An API Endpoint used by Miele's "AppWash" MobileApp in all versions was vulnerable to an authorization bypass. A low privileged, remote attacker would have been able to gain read and partial write access to other users data by modifying a small part of a HTTP request sent to the API. Reading or changing the password of another user was not possible, thus no impact to Availability.

In Miele Benchmark Programming Tool with versions Prior to 1.2.71, executable files manipulated by attackers are unknowingly executed with users privileges. An attacker with low privileges may trick a user with administrative privileges to execute these binaries as admin.

In MIELE XGW 3000 ZigBee Gateway before 2.4.0, a malicious website visited by an authenticated admin user or a malicious mail is allowed to make arbitrary changes in the "admin panel" because there is no CSRF protection.

In MIELE XGW 3000 ZigBee Gateway before 2.4.0, the Password Change Function does not require knowledge of the old password. This can be exploited in conjunction with CVE-2019-20480.

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.
