CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-4574 is a SQL Injection vulnerability found in SourceCodester Simple E-learning System version 1.0, specifically in the User Profile Update component.'}, {'type': 'paragraph', 'content': "The vulnerability occurs because the application does not properly sanitize the input for the POST parameter named 'firstName'. This allows an authenticated attacker to inject malicious SQL commands."}, {'type': 'paragraph', 'content': "Attackers can exploit this flaw using various SQL injection techniques such as time-based blind, boolean-based blind, and error-based SQL injection by sending crafted payloads in the 'firstName' parameter."}, {'type': 'paragraph', 'content': 'The vulnerability enables attackers to execute arbitrary SQL commands on the backend MySQL database, potentially compromising the system.'}] [1]

Impact Analysis

This vulnerability can have serious impacts including unauthorized access to the database.

  • Attackers can dump all database tables, columns, and sensitive data such as user credentials.
  • It may allow attackers to bypass authentication mechanisms by modifying data.
  • Attackers can alter or delete existing database records, compromising data integrity.

Although the attacker must be authenticated to exploit this vulnerability, the ability to execute arbitrary SQL commands poses a significant security risk.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by testing the User Profile Update functionality, specifically the POST parameter named `firstName`, for SQL injection flaws.'}, {'type': 'paragraph', 'content': 'One effective method is to use sqlmap, an automated SQL injection tool, to test the endpoint with crafted payloads.'}, {'type': 'paragraph', 'content': 'An example sqlmap command to detect this vulnerability is:'}, {'type': 'list_item', 'content': 'sqlmap -u "http://127.0.0.1:8081/james_foreman" --data "firstName=John&lastName=Doe&phoneNumber=0&bio=&profile-updateBtn=Update" --batch -v 6 --risk=3 --cookie "PHPSESSID=YOUR_COOKIE_HERE"'}, {'type': 'paragraph', 'content': 'This command sends a POST request with the `firstName` parameter and attempts to identify SQL injection vulnerabilities by injecting various payloads.'}] [1]
