CVE-2024-51326 is a SQL Injection vulnerability identified in projectworlds Travel Management System version 1.0. The vulnerability resides in the 't2' parameter within the deletesubcategory.php file, which fails to properly sanitize user input before incorporating it into SQL queries. This flaw allows a remote attacker to inject malicious SQL code, potentially leading to arbitrary code execution on the backend database server. The vulnerability requires no authentication or user interaction, making it highly accessible to attackers over the network. The CVSS 3.1 base score is 7.5, reflecting high severity due to the ease of exploitation (attack vector network, low complexity) and the impact on confidentiality (high), though integrity and availability are not affected. While no public exploits have been reported yet, the vulnerability aligns with CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The absence of official patches necessitates immediate mitigation efforts. This vulnerability could be leveraged to extract sensitive data from the database, potentially exposing personal or business-critical information managed by the travel system.

The primary impact of CVE-2024-51326 is unauthorized disclosure of sensitive data managed by the Travel Management System, which could include customer information, travel itineraries, payment details, and internal categorization data. Although the vulnerability does not directly affect data integrity or availability, the exposure of confidential information can lead to privacy violations, regulatory non-compliance, reputational damage, and potential financial losses. Attackers exploiting this vulnerability remotely and without authentication increase the risk profile significantly. Organizations relying on this system for travel management may face targeted attacks aiming to harvest data or gain footholds for further network intrusion. The lack of known exploits in the wild currently limits immediate widespread impact but also means organizations should proactively address the vulnerability before exploitation becomes common.

Given the absence of an official patch, organizations should implement the following specific mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 't2' parameter in deletesubcategory.php. 2) Conduct immediate code reviews and apply input validation and parameterized queries or prepared statements to sanitize all user inputs, especially the 't2' parameter. 3) Restrict database user permissions to the minimum necessary to limit the impact of any injection attack. 4) Monitor logs for unusual query patterns or repeated access attempts to deletesubcategory.php. 5) If possible, temporarily disable or restrict access to the vulnerable deletesubcategory.php functionality until a patch or secure update is available. 6) Educate development teams on secure coding practices to prevent similar vulnerabilities. 7) Plan for rapid deployment of official patches once released by projectworlds.
