Loading vulnerability…
A stack-based buffer overflow exists in the db_netserver component of Lianja SQL Server prior to version 1.0.0RC5.2. The vulnerability can be triggered by sending a specially crafted string to TCP port 8001, potentially allowing remote attackers to crash the daemon or execute arbitrary code.

This repository contains a single Metasploit module (modules/exploits/windows/misc/lianja_db_net.rb) that exploits a stack buffer overflow vulnerability (CVE-2013-3563) in the db_netserver process of Lianja SQL 1.0.0RC5.1. The exploit targets Windows Server 2003 SP1/SP2 and Windows XP SP3 systems where the vulnerable service is accessible on TCP port 8001. The module connects to the service, sends a crafted request to trigger the overflow, and delivers a ROP-based payload (customizable via Metasploit) to achieve remote code execution as a privileged user. The exploit is operational and allows for arbitrary code execution, such as spawning a shell. The code is written in Ruby and is structured as a standard Metasploit exploit module.
