DescriptionCVE.org

Missing Authentication for Critical Function vulnerability in Microchip TimePictra allows Configuration/Environment Manipulation.This issue affects TimePictra: from 11.0 through 11.3 SP2.

Executive ViewAI

Why It Matters

Timepictra versions through 11.3 contain a critical authentication bypass vulnerability that could allow unauthorized users to access sensitive functions without proper credentials. This affects any organization using vulnerable Timepictra deployments and poses an immediate risk to data confidentiality and system integrity until remediated.

Business Impact: High

Compensating Controls

Implement network-level access controls to limit Timepictra access to trusted internal networks only; deploy WAF rules to monitor and restrict requests to critical functions; enable comprehensive audit logging of all function calls; consider disabling non-essential features if business operations allow; implement API rate limiting and anomaly detection; maintain enhanced monitoring for unauthorized access attempts until patch is applied.
