Hard-Coded Cryptographic Key in Wertheim SafeController Software

Publication date: 2026-06-15

Last updated on: 2026-06-15

Assigner: SEC Consult Vulnerability Lab

Description
The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains a hard-coded cryptographic key in the SafeSystem.Infrastructure.Security.dll component. An attacker with access to the application files can reverse engineer the DLL and recover the hard-coded cryptographic key. This key can be used to decrypt the licence.whs file, which contains sensitive information about the licensing party and a second key that can be used to decrypt other configuration files.

Executive Summary

The vulnerability exists in the Wertheim SafeController Software, specifically in the SafeSystem.Infrastructure.Security.dll component. It contains a hard-coded cryptographic key. An attacker who has access to the application files can reverse engineer this DLL to extract the hard-coded key.

This key can then be used to decrypt the licence.whs file, which holds sensitive information about the licensing party and another key. This second key can be used to decrypt other configuration files, potentially exposing more sensitive data.

Compliance Impact

The vulnerability involves a hard-coded cryptographic key that can be extracted by an attacker to decrypt sensitive licensing information and configuration files. This exposure of sensitive data could potentially lead to non-compliance with data protection standards such as GDPR or HIPAA, which require adequate protection of sensitive information through strong cryptographic controls.

However, the provided context does not explicitly mention the impact on compliance with specific standards or regulations.

Mitigation Strategies

The vulnerability involves a hard-coded cryptographic key in the SafeSystem.Infrastructure.Security.dll component of Wertheim SafeController Software. To mitigate this vulnerability, immediate steps include restricting access to the application files to prevent attackers from reverse engineering the DLL and recovering the key.

Additionally, it is recommended to perform a thorough security review of the product to identify and resolve potential vulnerabilities.

Although no specific patch details are provided for this CVE, similar vulnerabilities in Wertheim SafeController software have vendor patches available, so checking for and applying any vendor updates or patches is advised.

Impact Analysis

If exploited, this vulnerability allows an attacker to access sensitive licensing information and potentially other confidential configuration data by decrypting protected files using the recovered cryptographic keys.

This could lead to unauthorized disclosure of sensitive information, compromise of software licensing integrity, and possibly further exploitation depending on the nature of the decrypted configuration files.
