Compliance Impact

The vulnerability allows unauthenticated attackers to extract sensitive database information by exploiting an SQL injection flaw in the Joomla! Component jCart for OpenCart. Such unauthorized access to sensitive data can lead to violations of data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive information.

Because attackers can manipulate database queries and potentially access confidential data without authorization, organizations using the affected software may fail to meet compliance requirements related to data confidentiality, integrity, and security.

Executive Summary

The Joomla! Component jCart for OpenCart 2.0 contains a high-severity SQL injection vulnerability identified as CVE-2017-20282. This vulnerability allows unauthenticated attackers to manipulate database queries by injecting malicious SQL code through the 'product_id' parameter.

Attackers can exploit this flaw by sending specially crafted GET requests to 'index.php' with parameters option=com_jcart and route=product/product, along with malicious 'product_id' values. This enables them to extract sensitive information from the database.

Detection Guidance

This SQL injection vulnerability can be detected by monitoring for suspicious GET requests targeting the vulnerable endpoint with crafted 'product_id' parameters.

Specifically, look for HTTP GET requests to 'index.php' with parameters 'option=com_jcart&route=product/product' and unusual or malicious values in the 'product_id' parameter.

A simple detection command using curl to test the vulnerability might be:

• curl -i "http://[target]/index.php?option=com_jcart&route=product/product&product_id=1' OR '1'='1"

Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such suspicious SQL injection patterns in URLs.

Mitigation Strategies

Immediate mitigation steps include restricting access to the vulnerable component and sanitizing input parameters.

Specifically, you should:

• Apply any available patches or updates to the Joomla! Component jCart for OpenCart to fix the SQL injection vulnerability.
• Implement input validation and parameterized queries to prevent SQL injection through the 'product_id' parameter.
• Use a web application firewall (WAF) to block malicious requests targeting 'option=com_jcart&route=product/product' with suspicious 'product_id' values.
• Restrict network access to the affected endpoints if possible, limiting exposure to untrusted users.
