DescriptionCVE.org

An authorization bypass vulnerability in Tata Consultancy Services Cognix Recon Client v3.0 allows authenticated users to escalate privileges across role boundaries via crafted requests.

Executive ViewAI

Why It Matters

A high-severity privilege escalation vulnerability in Cognix Recon Client v3.0 allows authenticated users to bypass authorization controls and access resources beyond their assigned role permissions. This affects any organization using this TCS application and poses a significant risk to data confidentiality, integrity, and compliance posture until remediation is implemented.

Business Impact: High

Compensating Controls

Network segmentation to restrict Cognix Recon Client access to authorized personnel only; implement Web Application Firewall (WAF) rules to detect and block suspicious role escalation requests; enforce multi-factor authentication for all users accessing the application; disable non-essential features and API endpoints; increase audit logging and real-time monitoring of authorization events; restrict database-level permissions to limit damage from privilege escalation; implement IP whitelisting for client connections; conduct manual access reviews weekly until patch is available.
