CVE-2024-41345 is a Cross-Site Scripting (XSS) vulnerability identified in the openflights project, specifically in the php/trip.php component. The vulnerability arises due to insufficient sanitization or encoding of user-supplied input before it is reflected in the web page output, allowing an attacker to inject arbitrary JavaScript code. When a victim user accesses the affected page with a crafted URL or input, the malicious script executes in their browser context, potentially stealing session cookies, performing actions on behalf of the user, or defacing the web interface. The vulnerability has a CVSS 3.1 base score of 6.1, indicating medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact affects confidentiality and integrity partially (C:L/I:L) but not availability (A:N). No patches or exploits are currently publicly available, but the vulnerability is published and should be addressed. The CWE-79 classification confirms this is a classic reflected XSS issue. The lack of affected version details suggests the vulnerability may be in recent or specific commits, requiring users to audit their deployments carefully. Since openflights is an open-source flight data and trip planning tool, organizations using it for travel, aviation, or logistics may be exposed.

For European organizations, the primary impact of CVE-2024-41345 lies in the potential compromise of user sessions and data confidentiality when users interact with the vulnerable openflights php/trip.php page. Attackers could exploit this vulnerability to execute malicious scripts that steal authentication tokens or manipulate user data, leading to unauthorized access or data integrity issues. While availability is not impacted, the breach of confidentiality and integrity could undermine trust in affected services, especially in sectors such as aviation, travel agencies, and logistics companies that rely on openflights for trip planning or flight data management. Additionally, regulatory compliance under GDPR mandates protection of personal data, and exploitation of this vulnerability could lead to data breaches with legal and financial consequences. The lack of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits. Organizations with public-facing instances of openflights are at higher risk, particularly if users are not trained to recognize phishing or malicious links that could trigger the XSS.

To mitigate CVE-2024-41345, organizations should first identify all instances of openflights deployments and verify if they include the vulnerable php/trip.php component. Since no official patch links are currently available, immediate mitigation involves implementing strict input validation and output encoding on all user-supplied data in trip.php to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of potential XSS payloads. Additionally, enable HttpOnly and Secure flags on cookies to protect session tokens from theft via script access. Conduct security code reviews focusing on input handling in trip.php and related modules. Educate users about the risks of clicking suspicious links and consider deploying Web Application Firewalls (WAFs) with rules to detect and block reflected XSS attempts targeting the vulnerable endpoint. Monitor logs for unusual activity or error patterns indicative of attempted exploitation. Finally, stay updated with openflights project communications for official patches or updates addressing this vulnerability.
