CVE-2017-7240 — An issue was discovered on Miele Professional PST10 devices

High CVSS 7.5

An issue was discovered on Miele Professional PST10 devices. The corresponding embedded webserver "PST10 WebServer" typically listens to port 80 and is prone to a directory traversal attack; therefore, an unauthenticated attacker may be able to exploit this issue to access sensitive information to aide in subsequent attacks. A Proof of Concept is GET /../../../../../../../../../../../../etc/shadow HTTP/1.1. This affects PG8527 devices 2.02 before 2.12, PG8527 devices 2.51 before 2.61, PG8527 devices 2.52 before 2.62, PG8527 devices 2.54 before 2.64, PG8528 devices 2.02 before 2.12, PG8528 devices 2.51 before 2.61, PG8528 devices 2.52 before 2.62, PG8528 devices 2.54 before 2.64, PG8535 devices 1.00 before 1.10, PG8535 devices 1.04 before 1.14, PG8536 devices 1.10 before 1.20, and PG8536 devices 1.14 before 1.24.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
