Detailsinfo

A vulnerability was found in Rockwell Automation Allen-Bradley Logix5000 up to 21.00 (Automation Software). It has been classified as critical. Affected is some unknown processing of the component CIP Packet Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
