An attacker with access to the network where the CIRCUTOR Q-SMT is located in its firmware version 1.0.4, could obtain legitimate credentials or steal sessions due to the fact that the device only implements the HTTP protocol. This fact prevents a secure communication channel from being established.

Vulnerability in CIRCUTOR TCP2RS+ firmware version 1.3b, which could allow an attacker to modify any configuration value, even if the device has the user/password authentication option enabled, without authentication by sending packets through the UDP protocol and port 2000, deconfiguring the device and thus disabling its use. This equipment is at the end of its useful life cycle.

An attacker with access to the network where CIRCUTOR Q-SMT is located in its firmware version 1.0.4, could steal the tokens used on the web, since these have no expiration date to access the web application without restrictions. Token theft can originate from different methods such as network captures, locally stored web information, etc.

A buffer overflow vulnerability has been detected in the firewall function of the device management web portal. The device runs a CGI binary (index.cgi) to offer a management web application. Once authenticated with valid credentials in this web portal, a potential attacker could submit any "Address" value and it would be copied to a second variable with a "strcpy" vulnerable function without checking its length. Because of this, it is possible to send a long address value to overflow the process stack, controlling the function return address.
