Description

PunBB contains a flaw that may allow an attacker to carry out an SQL injection attack leading to the forgery of an authentication cookie. The issue is due to the search.php script not properly sanitizing user-supplied input to the 'result_list' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database, which can be used to disclose the registration date of the admin user. Using this date they can then set 'cookie_seed' to their own valid value and pass this cookie in a subsequent request, thus bypassing authentication.
