The CVE-2010-4923 vulnerability represents a critical SQL injection flaw within the Virtue Book Store web application, specifically affecting the book/detail.php component. This vulnerability resides in the handling of user-supplied input through the bid parameter, which is used to retrieve and display book details from a database. The flaw allows malicious actors to manipulate the SQL query structure by injecting malicious SQL code through the bid parameter, potentially gaining unauthorized access to the underlying database system. Such vulnerabilities are particularly dangerous as they can enable attackers to extract sensitive information, modify database contents, or even escalate privileges within the application's database environment. The vulnerability directly impacts the application's integrity and confidentiality by undermining the security controls designed to protect database interactions from malicious input.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization practices within the Virtue Book Store application. When the bid parameter is processed in the book/detail.php script, the application fails to properly escape or validate user input before incorporating it into SQL queries. This lack of proper input sanitization creates an opening for attackers to inject malicious SQL payloads that can manipulate the database query execution flow. The vulnerability aligns with CWE-89, which categorizes SQL injection as a fundamental weakness in software applications where user-supplied data is directly incorporated into SQL commands without proper sanitization. Attackers can exploit this by crafting specific bid parameter values that contain SQL injection payloads, potentially leading to unauthorized database access and data manipulation.
The operational impact of CVE-2010-4923 extends beyond simple data theft to encompass potential system compromise and business disruption. Remote attackers can leverage this vulnerability to access sensitive customer information, book inventory details, and potentially administrative credentials stored within the database. The vulnerability enables attackers to perform unauthorized data read operations, write operations, and even execute destructive commands against the database. This poses significant risks to the organization's data integrity and can result in compliance violations, regulatory penalties, and reputational damage. The vulnerability also provides a potential foothold for further attacks within the network infrastructure, as database credentials and system information can be extracted to facilitate lateral movement. According to ATT&CK framework, this vulnerability maps to T1071.005 for application layer protocol usage and T1190 for exploitation of remote services, demonstrating how attackers can leverage this weakness to establish persistent access and escalate privileges.
Mitigation strategies for CVE-2010-4923 should focus on implementing robust input validation and parameterized queries to prevent SQL injection attacks. Organizations should immediately apply the vendor-supplied patches or updates that address this vulnerability in the Virtue Book Store application. The implementation of prepared statements or parameterized queries in the book/detail.php script would effectively prevent malicious SQL code from being executed. Additionally, input validation should be strengthened to ensure that the bid parameter only accepts expected data types and formats. Network-level protections such as web application firewalls and intrusion prevention systems can provide additional layers of defense against exploitation attempts. Regular security testing including automated vulnerability scanning and manual penetration testing should be conducted to identify and remediate similar vulnerabilities. The organization should also implement proper database access controls, including least privilege principles, to limit the potential damage from successful exploitation attempts. According to industry best practices and NIST guidelines, organizations must maintain up-to-date vulnerability management processes to address known weaknesses like CVE-2010-4923 and prevent unauthorized database access.
