SQL Injection in Stumasy Notes Controller

Executive Summary

This vulnerability is a SQL injection flaw in the mjperpinosa stumasy application, specifically in the function Notes_controller::accessing_dictionary_authorization. The issue arises because the user-supplied Password argument is directly concatenated into a SQL query without proper sanitization or parameterization.

An attacker can exploit this by injecting SQL code into the Password field, such as using boolean-based payloads like closing the password string and appending conditions like OR 1=1. This allows bypassing password checks and gaining unauthorized access to the dictionary authorization system.

The vulnerability exists because the prepare() function is used incorrectly, still allowing untrusted input to be concatenated into the SQL query.

Impact Analysis

Exploiting this vulnerability can allow an attacker to bypass authentication controls and gain unauthorized access to the dictionary authorization system.

Depending on the database configuration, the attacker may also be able to manipulate or extract sensitive data from the database.

This can lead to data breaches, unauthorized data modification, and potentially further compromise of the application or underlying systems.

Detection Guidance

This vulnerability can be detected by sending crafted HTTP requests to the dictionary authorization endpoint that include SQL injection payloads in the Password argument. For example, injecting boolean-based SQL payloads such as closing the password string and appending conditions like 'OR 1=1' can be used to test if the system improperly authorizes access.

A practical detection method involves sending a malformed password payload via an HTTP request and observing if the response indicates successful authorization (true) instead of rejection (false).

• Use curl or similar tools to send a request with a payload like: curl -X POST -d 'Password=anything' OR 1=1 http://target/application/PHP/objects/notes/accessing_dictionary_authorization.php
• Monitor network traffic for unusual or malformed SQL payloads targeting the Password parameter in requests to the Notes_controller::accessing_dictionary_authorization function.

Mitigation Strategies

Immediate mitigation steps include preventing the injection of untrusted input into SQL queries by properly sanitizing and parameterizing the Password argument in the affected function.

Since the vulnerability arises from improper use of the prepare() function allowing concatenation of untrusted input, ensure that all SQL queries use parameterized statements correctly without string concatenation.

If possible, restrict access to the vulnerable endpoint to trusted networks or users until a patch or update is available.

Monitor logs for suspicious authorization attempts that may indicate exploitation attempts.

Compliance Impact

The SQL injection vulnerability in the mjperpinosa stumasy application allows attackers to bypass password checks and potentially gain unauthorized access to sensitive data. This unauthorized access and potential data manipulation or extraction can lead to violations of data protection regulations such as GDPR and HIPAA, which require strict controls over access to personal and sensitive information.

Specifically, the vulnerability could result in unauthorized disclosure or alteration of protected data, undermining confidentiality, integrity, and availability requirements mandated by these standards.
