A vulnerability was found in Delta Electronics Industrial Automation COMMGR up to 1.08 (Automation Software). It has been classified as critical. This affects an unknown code block. The manipulation as part of a Network Packet 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. The summary by CVE is:

Delta Industrial Automation COMMGR from Delta Electronics versions 1.08 and prior with accompanying PLC Simulators (DVPSimulator EH2, EH3, ES2, SE, SS2 and AHSIM_5x0, AHSIM_5x1) utilize a fixed-length stack buffer where an unverified length value can be read from the network packets via a specific network port, causing the buffer to be overwritten. This may allow remote code execution, cause the application to crash, or result in a denial-of-service condition in the application server.

The bug was discovered 06/21/2018. The weakness was published 06/26/2018 with Zero Day Initiative (Website). The advisory is shared at securityfocus.com.
