CVE-2025-11397 identifies a SQL injection vulnerability in the SourceCodester Hotel and Lodge Management System version 1.0. The vulnerability exists in an unspecified function within the /login.php file, where the email parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw can be exploited remotely without authentication or user interaction, enabling attackers to manipulate backend database queries. Potential consequences include unauthorized retrieval, modification, or deletion of sensitive data stored in the database, such as user credentials, booking information, or payment details. The vulnerability has a CVSS 4.0 score of 6.9, reflecting a medium severity level due to its network attack vector, lack of required privileges, and no user interaction needed, but with limited impact on confidentiality, integrity, and availability. Although no confirmed exploits are currently active in the wild, the public release of exploit code increases the likelihood of attacks. The lack of available patches at the time of disclosure necessitates immediate interim mitigations. This vulnerability poses a significant risk to organizations relying on this software for managing hotel and lodge operations, especially those handling sensitive customer data.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive customer and business data, including personal identification, booking records, and payment information. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers might alter or delete critical operational data, disrupting hotel management services and causing availability issues. The hospitality sector in Europe is a high-value target due to its economic importance and the volume of personal data processed. Organizations using the affected software without proper mitigations are at increased risk of targeted attacks, potentially impacting customer trust and operational continuity.

1. Immediately audit all instances of SourceCodester Hotel and Lodge Management System version 1.0 to identify affected deployments. 2. Implement strict input validation and sanitization on the email parameter in /login.php, ensuring that only valid email formats are accepted. 3. Refactor database queries to use parameterized statements or prepared queries to eliminate SQL injection vectors. 4. Monitor database logs and application logs for unusual query patterns or repeated failed login attempts indicative of exploitation attempts. 5. Restrict database user permissions to the minimum necessary to limit the impact of any injection. 6. Deploy web application firewalls (WAFs) with rules specifically targeting SQL injection patterns on the affected endpoint. 7. Engage with the vendor or community to obtain or develop official patches and apply them promptly once available. 8. Conduct security awareness training for IT staff to recognize and respond to exploitation attempts. 9. Regularly back up critical data and verify restoration procedures to mitigate potential data loss from attacks.
