Joomla 2.5中的会话固定问题

Question

这可能会导致的影响：可能会窃取或操纵客户会话和Cookie，这可能用于冒充合法用户，允许黑客查看或更改用户记录，以及以该用户的身份执行交易。

建议的防止会话修复攻击的解决方案是在用户登录时更新会话ID。此修复可以在代码级别或框架级别完成，具体取决于会话管理功能的实现位置。

我试图找到一个解决方案，但仍然不成功。任何人都可以帮助如何解决这个在Joomla 2.5？

我想在框架级别实现此修复。任何帮助将不胜感激。

非常感谢@ryadavalli！这非常有帮助。使用你建议的解决方案，我解决了它的Joomla 2.5。

只有很少的变化;为Joomla 2.5需要的代码被放置在

1. 库/的Joomla /应用/ application.php
2. 库/的Joomla /会话/ session.php文件

在application.php WRT您的解决方案

public function login($credentials, $options = array()) 
    { 
     // Get the global JAuthentication object. 
     jimport('joomla.user.authentication'); 

     $authenticate = JAuthentication::getInstance(); 
     $response = $authenticate->authenticate($credentials, $options); 

     // Import the user plugin group. 
     JPluginHelper::importPlugin('user'); 

     if ($response->status === JAuthentication::STATUS_SUCCESS) 
     { 
      $session = &JFactory::getSession(); 
        // we fork the session to prevent session fixation issues 
      $session->fork(); 
      // validate that the user should be able to login (different to being authenticated) 
      // this permits authentication plugins blocking the user 
      $authorisations = $authenticate->authorise($response, $options); 

在session.php文件，更新的代码如下

public function fork() 
    { 
     if ($this->_state !== 'active') 
     { 
      // @TODO :: generated error here 
      return false; 
     } 

     // Save values 
     $values = $_SESSION; 

     // Keep session config 
     /*$trans = ini_get('session.use_trans_sid'); 
     if ($trans) 
     { 
      ini_set('session.use_trans_sid', 0); 
     } */ 
     $cookie = session_get_cookie_params(); 

     // Create new session id 
     //$id = $this->_createId(); 

      session_regenerate_id(true); 
      $id = session_id(); 

      // first we grab the session data 
      $data = $this->_store->read(); 

     // Kill session 
     session_destroy(); 

     // Re-register the session store after a session has been destroyed, to avoid PHP bug 
     $this->_store->register(); 

     // Restore config 
     ini_set('session.use_trans_sid', $trans); 
     session_set_cookie_params($cookie['lifetime'], $cookie['path'], $cookie['domain'], $cookie['secure']); 

     // Restart session with new id 
     session_id($id); 
     session_start(); 

     $_SESSION = $values; 

      //now we put the session data back 
      $this->_store->write($id, $data); 

     return true; 
    }

我为Joomla 3.x版本做了这个。它应该与2.5相似。 你应该修改2个文件来完成这项工作。

1. 库/ CMS /应用/ cms.php

2. 库/的Joomla /会话/ session.php文件

在cms.php修改函数登录

// Import the user plugin group. 
      JPluginHelper::importPlugin('user'); 

      if ($response->status === JAuthentication::STATUS_SUCCESS) 
      { 
        $session = &JFactory::getSession(); 
        // we fork the session to prevent session fixation issues 
        $session->fork(); 

        /* 
        * Validate that the user should be able to login (different to being authenticated). 
        * This permits authentication plugins blocking the user. 
        */ 
        $authorisations = $authenticate->authorise($response, $options); 

in session.php更改函数fork（）以包含

function fork() 
    { 
      if($this->_state !== 'active') { 
        // @TODO :: generated error here 
        return false; 
      } 

      // save values 
      $values = $_SESSION; 

      // keep session config 
      /*$trans  =  ini_get('session.use_trans_sid'); 
      if($trans) { 
        ini_set('session.use_trans_sid', 0); 
      } */ 
      $cookie =  session_get_cookie_params(); 
      // create new session id 
      //$id =  $this->_createId(strlen($this->getId())); 
      session_regenerate_id(true); 
      $id = session_id(); 

      // first we grab the session data 
      $data = $this->_store->read($this->getId()); 

      // kill session 
      session_destroy(); 

      // re-register the session store after a session has been destroyed, to avoid PHP bug 
      $this->_store->register(); 

      // restore config 
      ini_set('session.use_trans_sid', $trans); 
      session_set_cookie_params($cookie['lifetime'], $cookie['path'], $cookie['domain'], $cookie['secure'], true); 

      // restart session with new id 
      session_id($id); 
      //session_regenerate_id(true); 
      session_start(); 
      $_SESSION = $values; 

      //now we put the session data back 
      $this->_store->write($id, $data); 
      return true; 
    }
