Description
Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'SetUserPassword()' function, the 'newPassword' parameter is directly embedded in a shell command string using 'sprintf()' without any sanitisation or validation, and then executed using 'system()'. This allows an attacker to inject arbitrary shell commands that will be executed with the same privileges as the application.

Executive Summary

This vulnerability is a stack-based buffer overflow in Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2. It occurs in the 'SetUserPassword()' function where the 'newPassword' parameter is inserted directly into a shell command string using 'sprintf()' without any sanitization or validation. This unsafe handling allows an attacker to inject arbitrary shell commands that get executed with the same privileges as the application, potentially leading to unauthorized command execution.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary shell commands on the affected device with the same privileges as the application. This could lead to unauthorized control over the device, data compromise, disruption of services, or further exploitation within the network where the device operates.

Mitigation Strategies

The affected Circutor SGE-PLC1000/SGE-PLC50 devices are discontinued since 2015 and have been replaced by newer models. It is recommended to update the firmware to version 2.0.0 or later to mitigate this and related vulnerabilities. [1]
