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 unauthenticated SQL Injection in the sync_data24 task. It occurs because special elements in a SQL SELECT command are not properly neutralized, allowing a remote attacker to inject malicious SQL code without needing to authenticate.

Impact Analysis

Exploiting this vulnerability can lead to a total loss of confidentiality, meaning an attacker could access sensitive data without authorization.

Compliance Impact

This vulnerability allows an unauthenticated remote attacker to exploit an SQL Injection flaw resulting in a total loss of confidentiality.

Loss of confidentiality can lead to unauthorized access to sensitive personal or protected health information, which may cause non-compliance with data protection regulations such as GDPR and HIPAA.

Therefore, this vulnerability poses a significant risk to compliance with standards that require safeguarding confidentiality of data.
