The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote user with ability to influence data input can pass a specially crafted Lua script to the database, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
