## Technical details

A classic buffer overflow (CWE-120) exists in the device registration function of InHand Networks IR912 and IR915 routers. The vulnerability is caused by a buffer copy without checking the size of the input during the registration process. A remote, unauthenticated attacker can exploit this over the network by sending a specially crafted request. Successful exploitation results in a denial of service (DoS) condition, crashing the target device. The issue affects firmware versions up to and including V1.0.0.r20042.

## Affected products

- InHand Networks IR912 V1.0.0.r20042 and earlier
- InHand Networks IR915 V1.0.0.r20042 and earlier
