CVE-2010-2515 in Com Jfaq
Summary
by MITRE
Multiple SQL injection vulnerabilities in index.php in the JFaq (com_jfaq) component 1.2 for Joomla!, when magic_quotes_gpc is disabled, allow (1) remote attackers to execute arbitrary SQL commands via the id parameter, and (2) remote authenticated users with "Public Front-end" permissions to execute arbitrary SQL commands via the titlu parameter (title field). NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2010-2515 represents a critical SQL injection flaw within the JFaq component version 1.2 for Joomla! platforms. This vulnerability specifically targets the index.php file and exploits a fundamental weakness in input validation mechanisms when the PHP configuration parameter magic_quotes_gpc is disabled. The flaw manifests in two distinct attack vectors that collectively enable malicious actors to gain unauthorized access to underlying database systems through carefully crafted SQL commands.
The technical implementation of this vulnerability stems from improper sanitization of user-supplied input parameters within the Joomla! component. When magic_quotes_gpc is disabled, the web application fails to properly escape special characters in user input, creating an environment where attackers can inject malicious SQL code directly into database queries. The first attack vector targets the id parameter, allowing remote unauthenticated attackers to manipulate database operations through direct SQL injection. The second vector exploits the titlu parameter, which affects authenticated users with "Public Front-end" permissions, demonstrating how privilege escalation can occur through carefully constructed input manipulation.
From an operational impact perspective, this vulnerability creates significant risk for Joomla! websites utilizing the affected JFaq component. Attackers can execute arbitrary SQL commands to extract sensitive data, modify database contents, or even escalate privileges within the application environment. The vulnerability's severity is amplified by the fact that it affects both anonymous and authenticated users, potentially allowing attackers to compromise database integrity and confidentiality. The attack surface extends beyond simple data theft to include potential system compromise through database-level attacks that could lead to further exploitation within the hosting environment.
Security professionals should note that this vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications. The flaw also maps to ATT&CK technique T1071.004, covering application layer protocol manipulation, and T1046, covering network service scanning. Organizations should implement immediate mitigations including disabling the vulnerable component, applying available security patches, and implementing proper input validation measures. The vulnerability demonstrates the critical importance of proper parameter sanitization and the dangers of relying on server configuration settings for security enforcement rather than implementing robust application-level protections. Additionally, this issue highlights the necessity of regular security assessments and the importance of maintaining up-to-date software components to prevent exploitation of known vulnerabilities in content management systems.
