Executive Summary

Kados R10 GreenBee contains a high-severity SQL injection vulnerability in the update_feature.php file. This vulnerability arises because the feature_id parameter is directly concatenated into SQL statements without proper sanitization.

Unauthenticated attackers can exploit this flaw by sending a crafted GET request with a UNION-based payload through the feature_id parameter. This allows them to execute arbitrary SQL commands on the database.

As a result, attackers can extract sensitive database information such as the current user, database name, and DBMS version.

Impact Analysis

This vulnerability can have significant impacts because it allows unauthenticated attackers to execute arbitrary SQL commands on the database.

• Attackers can extract sensitive information from the database, including user credentials and database details.
• The integrity of the database can be compromised, potentially leading to data leakage.
• Since the vulnerability requires no authentication, it increases the risk of unauthorized access and data exposure.

Detection Guidance

This vulnerability can be detected by monitoring for suspicious GET requests targeting the update_feature.php file, specifically those including the feature_id parameter with unusual or crafted SQL payloads.

A practical detection method is to use network traffic inspection or web server logs to identify requests with UNION-based SQL injection patterns in the feature_id parameter.

For example, you can use the following command to search web server logs for suspicious requests:

• grep -i 'update_feature.php' /var/log/apache2/access.log | grep 'feature_id=.*UNION'

Additionally, tools like sqlmap can be used to test the vulnerability by targeting the feature_id parameter with automated SQL injection payloads.

Mitigation Strategies

Immediate mitigation steps include applying input validation and sanitization on the feature_id parameter to prevent SQL injection.

If a patch or update is available from the vendor, it should be applied promptly to fix the vulnerability.

As a temporary measure, you can block or filter HTTP requests containing suspicious SQL injection patterns targeting update_feature.php at the web application firewall or network perimeter.

Review and restrict database permissions to limit the impact of any successful injection.

Compliance Impact

The SQL injection vulnerability in Kados R10 GreenBee allows unauthenticated attackers to extract sensitive database information, including current user data and database details. Such unauthorized access to sensitive information can lead to violations of data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive data against unauthorized access and breaches.

By enabling attackers to retrieve sensitive information through SQL injection, this vulnerability increases the risk of data breaches, potentially resulting in non-compliance with standards that require strict data confidentiality, integrity, and security controls.
