Oracle MySQL UDF Payload Execution



This module creates and enables a custom UDF (user defined function) on the target host via the SELECT ... into DUMPFILE method of binary injection. On default Microsoft Windows installations of MySQL (=< 5.5.9), directory write permissions not enforced, and the MySQL service runs as LocalSystem. NOTE: This module will leave a payload executable on the target system when the attack is finished, as well as the UDF DLL, and will define or redefine sys_eval() and sys_exec() functions.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/multi/mysql/mysql_udf_payload
msf exploit(mysql_udf_payload) > show targets
msf exploit(mysql_udf_payload) > set TARGET < target-id >
msf exploit(mysql_udf_payload) > show options
    ...show and set options...
msf exploit(mysql_udf_payload) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
