Compliance Impact

The vulnerability allows attackers to bypass authentication, retrieve password hashes, and gain administrative access with full system privileges, which can lead to unauthorized access to sensitive personal data and compromise physical security controls. Such unauthorized access and data exposure could result in non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and breaches.

Executive Summary

The SOCA Access Control System version 180612 contains multiple SQL injection vulnerabilities in its PHP web application. These vulnerabilities occur because several POST parameters are not properly sanitized before being used in SQL queries. Attackers can exploit these flaws to manipulate SQL queries arbitrarily, bypass authentication mechanisms, retrieve password hashes, and gain unauthorized administrative access with full system privileges. This allows attackers to bypass both digital and physical access controls managed by the system. [2, 3]

Impact Analysis

Exploiting these SQL injection vulnerabilities can allow attackers to bypass authentication, retrieve MD5 password hashes, and log in with the highest privileges. This means attackers can gain full administrative access to the system, potentially unlocking doors and bypassing physical access controls such as proximity and fingerprint systems, electric locks, and keyless entry systems. The risk level is rated very high due to exposure of sensitive information and potential manipulation of data. [2, 3]

Detection Guidance

This vulnerability can be detected by testing for SQL injection in the vulnerable POST parameters such as 'ID' in Login.php and 'cidx' in Card_Edit_GetJson.php. You can use tools like sqlmap or manual curl commands to send crafted POST requests with SQL injection payloads such as "' or 1=1--" to these endpoints and observe if authentication is bypassed or sensitive data is returned. For example, a curl command to test authentication bypass might be: curl -X POST -d "ID=' or 1=1--" http://target/Login.php. Monitoring unusual authentication bypass or unexpected data retrieval in logs can also help detect exploitation attempts. [3]

Mitigation Strategies

Immediate mitigation steps include restricting network access to the vulnerable SOCA Access Control System web interfaces, applying input validation and sanitization on all POST parameters to prevent SQL injection, and updating or patching the system if a vendor fix is available. Additionally, monitoring logs for suspicious activity and changing all passwords after a suspected compromise are recommended. If patching is not immediately possible, consider deploying a web application firewall (WAF) to block SQL injection attempts targeting the vulnerable parameters. [2, 3]
