The CVE-2010-0795 vulnerability represents a critical sql injection flaw within the JE Event Calendars component version 1.0 for Joomla! platforms. This vulnerability specifically targets the event_id parameter within the event action handler located at index.php, creating an exploitable pathway for malicious actors to manipulate the underlying database operations. The vulnerability stems from insufficient input validation and improper parameter sanitization within the component's code implementation, allowing attackers to inject malicious sql payloads that bypass normal security controls.
The technical exploitation of this vulnerability occurs through the manipulation of the event_id parameter in the url structure when accessing calendar events through the Joomla! framework. When the component processes this parameter without adequate sanitization, it directly incorporates user-supplied input into sql query construction, enabling attackers to construct malicious sql statements that can be executed within the context of the database connection. This type of vulnerability falls under the common weakness enumeration category CWE-89 sql injection, which is classified as a high severity issue in the owasp top ten web application security risks.
The operational impact of this vulnerability extends beyond simple data theft or modification, 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 including data exfiltration, unauthorized user account creation, privilege escalation, and potential system compromise. Attackers could leverage this vulnerability to gain persistent access to the underlying database, potentially leading to broader network infiltration as database credentials are often shared across multiple systems within the same infrastructure. The vulnerability is particularly dangerous in web applications where the database connection operates with elevated privileges, as this could enable attackers to perform administrative operations on the database itself.
Mitigation strategies for CVE-2010-0795 require immediate action through component updates and proper input validation implementation. Organizations should prioritize upgrading to the latest version of the JE Event Calendars component where the vulnerability has been patched and sql injection protections have been implemented. Additionally, implementing proper parameterized queries and input sanitization techniques within the application code can prevent similar vulnerabilities from occurring in the future. Security measures should include web application firewalls that can detect and block sql injection patterns, database access logging for monitoring suspicious activities, and regular security assessments to identify potential injection points within the application framework. The vulnerability also highlights the importance of following secure coding practices such as those outlined in the owasp secure coding guidelines, which emphasize the need for proper input validation and output encoding to prevent injection attacks.
