Path Traversal in Miele Professional (CVE-2017-7240)
Summary
Path traversal in Miele Professional (CVE-2017-7240). Confidential information can be exposed externally. Exploitable via GET /../../../../../../../../../../../../etc/shadow.
Original description
The description as published by the source.
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.

CVE-2017-7240 (Miele Professional) — CWE-22 / CVSS v3 7.5
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: GET /../../../../../../../../../../../../etc/shadow
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
Path traversal (CWE-22) exists in Miele Professional. Attackers reach the vulnerable code path via GET /../../../../../../../../../../../../etc/shadow without authentication.
Check the vendor advisory for the affected versions of Miele Professional. Attack surface: GET /../../../../../../../../../../../../etc/shadow.
Severity: High (CVSS 7.5/10). Confidential information can be exposed externally.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /../../../../../../../../../../../../etc/shadow requests with malformed payloads or SQL meta-characters. Audit SBOM/dependencies to find affected services.
