TOCTOU Vulnerability in file exchange

A service running on the affected products contains a potential Time-of-Check Time-of-Use (TOCTOU) race condition. An unauthenticated remote attacker could exploit this race condition to bypass intended security controls. This may result in the execution of unauthorized code.

Sauter: Improper Validation of user-controlled data

A low privileged remote attacker can corrupt the webserver users storage on the device by setting a sequence of unsupported characters which leads to deletion of all previously configured users and the creation of the default Administrator with a known default password.

Sauter: Arbitrary File Upload

A low privileged remote attacker can upload arbitrary data masked as a png file to the affected device using the webserver API because only the file extension is verified.

Sauter: Command Injection

A high privileged remote attacker can influence the parameters passed to the openssl command due to improper neutralization of special elements when adding a password protected self-signed certificate.

Sauter: Directory Traversal in importFile SOAP Method

The importFile SOAP method is vulnerable to a directory traversal attack. An unauthenticated remote attacker bypass the path restriction and upload files to arbitrary locations.

Sauter: Crash via Incomplete SOAP Request

An unauthenticated remote attacker can crash the wscserver by sending incomplete SOAP requests. The wscserver process will not be restarted by a watchdog and a device reboot is necessary to make it work again.

Sauter: Hard-coded Authentication Credentials

The wsc server uses a hard-coded certificate to check the authenticity of SOAP messages. An unauthenticated remote attacker can extract private keys from the Software of the affected devices.

Sauter EY-WS505F0x0 moduWeb Vision before 1.6.0 allows remote attackers to bypass authentication by leveraging knowledge of a password hash without knowledge of the associated password.

Sauter EY-WS505F0x0 moduWeb Vision before 1.6.0 sends cleartext credentials, which allows remote attackers to obtain sensitive information by sniffing the network.
