Sensitive-data disclosure via HTTP Referer leakage
Published Dec 13, 2022 · Updated Apr 22, 2025
Information exposure in Siemens SCALANCE X204RNA devices before 3.2.7 allows remote attackers to read sensitive data leaked in HTTP Referer headers. The HTTP interface leaves sensitive data in a Referer value that a browser sends with a subsequent request; Siemens does not identify the data involved. Exploitation requires user interaction, and the published impact is limited to disclosure of the Referer-carried data.
