CVE-2020-24913: SQL Injection Vulnerability in qcubed/qcubed

Background

qcubed is an open-source PHP framework that provides a rapid application development environment. It offers a range of features and components to simplify the development process. The vulnerability affects all versions of qcubed, including 3.1.1. The framework includes a profile.php file that is vulnerable to SQL injection attacks when the strQuery parameter is not properly sanitized. This allows an attacker to inject malicious SQL code through a crafted POST request.

Vulnerability Detail

The SQL injection vulnerability in qcubed's profile.php file allows an unauthenticated attacker to access the database by injecting SQL code through a specially crafted POST request. This can lead to unauthorized access, data manipulation, and potentially the compromise of sensitive information stored in the database. The vulnerability has a CVSS score of 9.8, indicating its critical severity.

composer require qcubed/qcubed:3.2

Workaround

If upgrading to the latest version is not immediately feasible, a temporary workaround can be implemented by manually sanitizing and validating the strQuery parameter in the profile.php file. This can be done by using prepared statements or parameterized queries to ensure that user input is properly escaped and treated as data rather than executable code. Here is an example of how to use prepared statements in PHP to mitigate the vulnerability:

// Assuming $strQuery contains the user input

$stmt = $pdo->prepare('SELECT * FROM profiles WHERE query = ?');
$stmt->execute([$strQuery]);
$results = $stmt->fetchAll();

Conclusion

The SQL injection vulnerability in qcubed's profile.php file poses a significant risk to the security and integrity of the application. It is crucial to upgrade to qcubed version 3.2 or later to mitigate the vulnerability. If immediate upgrading is not possible, implementing the provided workaround can help protect against potential attacks.
