Assigner: Joomla! Project

Description
Joomla Extension - phoca.cz - Unauthenticated SQL injection via attribute filter in Phoca Cart 5.0.0-6.1.6 - The a[] (attribute) and s[] (specification) GET array parameters on Phoca Cart's public shop items page are concatenated raw into SQL WHERE clauses without parameterization or escaping. An unauthenticated attacker can inject arbitrary SQL through these parameters, enabling full database extraction via time-based blind techniques.

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

This is an unauthenticated SQL injection vulnerability in the Joomla extension Phoca Cart versions 5.0.0 to 6.1.16. Attackers can exploit it by sending crafted GET requests with the parameters a[] (attribute) or s[] (specification) to the public shop items page. These parameters are directly concatenated into SQL WHERE clauses without proper sanitization, allowing arbitrary SQL code execution. The flaw enables full database extraction through time-based blind techniques.

Detection Guidance

To detect this vulnerability, monitor HTTP GET requests to Phoca Cart's shop items page for unusual parameters like a[] or s[] with SQL-like payloads. Use tools like Wireshark or tcpdump to capture traffic. Check server logs for repeated requests with these parameters. Test with simple payloads like a[]=1' OR '1'='1 to see if responses are delayed or return unexpected data.

Impact Analysis

An attacker could steal sensitive data such as user credentials, personal information, payment details, or confidential business data stored in the database. They might also modify or delete database records, leading to data corruption or loss. Since no authentication is required, any visitor to the affected website could potentially exploit this vulnerability.

Compliance Impact

This vulnerability could lead to severe compliance violations. Under GDPR, unauthorized data access or exfiltration may result in fines up to 4% of global revenue or 20 million euros. For HIPAA, exposure of protected health information could trigger penalties and mandatory breach notifications. Organizations must address this flaw promptly to avoid regulatory penalties and reputational damage.

Mitigation Strategies

Immediately update Phoca Cart to the latest version (6.1.17 or higher) to patch the SQL injection flaw. If updating is not possible, disable the Phoca Cart component temporarily. Implement a web application firewall (WAF) to block malicious requests containing a[] or s[] parameters. Review and restrict database user permissions to limit damage from potential exploits.
