Executive Summary

This vulnerability involves the use of a hard-coded cryptographic key in Johnson Controls ADVMS software versions before 3.10. This allows attackers to read sensitive constants within the executable, potentially exposing encrypted data or system secrets.

Impact Analysis

An attacker could exploit this to gain unauthorized access to sensitive information, decrypt communications, or perform further attacks on the system. This may lead to data breaches, system compromise, or unauthorized control of connected building management systems.

Compliance Impact

This vulnerability could violate compliance requirements for data protection and encryption standards in GDPR and HIPAA. Failure to address it may result in legal penalties, loss of certification, and increased risk of data exposure.

Mitigation Strategies

Update ADVMS to version 3.10 or later to address the hard-coded cryptographic key vulnerability. If immediate update is not possible, isolate affected systems and restrict access to minimize exposure.
