## Affected

- ICS-CERT Delta Industrial Automation COMMGR and accompanying PLC Simulators (DVPSimulator EH2, EH3, ES2, SE, SS2 and AHSIM\_5x0, AHSIM\_5x1): version range not reported

## Description

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.
