+ Details:
+ iWare admin/mods/simplechat_1.0.0/chat_panel.php does not sanatize the $message variable
+ in the first argument of the PostMessage() function on line 11 before writing the variable
+ contents to chat_log.php on line 25. When chat_panel.php is requested, the PostMessage()
+ function is called on line 32 and $_REQUEST['msg'] is written to chat_log.php unsanatized.
+
+ Vulnerable Code:
+ admin/mods/simplechat_1.0.0/chat_panel.php, line(s) 11-32:
+ -> 11: function PostMessage($message) {
+ -> 16: $new_message = "".$message."<br />\n";
+ -> 23: $open_file = fopen("chat_log.php", "w");
+ -> 25: fputs($open_file, stripslashes($new_message));
+ -> 28: fclose($open_file);
+ -> 29: }
+ -> 32: if($_REQUEST['talk']==1){PostMessage($_REQUEST['msg']);}
