Hi, There are 2 sql injections in Tikiwiki 1.9.4 (and maybe before versions) : I) There is a call to "get_process()" function in "tiki-g-admin_processes.php" file, without checking "pid" parameter : File /tiki-g-admin_processes.php, Line 35 : :: $info = $processManager->get_process($_REQUEST["pid"]); Lets take a look at the "get_process()" function : File /lib/Galaxia/src/ProcessManager/ProcessManager.php, Line 419 : :: function get_process($pId) :: { >> $query = "select * from ".GALAXIA_TABLE_PREFIX."processes where pId=$pId"; :: $result = $this->query($query); :: if(!$result->numRows()) return false; :: $res = $result->fetchRow(); :: return $res; :: } II) The "where" parameter in "tiki-g-admin_processes.php" file, is not checked properly : File /tiki-g-admin_processes.php, Line 155 : :: if (isset($_REQUEST['where'])) { >> $where = $_REQUEST['where']; :: } File /tiki-g-admin_processes.php, Line 183 : :: $items = $processManager->list_processes($offset, $maxRecords, $sort_mode, $find, $where); File /lib/Galaxia/src/ProcessManager/ProcessManager.php, Line 442 : :: if($where) { :: if($mid) { :: $mid.= " and ($where) "; :: } else { >> $mid.= " where ($where) "; :: } :: } >> $query = "select * from ".GALAXIA_TABLE_PREFIX."processes $mid order by $sort_mode"; :: $query_cant = "select count(*) from ".GALAXIA_TABLE_PREFIX."processes $mid"; :: $result = $this->query($query,$bindvars,$maxRecords,$offset); The original advisory (in Persian) is located at : http://www.hackers.ir/advisories/tikiwiki.html - Omid
