--------------------------------------------------------------------------------- vtiger CRM <= 5.4.0 (customerportal.php) Two Local File Inclusion Vulnerabilities --------------------------------------------------------------------------------- [-] Software Link: http://www.vtiger.com/ [-] Affected Versions: [1] All versions from 5.1.0 to 5.4.0. [2] All versions from 5.2.0 to 5.4.0. [-] Vulnerability Description: 1) The vulnerable code is located in the get_list_values SOAP method defined in /soap/customerportal.php: 1528. function get_list_values($id,$module,$sessionid,$only_mine='true') 1529. { 1530. require_once('modules/'.$module.'/'.$module.'.php'); 1531. require_once('include/utils/UserInfoUtil.php'); 1532. global $adb,$log,$current_user; 1533. $log->debug("Entering customer portal function get_list_values"); 2) The vulnerable code is located in the get_project_components SOAP method defined in /soap/customerportal.php: 2778. function get_project_components($id,$module,$customerid,$sessionid) { 2779. require_once("modules/$module/$module.php"); 2780. require_once('include/utils/UserInfoUtil.php'); 2781. 2782. global $adb,$log; 2783. $log->debug("Entering customer portal function get_project_components .."); The vulnerabilities exist because these methods fail to properly validate input passed through the "module" parameter, that is being used in a call to the require_once() function (lines 1530 and 2779). This might be exploited to include arbitrary local files containing malicious PHP code. Successful exploitation of these vulnerabilities requires the application running on PHP < 5.3.4, because a null byte injection is required.

[-] Vulnerability Description: 1) The vulnerable code is located in the get_picklists SOAP method defined in /soap/customerportal.php: 1177. $id = $input_array['id']; 1178. $sessionid = $input_array['sessionid']; 1179. $picklist_name = $adb->sql_escape_string($input_array['picklist_name']); 1180. 1181. if(!validateSession($id,$sessionid)) 1182. return null; 1183. 1184. $picklist_array = Array(); 1185. 1186. $admin_role = 'H2'; 1187. $userid = getPortalUserid(); 1188. $roleres = $adb->pquery("SELECT roleid from vtiger_user2role where userid = ?", array($userid)); 1189. $RowCount = $adb->num_rows($roleres); 1190. if($RowCount > 0){ 1191. $admin_role = $adb->query_result($roleres,0,'roleid'); 1192. } 1193. 1194. $res = $adb->pquery("select vtiger_". $picklist_name.".* from vtiger_". $picklist_name." inner join [...] User input passed through the "picklist_name" parameter seems to be correctly sanitised by the sql_escape_string() method, but the vulnerability exists because it's used in the query at line 1194 without single or double quotes.

[-] Vulnerability Description: The vulnerable code is located in the AddEmailAttachment SOAP method defined in /soap/vtigerolservice.php: 458. function AddEmailAttachment($emailid,$filedata,$filename,$filesize,$filetype,$username,$session) 459. { 460. if(!validateSession($username,$session)) 461. return null; 462. global $adb; 463. require_once('modules/Users/Users.php'); 464. require_once('include/utils/utils.php'); 465. $filename = preg_replace('/\s+/', '_', $filename);//replace space with _ in filename 466. $date_var = date('Y-m-d H:i:s'); 467. 468. $seed_user = new Users(); 469. $user_id = $seed_user->retrieve_user_id($username); 470. 471. $crmid = $adb->getUniqueID("vtiger_crmentity"); 472. 473. $upload_file_path = decideFilePath(); 474. 475. $handle = fopen($upload_file_path.$crmid."_".$filename,"wb"); 476. fwrite($handle,base64_decode($filedata),$filesize); 477. fclose($handle); The vulnerability exists because this method fails to properly validate input passed through the "filedata" and "filename" parameters, which are used to write an "email attachment" in the storage directory (lines 475-477). This can be exploited to write (or overwrite) files with any content, resulting in execution of arbitrary PHP code. [-] Solution: The patch provided by the vendor (http://www.vtiger.com/blogs/?p=1467) doesn't fix completely this vulnerability, because a remote authenticated user can still be able to inject and execute arbitrary code.

[-] Original Advisory: http://karmainsecurity.com/KIS-2013-07 ######################################################### ----------------------------------------------------------------------- vtiger CRM <= 5.4.0 (SOAP Services) Authentication Bypass Vulnerability ----------------------------------------------------------------------- [-] Software Link: http://www.vtiger.com/ [-] Affected Versions: All versions from 5.1.0 to 5.4.0. [-] Vulnerability Description: The vulnerable code is located in the validateSession() function, which is defined in multiple SOAP services: function validateSession($username, $sessionid) { global $adb,$current_user; $adb->println("Inside function validateSession($username, $sessionid)"); require_once("modules/Users/Users.php"); $seed_user = new Users(); $id = $seed_user->retrieve_user_id($username); $server_sessionid = getServerSessionId($id); $adb->println("Checking Server session id and customer input session id ==> $server_sessionid == $sessionid"); if($server_sessionid == $sessionid) { $adb->println("Session id match. Authenticated to do the current operation."); return true; } else { $adb->println("Session id does not match. Not authenticated to do the current operation."); return false; } } The vulnerability exists because the "sessionid" parameter isn't properly validated before being compared with the $server_sessionid variable, which is the value returned by the getServerSessionId() function. If called with an invalid session ID, then this function will return "null", in this case the validateSession() will return "true" if the "sessionid" parameter is set to 0, "false", or "null". An attacker can exploit this flaw to bypass the authentication mechanism, e.g. by calling a SOAP method without providing the "username" and "sessionid" parameters.
