Traffic interception via unencrypted HTTP web interface
Published May 10, 2022 · Updated Dec 9, 2025
Cleartext transmission in Siemens SICAM T before 3.0 allows man-in-the-middle attackers to capture and alter web traffic over HTTP. The device web interface serves client communications over HTTP without transport encryption, exposing requests and responses in transit. Exploitation requires a user to communicate with the device and an attacker able to observe or modify that network path, enabling disclosure or interference with device functions.
