The vulnerability identified as CVE-2010-4927 represents a critical SQL injection flaw within the Restaurant Guide component version 1.0.0 for Joomla! platforms. This security weakness resides in the component's handling of user input through the id parameter when processing country actions directed to the index.php endpoint. The flaw enables malicious actors to manipulate database queries by injecting arbitrary SQL commands, potentially compromising the entire underlying database infrastructure. Such vulnerabilities are particularly dangerous in content management systems where components often handle sensitive data and user interactions.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the component's codebase. When the country action processes the id parameter, the application fails to properly escape or validate user-supplied data before incorporating it into SQL query constructs. This primitive approach to data handling creates an exploitable entry point where attackers can craft malicious payloads that bypass normal security controls. The vulnerability specifically manifests when the id parameter is manipulated to inject SQL syntax that alters the intended query execution flow. According to CWE classification, this represents a CWE-89: Improper Neutralization of Special Elements used in an SQL Command, which is a fundamental weakness in database query construction.
The operational impact of this vulnerability extends far beyond simple data manipulation, as it provides attackers with the capability to execute arbitrary database commands remotely. Successful exploitation could enable attackers to extract sensitive information including user credentials, personal data, and administrative access details. The compromised system might also suffer from data corruption, unauthorized modifications, or complete database compromise. In a typical attack scenario, an attacker would construct a malicious URL containing SQL injection payloads targeting the vulnerable id parameter, potentially escalating privileges and gaining unauthorized access to the Joomla! administration interface. This vulnerability aligns with ATT&CK technique T1071.004: Application Layer Protocol: DNS, as attackers often leverage web application vulnerabilities to establish persistent access and exfiltrate data through database interactions.
Mitigation strategies for CVE-2010-4927 require immediate attention through multiple defensive measures. The primary recommendation involves upgrading the Restaurant Guide component to a patched version that implements proper input validation and parameterized queries. Organizations should also implement web application firewalls that can detect and block common SQL injection patterns targeting known vulnerable parameters. Additionally, database access controls should be reviewed to ensure that application accounts have minimal required privileges and that sensitive data is properly protected. Security monitoring should include detection of unusual database query patterns and unauthorized access attempts. The remediation process should follow the principle of least privilege, ensuring that database connections used by the Joomla! application have restricted permissions and that all user inputs are properly escaped before database interaction occurs. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other components or plugins that might present analogous attack vectors.
