CVE-2024-1153 is an SQL Injection vulnerability classified under CWE-89, found in Talya Informatics Travel APPS versions prior to 17.0.68. The vulnerability stems from improper neutralization of special characters in SQL commands, which allows attackers to manipulate backend database queries. This occurs due to incorrectly configured access control security levels, potentially enabling unauthorized access to sensitive data stored in the application's database. The vulnerability can be exploited remotely over the network without requiring authentication or user interaction, increasing its risk profile. The CVSS v3.1 score is 4.6 (medium), with the vector indicating network attack vector (AV:P), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no integrity or availability impact (I:N/A:N). Although no public exploits have been reported, the vulnerability could allow attackers to extract confidential information such as user credentials, travel itineraries, or payment details. The lack of integrity and availability impact means the database contents cannot be altered or deleted through this flaw, but confidentiality breaches alone can have severe consequences. The vulnerability highlights the importance of proper input validation, parameterized queries, and secure access control configurations in web applications handling sensitive data. Talya Informatics has not yet released a patch, so organizations must monitor for updates and apply them promptly once available.

For European organizations, the primary impact of CVE-2024-1153 is the potential unauthorized disclosure of sensitive customer and business data managed by the Travel APPS platform. This could include personally identifiable information (PII), travel plans, payment information, and internal operational data. Such data breaches can lead to regulatory penalties under GDPR, reputational damage, and loss of customer trust. The vulnerability does not allow data modification or service disruption, so operational continuity is less affected. However, attackers exploiting this flaw could gain insights into business operations or customer behavior, which could be leveraged for further attacks or fraud. Organizations in the travel, tourism, and government sectors using Talya Informatics products are particularly at risk. The medium severity score reflects a moderate risk level but should not be underestimated given the sensitivity of travel-related data. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially as attackers often develop exploits after public disclosure. European entities must prioritize detection and prevention to avoid data breaches and comply with stringent data protection laws.

1. Monitor Talya Informatics communications for official patches and apply updates to Travel APPS promptly once available. 2. In the interim, restrict network access to the Travel APPS backend to trusted IP ranges and implement network-level segmentation to limit exposure. 3. Conduct a thorough review of access control configurations within the application to ensure least privilege principles are enforced and no overly permissive settings exist. 4. Implement web application firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the Travel APPS endpoints. 5. Employ input validation and sanitization techniques on all user-supplied data, using parameterized queries or prepared statements to prevent injection. 6. Perform security testing, including automated scanning and manual penetration testing focused on SQL injection vectors, to identify and remediate similar vulnerabilities. 7. Enhance monitoring and logging to detect suspicious database query patterns or unauthorized data access attempts. 8. Train development and security teams on secure coding practices related to database interactions and access control management. 9. Prepare incident response plans specifically addressing data breach scenarios involving travel application data. 10. Coordinate with Talya Informatics support for guidance and vulnerability status updates.
