Description Andrej Nemec 2017-01-12 15:22:22 UTC 
Security issues were discovered in the passwordauth plugin's use of CGI::FormBuilder, involving API design issues similar to those that led to CVE-2014-1572. Impact:

* An attacker who can log in to a site with a password can log in
  as a different and potentially more privileged user.
* An attacker who can create a new account can set arbitrary fields
  in the user database for that account.

Sites that enable the CGI script (cgi_wrapper) and do not disable the simple password authentication plugin (passwordauth, enabled by default) are affected.
