The vulnerability identified as CVE-2010-4363 represents a critical SQL injection flaw within the MRCGIGUY (MCG) FreeTicket 1.0.0 web application. This vulnerability specifically affects the contact.php script and manifests when the PHP configuration parameter magic_quotes_gpc is disabled, creating a dangerous condition where user input is not properly sanitized before being incorporated into database queries. The flaw enables remote attackers to manipulate the application's database operations through carefully crafted input parameters.
The technical exploitation of this vulnerability occurs through two primary vectors within the showtickets action of the contact.php script. Attackers can manipulate the id parameter and the email parameter to inject malicious SQL code that bypasses normal input validation mechanisms. When magic_quotes_gpc is disabled, the application fails to automatically escape special characters in user input, allowing attackers to inject SQL syntax that gets executed by the underlying database engine. This creates a direct pathway for unauthorized database access and manipulation.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to execute arbitrary SQL commands on the affected database server. Successful exploitation could result in complete database compromise, data exfiltration, modification of critical information, or even privilege escalation within the database environment. The vulnerability affects the application's integrity and confidentiality, potentially exposing sensitive user information including personal details and contact information stored in the database. Attackers could also leverage this vulnerability to establish persistent access or deploy additional malicious payloads.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-89 SQL Injection, which is classified as a high-risk weakness in the Common Weakness Enumeration catalog. The ATT&CK framework categorizes this as a Database Operations technique under the Execution phase, where adversaries leverage application vulnerabilities to execute commands on database servers. The vulnerability demonstrates poor input validation practices and inadequate sanitization of user-supplied data, which are fundamental security controls that should be implemented at multiple layers of application architecture. Organizations should implement proper parameterized queries, input validation, and output encoding to prevent such vulnerabilities from being exploited in production environments.
Mitigation strategies for this vulnerability include immediately enabling magic_quotes_gpc or implementing proper input sanitization and parameterized queries, updating to a patched version of the MCG FreeTicket application, and implementing web application firewalls to detect and block malicious SQL injection attempts. Additionally, regular security assessments and code reviews should be conducted to identify and remediate similar input validation weaknesses across the entire application stack.
