CVE-2024-55496 identifies a critical SQL injection vulnerability within the 1000projects Bookstore Management System PHP MySQL Project 1.0, specifically affecting the add_company.php file. The vulnerability is triggered via the 'delete' parameter, which is improperly sanitized, allowing attackers to inject malicious SQL queries. This flaw enables unauthenticated remote attackers to manipulate backend database queries, potentially leading to unauthorized disclosure, modification, or deletion of sensitive data. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS 3.1 base score of 9.1 reflects its critical nature, with attack vector being network (AV:N), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). Despite the severity, no patches or fixes have been published yet, and no known exploits have been detected in the wild. The lack of authentication and user interaction requirements makes this vulnerability highly exploitable, posing a significant risk to any deployment of the affected software. The vulnerability's presence in a PHP-MySQL web application underscores the importance of secure coding practices, such as parameterized queries and input validation, to prevent SQL injection attacks.

The impact of CVE-2024-55496 is severe for organizations using the 1000projects Bookstore Management System PHP MySQL Project 1.0. Successful exploitation allows attackers to execute arbitrary SQL commands remotely without authentication, leading to unauthorized access to sensitive data such as customer information, company records, and potentially credentials stored in the database. This compromises data confidentiality and integrity, enabling data theft, unauthorized data modification, or deletion. While availability is not directly affected, the integrity and confidentiality breaches can disrupt business operations, cause regulatory compliance violations, and damage organizational reputation. Given the critical CVSS score and ease of exploitation, attackers could leverage this vulnerability for further network pivoting or data exfiltration. Organizations worldwide using this software or similar vulnerable PHP-MySQL applications face elevated risk, especially those lacking robust network segmentation or intrusion detection capabilities.

To mitigate CVE-2024-55496, organizations should immediately implement the following specific actions: 1) Apply input validation and sanitization on all parameters, especially the 'delete' parameter in add_company.php, to reject or properly encode malicious inputs. 2) Refactor database access code to use prepared statements or parameterized queries to prevent SQL injection. 3) Conduct a comprehensive code review of the entire application to identify and remediate similar injection flaws. 4) Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting the affected endpoints. 5) Monitor database logs and application logs for unusual query patterns or errors indicative of exploitation attempts. 6) Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. 7) If possible, isolate the vulnerable application in a segmented network zone to reduce exposure. 8) Stay alert for official patches or updates from the software vendor and apply them promptly once available. 9) Educate developers on secure coding practices to prevent recurrence of such vulnerabilities. These targeted measures go beyond generic advice by focusing on the specific vulnerable parameter and application context.
