Published Jul 10, 2023 · Updated Jan 27, 2025

Improper access control in Delta Electronics InfraSuite Device Master before 1.0.7 allows remote authenticated users to escalate privileges.

A low-privilege account can gain access to resources reserved for higher-privilege users, although public sources do not identify the exact resulting role.
