CVE-2024-30209

Traffic interception via unprotected client resources

Published May 14, 2024 · Updated Aug 2, 2024

Cleartext transmission in Siemens SIMATIC RTLS Locating Manager before 3.0.1.1 allows attackers to read and alter client resources in transit. The server transmits client-side resources without cryptographic confidentiality or integrity protection, exposing their contents and permitting modification on the network path. Exploitation requires a man-in-the-middle position between the server and a client; no authentication or user interaction is required.
