#
# [!] Discovered.: DNX
# [!] Vendor.....: http://www.ultrastats.org
# [!] Detected...: 29.06.2008
# [!] Reported...: 04.07.2008
# [!] Response...: xx.xx.2008
#
# [!] Background.: UltraStats is a very flexable log analyzing tool for Call of Duty 2 Server logfiles. 
#                  It is able to parse and consolidate the information it can gather from these logs, 
#                  and put them into a MySQL Database with a very efficient and high optimiced database 
#                  layout.
#
# [!] Bug........: $_GET['id'] in players-detail.php near line 52
#                  
#                  36: if ( isset($_GET['id']) )
#                  37: {
#                  38: 		// get and check
#                  39: 		$content['playerguid'] = DB_RemoveBadChars($_GET['id']);
#
#                  52:     		$sqlquery = "SELECT " .
#                  53:				"sum( " .STATS_ALIASES . ".Count) as Count, " .
#                  54:				STATS_ALIASES . ".Alias as Aliases_Alias, " .
#                  55:				STATS_ALIASES . ".AliasAsHtml as Aliases_AliasAsHtml" .
#                  56:				" FROM " . STATS_ALIASES .
#                  57:				" WHERE PLAYERID = " . $content['playerguid'] . " " .
#                  58:				GetCustomServerWhereQuery(STATS_ALIASES, false) .
#                  59:				" GROUP BY " . STATS_ALIASES . ".Alias " .
#                  60:				" ORDER BY Count DESC";
#
# [!] Tested on..: v0.2.136, v0.2.142
#
# [!] Solution...: no update from vendor till now
#
# [!] Quick fix..: in players-detail.php line 39:
#
#                  - replace:
#                      $content['playerguid'] = DB_RemoveBadChars($_GET['id']);
#
#                  - with:
#                      $content['playerguid'] = intval(DB_RemoveBadChars($_GET['id']));
