The vulnerability identified as CVE-2011-0511 represents a critical SQL injection flaw within the allCineVid component version 1.0.0 for Joomla! platforms. This vulnerability resides in the component's handling of user input through the id parameter in the index.php file, creating a pathway for malicious actors to manipulate database queries. The flaw stems from inadequate input validation and sanitization practices within the component's code structure, allowing attackers to inject malicious SQL commands that bypass normal authentication and authorization mechanisms.
The technical exploitation of this vulnerability occurs when an attacker submits a crafted id parameter value that contains SQL payload code. The component fails to properly escape or validate this input before incorporating it into database queries, enabling the attacker to manipulate the underlying SQL execution flow. This allows for unauthorized database access, data manipulation, and potentially complete system compromise. The vulnerability is classified under CWE-89 as SQL injection, which represents one of the most prevalent and dangerous web application security flaws in the industry. The attack vector operates entirely through HTTP requests, making it accessible to remote threat actors without requiring local system access or elevated privileges.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to execute arbitrary code on the affected Joomla installations running version 1.0.0 of the allCineVid component, which could be present in numerous web applications across various industries. From an ATT&CK framework perspective, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) as attackers can leverage the component's web interface to execute their malicious payloads. The vulnerability's remote exploitability and lack of authentication requirements make it particularly dangerous for organizations with exposed web applications.
Mitigation strategies for CVE-2011-0511 should prioritize immediate component updates or patches provided by the Joomla installations, as this vulnerability demonstrates the importance of maintaining current software versions to protect against known exploits.
