CVE-2010-1522 in Com Booklibrary
Summary
by MITRE
Multiple SQL injection vulnerabilities in the BookLibrary Basic (com_booklibrary) component 1.5.3 before 1.5.3_2010_06_20 for Joomla! allow remote attackers to execute arbitrary SQL commands via the bid[] parameter in a (1) lend_request or (2) save_lend_request action to index.php, the id parameter in a (3) mdownload or (4) downitsf action to index.php, or (5) the searchtext parameter in a search action to index.php.

The CVE-2010-1522 vulnerability represents a critical SQL injection flaw in the BookLibrary Basic component for Joomla web applications, making it a significant target for attackers seeking to compromise Joomla! installations.
The technical implementation of this vulnerability occurs through five distinct parameter manipulation points within the component's request handling. The bid[] parameter in lend_request and save_lend_request actions to index.php provides the first vector, where unsanitized array inputs are directly incorporated into SQL query construction without proper escaping or parameterization. Similarly, the id parameter in mdownload and downitsf actions creates additional exposure points where integer values are blindly concatenated into database queries. The fifth vulnerability manifests through the searchtext parameter in search actions, where user-supplied search terms bypass input validation mechanisms and are directly embedded into SQL statements, allowing attackers to inject malicious SQL payloads that can manipulate or extract database information.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to execute arbitrary commands on the database server through SQL injection techniques. This capability allows for complete database compromise including data extraction, modification, or deletion, potentially leading to full system compromise when combined with other vulnerabilities or when the database server has elevated privileges. Attackers can leverage these vulnerabilities to escalate privileges, create backdoors, or establish persistent access to the compromised Joomla ecosystem.
Mitigation strategies for CVE-2010-1522 should focus on immediate component updates to version 1.5.3_2010_06_20 or later, which contain proper input validation and sanitization mechanisms. Organizations should implement proper parameterized queries and prepared statements to prevent SQL injection attacks, ensuring that all user inputs are properly escaped or validated before database interaction. Network-based protections including web application firewalls and intrusion detection systems can provide additional layers of defense, while regular security audits and vulnerability assessments should be conducted to identify similar issues in other components. The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws, and maps to ATT&CK technique T1190 for exploiting vulnerabilities in web applications, highlighting the need for comprehensive security measures beyond simple patching.
This vulnerability demonstrates the critical importance of input validation in web application security, particularly within content management systems where components often handle user-supplied data without adequate sanitization. The multiple attack vectors present in this vulnerability underscore the need for comprehensive security testing and the implementation of secure coding practices throughout the application development lifecycle. Organizations should establish robust patch management processes and maintain current knowledge of security vulnerabilities affecting their deployed applications to prevent exploitation of known weaknesses. The impact of such vulnerabilities extends beyond immediate data compromise to potentially affect the entire infrastructure, making proactive security measures essential for protecting web applications and their underlying databases from unauthorized access and manipulation.
