Summary

ABB identified vulnerabilities in the SQLite library bundled with B&R Automation Studio versions earlier than 6.5. These vulnerabilities include buffer overflow, memory corruption, and integer overflow issues (CWE-197, CWE-122, CWE-119, CWE-787, CWE-190, CWE-125, CWE-120) that could enable unauthorized access, data exposure, or remote code execution. Although no successful exploitation of B&R products was observed during testing, the underlying SQLite vulnerabilities present potential attack vectors when exposed to untrusted network input.

What this means
What could happen
An attacker with network access to B&R Automation Studio could potentially execute arbitrary code or access sensitive data, which could lead to unauthorized modifications of industrial automation programs or theft of proprietary engineering data.
Who's at risk
Engineering teams and automation engineers who use B&R Automation Studio to develop, test, or maintain industrial automation programs on manufacturing equipment, process control systems, and machinery.
How it could be exploited
An attacker on the network sends a specially crafted request to B&R Automation Studio that exploits buffer overflow or memory corruption vulnerabilities in the bundled SQLite library. This could allow the attacker to run commands with the privileges of the Automation Studio process.
Prerequisites
  • Network access to the B&R Automation Studio application port
  • B&R Automation Studio version 6.4 or earlier installed and accessible from the network
