CVE-2021-32497 : Vulnerability Insights and Analysis

This article provides detailed information about CVE-2021-32497, a vulnerability found in SICK SOPAS ET before version 4.8.0, allowing attackers to execute arbitrary files through an SDD wrapper.

Understanding CVE-2021-32497

CVE-2021-32497 is a security vulnerability affecting SICK SOPAS ET versions prior to 4.8.0, enabling threat actors to embed malicious executables within an SDD file, executing them when the emulator is initiated.

What is CVE-2021-32497?

The CVE-2021-32497 vulnerability in SICK SOPAS ET permits malevolent actors to package unauthorized executable files in an SDD format, posing a significant risk to users who launch the emulator.

The Impact of CVE-2021-32497

As a critical security flaw, CVE-2021-32497 allows threat actors to introduce unauthorized functionality into the SOPAS ET system, potentially leading to unauthorized code execution and system compromise.

Technical Details of CVE-2021-32497

This section outlines the technical aspects of the CVE-2021-32497 vulnerability including its description, affected systems, and exploitation mechanism.

Vulnerability Description

SICK SOPAS ET versions prior to 4.8.0 are susceptible to an 'Inclusion of Functionality from Untrusted Control Sphere' issue, enabling threat actors to embed arbitrary executables in SDD files for automatic execution without validation.

Affected Systems and Versions

The vulnerability impacts all versions of SICK SOPAS ET before 4.8.0, exposing users to the risk of unauthorized code execution through manipulated SDD files.

Exploitation Mechanism
