CWE-121Published: October 5, 2017· Updated: Jun 17, 2026

6.8

CVSS v3.1

Official Description

A Stack-based Buffer Overflow issue was discovered in GE CIMPLICITY Versions 9.0 and prior. A function reads a packet to indicate the next packet length. The next packet length is not verified, allowing a buffer overwrite that could lead to an arbitrary remote code execution.

Technical Analysis

CVE-2017-12732 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 6.8.
