Vulnerability from variot - Updated: 2022-05-17 02:07

The Conexant Access Runner DSL is a broadband router. There is a problem with the authentication mechanism of the Conexant Access Runner DSL Router Console, which can be exploited by remote attackers to access device changes. When connecting to the router console port, an attacker entering any key will return a \"please try again\" message, and then simply enter the Enter key to access the system maintenance menu with administrator privileges. However, this vulnerability is reproduced on some devices, and this issue does not exist on some devices. The authentication mechanism used by the Conexant AccessRunner DSL Console can be bypassed. This could allow a remote user to access the device's configuration settings. There is currently no known reason for why some devices are vulnerable while others are not. This record will be updated if and when further details become available
