[-] Blind SQL Injection in /starnet/addons/slideshow_full.php :
128. $query = "SELECT id, description, children FROM $allbum_table WHERE title = '" . $album_name . "'"; <==
129. $result = mysql_query($query) or die(mysql_error() . $query);
130. $RecordCount = mysql_num_rows($result);
131. if ($RecordCount == 0)
132. {
133. print $sas_lang['sn_allbum_no_linkpage'];
134. }
135. else
136. {
137. $allbum_id = mysql_result($result, 0, 0);
138. $allbum_descr = mysql_result($result, 0, 1);
139. $sort_order = mysql_result($result, 0, 2); // [third field of the first query]
140. $sort_array = explode(",", $sort_order); [*]
141.
142. $query = "SELECT children FROM $allbum_table WHERE id='" . $allbum_id . "'";
143. $result = mysql_query($query) or die(mysql_error() . $query);
144. $children = mysql_result($result, 0);
145. $children = explode(",", $children);
146.
147. $i = 1;
148. $count = count($sort_array);
149. foreach ($sort_array as $value)
150. {
151. $query = "SELECT path, thumb, description FROM $allbum_table WHERE id = '" . $value . "'"; <==
152. $result = mysql_query($query) or die(mysql_error() . $query);
153. $path = mysql_result($result, 0, 0);
154. $thumb = mysql_result($result, 0, 1);
155. $descr = mysql_result($result, 0, 2);
156. print "\n<a id=\"photo_urls_$i\" href=\"../" . $path . "/" . $thumb . "\"></a>";
157. $title[$i] = $descr;
$album_name parameter isn't properly checked, this results in a sql injection at line 128...an attacker could be
inject other sql code in the third filed of the query to results in another sql injection al line 151, but explode()
function at line 140 will split the injected code by comma (","), so this is only a blind sql injection!
[-] To retrieve the table prefix see error at: http://[host]/[path]/starnet/addons/slideshow_full.php?album_name='
[*] Possible bug fix:
53. if (IsSet ($_GET['album_name']))
54. {
55. $album_name = addslashes($_GET['album_name']);
56. $album_name = htmlspecialchars(strip_tags($album_name)); //remove html tags
57. }
