Server account disclosure via path permission error

Published Jun 2, 2020 · Updated Aug 4, 2024

Path-based information disclosure in Sysax Multi Server 6.90 allows remote attackers to learn the web server account name via an invalid path. A crafted /scgi request places an inaccessible folder name in the pid parameter, causing the permission error to expose the service account despite fakepath masking. No authentication or user interaction is required, and the disclosure supports host reconnaissance without modifying data or interrupting the service.
