Vulnerabilities

A heap-based buffer overflow in a network service in Fastweb FASTGate MediaAccess FGA2130FWB, firmware version 18.3.n.0482_FW_230_FGA2130, and DGA4131FWB, firmware version up to 18.3.n.0462_FW_261_DGA4131, allows a remote attacker to reboot the device through a crafted HTTP request, causing DoS.

Fastweb FASTGate GPON FGA2130FWB devices through 2020-05-26 allow CSRF via the router administration web panel, leading to an attacker's ability to perform administrative actions such as modifying the configuration.

An issue was discovered on Fastweb Askey RTV1907VW 0.00.81_FW_200_Askey 2018-10-02 18:08:18 devices. By using the usb_remove service through an HTTP request, it is possible to inject and execute a command between two & characters in the mount parameter.

Fastweb FASTGate 1.0.1b devices allow partial authentication bypass by changing a certain check_pwd return value from 0 to 1. An attack does not achieve administrative control of a device; however, the attacker can view all of the web pages of the administration console.

The web interface on FASTGate Fastweb devices with firmware through 0.00.47_FW_200_Askey 2017-05-17 (software through 1.0.1b) exposed a CGI binary that is vulnerable to a command injection vulnerability that can be exploited to achieve remote code execution with root privileges. No authentication is required in order to trigger the vulnerability.

Fastweb FASTgate 0.00.47 devices are vulnerable to CSRF, with impacts including Wi-Fi password changing, Guest Wi-Fi activating, etc.
