CVE-2022-22765
📋 TL;DR
CVE-2022-22765 is a hardcoded credentials vulnerability in BD Viper LT medical laboratory automation systems. Exploitation allows attackers to access, modify, or delete sensitive healthcare data including ePHI, PHI, and PII. Affected organizations include healthcare facilities using BD Viper LT systems for laboratory testing.
💻 Affected Systems
- BD Viper LT System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of medical laboratory systems leading to unauthorized access, modification, or deletion of sensitive patient health information, potential disruption of laboratory operations, and regulatory compliance violations.
Likely Case
Unauthorized access to sensitive healthcare data and potential system configuration changes that could impact laboratory operations.
If Mitigated
Limited impact due to network segmentation, access controls, and monitoring that detect credential misuse attempts.
🎯 Exploit Status
Exploitation requires knowledge of hardcoded credentials and network access to the system. Versions 4.0+ have increased complexity due to OS hardening.
