CVE-2025-8993 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Tour and Travel Management System. The vulnerability exists in the /admin/expense_report.php file, specifically through the manipulation of the 'from_date' parameter. An attacker can remotely exploit this flaw without requiring any authentication or user interaction. By injecting malicious SQL code into the 'from_date' argument, an attacker could manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of database operations. The vulnerability has a CVSS 4.0 base score of 6.9, classified as medium severity, reflecting its network attack vector, low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant risks depending on the database content and system usage. No official patches or fixes have been disclosed yet, and while no known exploits are currently in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts.

For European organizations using the itsourcecode Online Tour and Travel Management System version 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of sensitive business data, including financial records and operational reports managed through the expense_report.php module. Exploitation could lead to unauthorized data disclosure, data tampering, or denial of service conditions affecting the availability of the system. Given the nature of the travel and tour industry, compromised data could include customer information, booking details, and financial transactions, potentially leading to reputational damage, regulatory non-compliance (e.g., GDPR violations), and financial losses. The remote and unauthenticated nature of the attack vector increases the threat level, especially for organizations with internet-facing administrative interfaces. The medium severity rating suggests that while the vulnerability is serious, exploitation requires some level of technical skill and may not lead to full system compromise without additional vulnerabilities.

European organizations should immediately audit their use of the itsourcecode Online Tour and Travel Management System to identify if version 1.0 is deployed, especially in internet-facing environments. As no official patches are currently available, organizations should implement the following specific mitigations: 1) Restrict access to the /admin/expense_report.php endpoint using network-level controls such as IP whitelisting or VPN access to limit exposure to trusted personnel only. 2) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'from_date' parameter. 3) Conduct code reviews and apply input validation and parameterized queries or prepared statements to sanitize user inputs if source code access and modification are possible. 4) Monitor logs for unusual database query patterns or repeated failed attempts to exploit the 'from_date' parameter. 5) Prepare incident response plans to quickly address any detected exploitation attempts. 6) Engage with the vendor or community to obtain or develop patches and plan for timely updates once available.
