sqlmap is an open source command-line automatic SQL injection tool. Its goal is to detect and take advantage of SQL injection vulnerabilities in web applications. Once it detects one or more SQL injections on the target host, the user can choose among a variety of options to perform an extensive back-end database management system fingerprint, retrieve DBMS session user and database, enumerate users, password hashes, privileges, databases, dump entire or user's specified DBMS tables/columns, run his own SQL statement, read or write either text or binary files on the file system, execute arbitrary commands on the operating system, establish an out-of-band stateful connection between the attacker box and the database server via Metasploit payload stager, database stored procedure buffer overflow exploitation or SMB relay attack and more.

This Metasploit module takes advantages of Archive_Tar versions prior to 1.4.11 which fail to validate file stream wrappers contained within filenames to write an arbitrary file containing user controlled content to an arbitrary file on disk. Note that the file will be written to disk with the permissions of the user that PHP is running as, so it may not be possible to overwrite some files if the PHP user is not appropriately privileged.
