The Red-M 1050AP Lan Access Point is a hardware device which provides a
LAN access point to Bluetooth devices. The device supports a web based
administration interface.
An issue has been discovered which could deny PPP users acces to the device.
Upon making a PPP connection to the Access Point, when prompted for PPP authentication credentials, an unusually long string of data supplied in the username field may initiate a denial of service condition. As a result, any new connection attempts will result in an 'Unable to establish a connection' error message.
A manual restart of the device may be required in order to regain normal functionality.
It is possible that this is the result of a boundary condition error, such as a buffer overflow. In this case, it is possible that exploitation could result in memory corruption, and possibly in the execution of arbitrary code. This has not, however, been confirmed. Normally, there is a small hole where you can use a small pin to poke the reset button.... Otherwise, just fumble around with it, and you probably find something :)
