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

Joomla! Component KissGallery version 1.0.0 contains a high-severity SQL injection vulnerability. This flaw allows unauthenticated attackers to inject malicious SQL commands through the component's URL path, specifically via the 'kissgallery' endpoint.

By exploiting this vulnerability, attackers can execute arbitrary database queries and potentially extract sensitive information from the database.

Impact Analysis

This vulnerability can have significant impacts as it allows attackers to execute arbitrary SQL commands on the database without authentication.

  • Attackers can extract sensitive information from the database.
  • It can lead to unauthorized data access and potential data breaches.
  • The integrity of the database could be compromised by malicious queries.
Detection Guidance

This vulnerability can be detected by testing the Joomla! site for SQL injection attempts targeting the KissGallery component's URL path, specifically the 'kissgallery' endpoint.

A common method is to send crafted HTTP requests with SQL injection payloads appended to the kissgallery URL path and observe the responses for database errors or unexpected data.

For example, you can use curl or similar tools to test the endpoint:

  • curl -i "http://your-joomla-site/kissgallery/1' OR '1'='1"
  • curl -i "http://your-joomla-site/kissgallery/1' UNION SELECT NULL--"

If the server responds with SQL errors or unusual output, it indicates the presence of the SQL injection vulnerability.

Mitigation Strategies

The immediate mitigation step is to remove or disable the vulnerable KissGallery component from your Joomla! installation.

Since the extension has been unpublished and flagged as vulnerable, users are advised to avoid using it and seek alternative gallery extensions.

Additionally, ensure your Joomla! installation and all extensions are kept up to date with the latest security patches.

Monitor Joomla! security advisories and community resources for updates or patches related to this vulnerability.

Compliance Impact

The SQL injection vulnerability in Joomla! Component KissGallery 1.0.0 allows attackers to extract sensitive information from the database. Such unauthorized access to sensitive data can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and breaches.

Organizations using this vulnerable component risk exposing confidential data, potentially resulting in violations of privacy and security requirements mandated by these standards.
