Cross Site Scripting In Psychostats

Description:
PsychoStats is a statistics generator for games. Currently there is support
for a handful of Half-Life "MODs" including Counter-Strike, Day of Defeat,
and Natural Selection. PsychoStats gathers statistics from the log files that
game servers create by reading through the logs and then calculating detailed
statistics for players, maps, weapons and clans. These detailed statistics
are stored in a MySQL database which are then viewed online from your website
using a set of PHP web pages. There are some complaints out there in the
community that do not like the fact that PsychoStats does not provide 'real time'
game statistics. The fact is, providing 'real time', accurate and detailed
statistics is a hard issue to overcome. Some game statistic generators out there
that provide 'real time' statistics simply do not have the same amount of detailed
information that PsychoStats has. And they usually only provide very basic 'kill'
statistics. Ignoring detailed 'map' and 'clan' statistics. PsychoStats may not be
real time, but it works very close to it. As data is stored in a mysql database old
logs that were scanned previously do not need to be scanned again, which makes for
much faster updates then the old v1.x of PsychoStats. And the data provided by
PsychoStats is very detailed.
Cross Site Scripting:
Cross site scripting exists in Jason Morriss PsychoStats. This vulnerability
exists due to user supplied input not being checked properly. Below is an example.
http://www.example.com/stats/login.php?login=%22%3E%3Ciframe%3E
This vulnerability could be used to steal cookie based authentication
credentials within the scope of the current domain, or render hostile code
in a victim's browser.
Solution:
The vendor was contacted, responded very promptly and said he will be addressing the
issue soon and has released an updated version of the software.
