CVE-2022-29873Network attack vector

Unauthenticated code execution via unvalidated request parameters

Published May 10, 2022 · Updated Dec 9, 2025

Improper parameter neutralization in Siemens SICAM T before 3.0 allows remote attackers to execute code or interrupt the device. The device fails to neutralize delimiters in certain GET and POST parameters before downstream processing; Siemens has not identified the affected parameters. No authentication or user interaction is required, and crafted requests can control the program counter or place the transducer in a denial-of-service state.
