CVE-2021-42258 is an unauthenticated SQL injection vulnerability in BQE BillQuick Web Suite 2018 through 2021 releases before 22.0.9.1. Attacker-controlled input to the application’s username field can be interpreted as SQL syntax. In affected Microsoft SQL Server deployments, injection may be leveraged to invoke xp_cmdshell and execute arbitrary operating-system commands under the SQL Server service account.

This repository contains a single Metasploit auxiliary module targeting a SQL injection vulnerability (CVE-2021-42258) in BillQuick Web Suite versions prior to 22.0.9.1. The exploit leverages error-based SQL injection via the 'txtID' POST parameter on the '/ws2020/default.aspx' endpoint. The module is capable of extracting the database name, version banner, current user, hostname, and dumping the contents of the SecurityTable (user table), which may include usernames and password hashes or encrypted values. The exploit requires the target to be running the vulnerable BillQuick Web Suite with an MSSQL backend and accessible over HTTP. The code is written in Ruby and is structured as a standard Metasploit module, making use of Metasploit's SQLi and HTTP client libraries. No hardcoded IPs or domains are present; the endpoint is specified by the user via module options.
