What is CVE-2022-1669?
CVE-2022-1669 is a medium-severity memory corruption vulnerability in CIRCUTOR COMPACT DC-S BASIC, published on 24 May 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
