Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: CERT VDE

Description

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 inmessage model that can be exploited by a low privileged remote attacker. It occurs because special elements in a SQL DELETE command are not properly neutralized, allowing the attacker to read the entire database and delete entries in a non-critical table.

Impact Analysis

Exploiting this vulnerability can lead to a total loss of confidentiality, meaning sensitive data in the database can be fully exposed. Additionally, there can be some loss of integrity due to the deletion of entries in a non-critical table.

Compliance Impact

This vulnerability can result in a total loss of confidentiality and some loss of integrity due to an unauthenticated SQL Injection allowing reading of the whole database and deletion of entries in a non-critical table.

Such a loss of confidentiality and integrity could negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive data and maintaining data integrity.
