CVE-2009-0730 in Com Gigcalendar
Summary
by MITRE
Multiple SQL injection vulnerabilities in the GigCalendar (com_gigcal) component 1.0 for Mambo and Joomla!, when magic_quotes_gpc is disabled, allow remote attackers to execute arbitrary SQL commands via (1) the gigcal _venues_id parameter in a details action to index.php, which is not properly handled by venuedetails.php, and (2) the gigcal_bands_id parameter in a details action to index.php, which is not properly handled by banddetails.php, different vectors than CVE-2009-0726.

The vulnerability described in CVE-2009-0730 represents a critical SQL injection flaw within the GigCalendar component version 1.0 for Mambo and Joomla! platforms. This security weakness specifically targets the handling of user-supplied input parameters within the component's PHP scripts, creating opportunities for remote attackers to manipulate database queries and potentially gain unauthorized access to sensitive information. The vulnerability manifests when the PHP configuration setting magic_quotes_gpc is disabled, which removes the automatic escaping of special characters in GET, POST, and COOKIE data. This configuration allows malicious input to bypass basic sanitization mechanisms that would otherwise protect against SQL injection attacks.
The technical implementation of this vulnerability occurs through two distinct attack vectors that exploit improper parameter validation in the component's frontend handling scripts. The first vector targets the gigcal_venues_id parameter within the details action of the index.php script, where the venuedetails.php file fails to properly sanitize or escape user input before incorporating it into SQL queries. Similarly, the second vector exploits the gigcal_bands_id parameter through the banddetails.php script, which demonstrates the same inadequate input handling behavior. Both vectors represent classic SQL injection vulnerabilities where attacker-controlled data flows directly into database commands without proper sanitization, allowing for command injection that can manipulate, retrieve, or delete database contents.
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 underlying database server. This could enable full database compromise, allowing unauthorized users to extract sensitive information including user credentials, personal data, and system configuration details. The vulnerability's exploitation requires minimal privileges and can be executed remotely without authentication, making it particularly dangerous for web applications that store sensitive data. Attackers could potentially escalate their access to gain administrative control over the entire application or even the underlying server, depending on database permissions and server configuration.
Security professionals should recognize this vulnerability as a direct violation of CWE-89, which specifically addresses SQL injection weaknesses in software applications. The attack patterns align with those documented in the MITRE ATT&CK framework under the technique of "SQL Injection" (T1071.005), where adversaries leverage application vulnerabilities to manipulate database queries and extract sensitive information. The vulnerability demonstrates poor input validation practices and highlights the critical importance of proper parameter sanitization in web applications. Organizations should immediately implement mitigations including input validation, parameterized queries, and proper output escaping to prevent exploitation of this vulnerability. Additionally, the vulnerability underscores the necessity of keeping CMS platforms and third-party components updated, as outdated software often contains known vulnerabilities that attackers can readily exploit. The presence of this vulnerability in widely-used platforms like Mambo and Joomla! emphasizes the importance of security audits and the implementation of web application firewalls to detect and prevent such attacks.
