Compliance Impact

The SQL injection vulnerability in Joomla! Component PHP-Bridge 1.2.3 allows unauthenticated attackers to extract sensitive database information, including table and column names. This exposure of sensitive data could lead to unauthorized access to personal or protected information, potentially violating data protection regulations such as GDPR or HIPAA.

By enabling attackers to execute arbitrary SQL queries and extract database contents, the vulnerability increases the risk of data breaches, which are subject to strict compliance requirements under these standards.

Executive Summary

Joomla! Component PHP-Bridge version 1.2.3 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the 'id' parameter.

Attackers can send specially crafted GET requests to index.php with parameters option=com_phpbridge and view=phpview, manipulating the 'id' parameter to extract sensitive database information such as table and column names.

This vulnerability is due to improper neutralization of special elements in SQL commands, classified under CWE-89.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary SQL queries on the affected Joomla! component without authentication.

As a result, attackers can extract sensitive database information including table and column names, potentially leading to data leakage.

Such unauthorized access to database contents can compromise the confidentiality and integrity of your data.

Detection Guidance

This vulnerability can be detected by monitoring for suspicious GET requests targeting the vulnerable Joomla! component, specifically requests to index.php with parameters option=com_phpbridge and view=phpview, where the id parameter contains potentially malicious SQL code.

A practical detection method is to look for HTTP requests matching the pattern: /index.php?option=com_phpbridge&view=phpview&run=fahrzeuge&mode=detail&id=[SQL injection payload].

You can use network monitoring tools or web server logs to search for such requests.

• Use grep or similar tools on web server logs to find suspicious requests, for example:
• grep "option=com_phpbridge&view=phpview" /var/log/apache2/access.log | grep "id="
• Use curl or wget to test the vulnerability by sending crafted GET requests with SQL injection payloads in the id parameter, for example:
• curl "http://target-site/index.php?option=com_phpbridge&view=phpview&run=fahrzeuge&mode=detail&id=1' UNION SELECT NULL--"

Mitigation Strategies

Immediate mitigation steps include restricting or blocking access to the vulnerable component by disabling or removing the PHP-Bridge component version 1.2.3 from your Joomla! installation.

If removal is not immediately possible, implement web application firewall (WAF) rules to block requests containing suspicious SQL injection patterns in the id parameter targeting option=com_phpbridge&view=phpview.

Additionally, monitor logs for exploitation attempts and apply any available patches or updates from the component developer or Joomla! extensions directory.
