技术分析

QNAP provide NAS technology solutions to consumers and enterprises. 
 
Multiple vulnerabilities have been identified in the web management  
 
interface. 
 
  
 
1. 命令注入
 
The QNAP Download Station (QDownload) is vulnerable to command injection  
 
as the application executes user-controllable data that is processed by  
 
a shell command interpreter. 
 
  
 
The following resources, accessible post authentication are affected: 
 
www.2cto.com /cgi-bin/Qdownload/DS_RSS_Option.cgi [keyword parameter] 
 
/cgi-bin/Qdownload/DS_RSS_Option.cgi [title parameter] 
 
Commands are executed with the context of the admin user [uid=0(admin)  
 
gid=0(administrators] on the QNAP device.

2. 密码 
 
The QNAP login page stores persistent cookies (including the administrator  
 
username and password) as base64 encoded strings inside the cookie  
 
parameter nas_p. These cookies are not protected with either the HTTPOnly  
 
or Secure flags allowing theft via one of the many cross-site scripting  
 
vulnerabilities which exist within the application (disclosed previously  
 
by another researcher, but never fixed). 
 
  
 
测试证明. 
 
Cookie: qnap_admin_style=default; nas_save_u=1; nas_u=bGFicw==;

nas_tree_x=240; nas_tree_y=370
