CVE-2023-30558 : Security Advisory and Response

Understanding CVE-2023-30558

Archery, an open-source SQL audit platform, is impacted by multiple SQL injection vulnerabilities in the

sql/data_dictionary.py

file. These vulnerabilities could enable attackers to query connected databases by exploiting improper neutralization of special elements in SQL commands.

What is CVE-2023-30558?

Archery project contains multiple SQL injection vulnerabilities due to unsafe handling of user input in certain methods. This may lead to unauthorized access to databases through malicious SQL queries.

The Impact of CVE-2023-30558

The vulnerabilities in Archery could result in a significant impact on confidentiality as an attacker could extract sensitive information from databases. The overall severity is rated as medium, with a base score of 6.5.

Technical Details of CVE-2023-30558

The vulnerability arises from unsafe concatenation of user input into SQL queries in the

table_list

method within the Archery project. The issues are present in

sql/engines/mssql.py

and

sql/engines/oracle.py

files, enabling attackers to execute malicious SQL commands.

Vulnerability Description

User input from the

db_name

parameter is not properly sanitized and is directly used in SQL queries, leading to SQL injection vulnerabilities. This can be exploited to perform unauthorized actions on the database.

Affected Systems and Versions

The vulnerability affects Archery versions up to 1.9.0, exposing systems that utilize these versions to potential exploitation through SQL injection attacks.

Exploitation Mechanism

By injecting SQL commands into the

db_name

parameter in the

table_list

method, attackers can manipulate the SQL queries executed by the database engines, potentially extracting or modifying sensitive data.

Mitigation and Prevention

To address CVE-2023-30558, immediate steps should be taken to secure systems and prevent unauthorized access to databases.

Immediate Steps to Take

Developers should sanitize user input and implement prepared statements when executing SQL queries to prevent SQL injection attacks. It is crucial to update Archery to a patched version that addresses these vulnerabilities.

Long-Term Security Practices

Implement secure coding practices to validate and sanitize user input effectively across all input fields in the application. Regular security audits and testing can help identify and remediate vulnerabilities.

Patching and Updates

Stay informed about security advisories and patches released by the Archery project. Apply updates promptly to mitigate the risk of SQL injection attacks.
