Session information disclosure via missing security headers
Published Apr 12, 2022 · Updated Aug 3, 2024
Improper access control in Siemens SCALANCE X-300 firmware before 4.1.4 allows remote attackers to obtain confidential session data. The integrated web server omits unspecified security headers that would otherwise protect session information from extraction. Exploitation requires adjacent-network access, high complexity, and user interaction; published details do not identify the headers or exact interaction.
