000 Programmable Automation Controller FRN 16.00 through 21.00 (excluding all firmware versions prior to FRN 16.00, which are not affected). By sending malformed common industrial protocol (CIP) packet, an attacker may be able to overflow a stack-based buffer and execute code on the controller or initiate a nonrecoverable fault resulting in a denial of service.. EPSS estimates a 10.49% chance of exploitation in the next 30 days.
