CVE-2022-40202 : Vulnerability Insights and Analysis

A critical vulnerability, CVE-2022-40202, has been identified in Delta Electronics' InfraSuite Device Master software. The flaw allows attackers to execute remote code due to improper authentication in the database backup function.

Understanding CVE-2022-40202

This section delves into the details of the CVE-2022-40202 vulnerability, its impact, technical aspects, and mitigation strategies.

What is CVE-2022-40202?

The database backup function in Delta Electronics InfraSuite Device Master Versions 00.00.01a and prior lacks proper authentication. Attackers can exploit this by providing malicious serialized objects, enabling unauthorized activation of a backup scheduling function, leading to remote code execution.

The Impact of CVE-2022-40202

With a CVSS base score of 9.8, this critical vulnerability poses a high risk. Attack complexity is low, but the impact on confidentiality, integrity, and availability is severe. The flaw does not require any special privileges or user interaction, making it particularly dangerous.

Technical Details of CVE-2022-40202

Let's explore the technical specifics of CVE-2022-40202 to understand how the vulnerability manifests and its potential reach.

Vulnerability Description

The lack of proper authentication in the database backup function permits the execution of arbitrary code, granting attackers the opportunity to initiate unrestricted processes on the target system, ultimately leading to remote code execution.

Affected Systems and Versions

Delta Electronics' InfraSuite Device Master Versions up to 00.00.01a are affected by this vulnerability. Users of these versions are at risk of exploitation unless immediate action is taken to secure their systems.
