During account assignment in the Talk2M platform, a Cosy+ device generates and sends a certificate signing request (CSR) to the back end. This CSR is then signed by the manufacturer and used for OpenVPN authentication by the device afterward. Since the common name (CN) of the certificate is specified by the device and used in order to assign the OpenVPN session to the corresponding Talk2M account, an attacker with root access to a Cosy+ device is able to manipulate the CSR and get correctly signed certificates for foreign devices.
25253b1bbb687aad196d1a68e6e0528bb19297042bab3325165b8dc98905aec7The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. The Ewon Cosy+ executes all tasks and services in the context of the user "root" and therefore with the highest system privileges. By compromising a single service, attackers automatically gain full system access.

1888a210090f03bc507fc3160727ce580f1a9c9a09e8cbac293d257662b66100The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. Due to improper neutralization of parameters read from a user-controlled configuration file, an authenticated attacker is able to inject and execute OS commands on the device.
8a1d1fc9f6b69674b1ce58ab3538a8faa0b20d3e41c26e9d4d475e8d597b5ed5The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. The credentials used for the basic authentication against the web interface of Cosy+ are stored in the cookie "credentials" after a successful login. An attacker with access to a victim's browser is able to retrieve the administrative password of Cosy+.
e33c07108e3c442346ea02e832a872e3a605c556106af6c539e021e9820cf456The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. If login against the FTP service of the Cosy+ fails, the submitted username is saved in a log. This log is included in the Cosy+ web interface without neutralizing the content. As a result, an unauthenticated attacker is able to inject HTML/JavaScript code via the username of an FTP login attempt.
2db40156b7623d221c6a2ba726715a466f4672d315691354c619b685d3367967The AudioCodes VoIP phones can be managed centrally, whereby configuration files are provided and requested by the phones at a central location. These configuration files can also be provided in encrypted form. This is intended to protect sensitive information within the configuration files from unauthorized access. Due to the use of a hardcoded cryptographic key, an attacker is able to decrypt encrypted configuration files and retrieve sensitive information. Firmware versions greater than or equal to 3.4.8.M4 are affected.
aa8123253e08b34d540bf926ba4a87654940b99a7e069721ef96a63db69bac95The AudioCodes VoIP phones store sensitive information, e.g. credentials and passwords, in encrypted form in their configuration files. These encrypted values can also be automatically configured, e.g. via the "One Voice Operation Center" or other central device management solutions. Due to the use of a hardcoded cryptographic key, an attacker with access to these configuration files is able to decrypt the encrypted values and retrieve sensitive information, e.g. the device root password. Firmware versions greater than or equal to 3.4.8.M4 are affected.
