[原文]Buffer overflow in the web interface for SOHO Routefinder 550 before firmware 4.63 allows remote attackers to cause a denial of service (reboot) and execute arbitrary code via a long GET /OPTIONS value.
A vulnerability has been discovered in Multitech RouteFinder 550 VPN firmware release 4.63 and earlier. The problem occurs due to insufficient bounds checking of data supplied in HTTP GET requests. By passing excessive data to the device it may be possible for a remote attacker to corrupt memory.
Successful exploitation of this bug may result in a denial of service, causing the device to crash. Although it has not been confirmed, it may also be possible for an attacker to exploit this issue to execute arbitrary commands.
