LG LR Series WAN Router Telnet Daemon Buffer Overflow Vulnerability
The LR series WAN routers are hardware and firmware solutions manufactured and distributed by LG Electronics. It has been discovered that when a stream of data is sent to the telnet daemon when the prompt for a password is presented, the router becomes unstable. By sending a stream of data in the password field of the authentication challenge by the telnet daemon, the router reacts unpredictably. This type of attack typically results in a crash of the router. It has been theorized that this issue is an exploitable buffer overflow. |
