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.

Executive Summary

This vulnerability is an SQL Injection issue in the Tainacan software, specifically versions up to 1.0.3. It involves improper neutralization of special elements used in SQL commands, allowing an attacker to perform Blind SQL Injection attacks.

Impact Analysis

The vulnerability has a high severity score (CVSS 9.3) and can allow an attacker to execute unauthorized SQL commands remotely without any privileges or user interaction. This can lead to high confidentiality impact by exposing sensitive data and a low availability impact by potentially disrupting the service.

Compliance Impact

The vulnerability is a Blind SQL Injection in Tainacan versions up to 1.0.3, which allows an attacker to extract sensitive information from the database without authorization.

Such unauthorized data access can lead to breaches of confidentiality and data integrity, potentially resulting in violations of data protection regulations like GDPR and HIPAA that require safeguarding personal and sensitive information.

Therefore, this vulnerability could negatively impact compliance with these standards by exposing protected data to attackers.
