T

his vulnerability allows remote attackers to execute arbitrary code on affected installations of Microhard Bullet-LTE prior to v1.2.0-r1112. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of authentication headers. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-10596.
