CVE-2024-41348 is a Cross-Site Scripting (XSS) vulnerability identified in the openflights project, specifically in the php/alsearch.php file. The vulnerability arises from improper sanitization of user-supplied input, which is then reflected in the web application's output without adequate encoding or filtering. This flaw allows attackers to inject malicious JavaScript code that executes in the context of a victim’s browser when they visit a crafted URL or interact with manipulated input fields. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. According to the CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), the attack can be launched remotely over the network without authentication, requires low attack complexity, and necessitates user interaction (such as clicking a link). The scope is changed (S:C), indicating the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting other parts of the application or user sessions. The impact includes limited confidentiality and integrity loss, such as theft of session cookies, defacement, or redirection to malicious sites, but does not affect system availability. No patches or fixes have been published yet, and no active exploitation has been reported, suggesting the vulnerability is newly disclosed. Organizations using openflights or similar web components should prioritize remediation to prevent exploitation.

For European organizations, this XSS vulnerability could lead to unauthorized disclosure of sensitive information such as session tokens or user credentials, enabling attackers to impersonate users or escalate privileges within the application. It could also facilitate phishing attacks by injecting malicious content into trusted web pages, damaging organizational reputation and user trust. Since openflights is an open-source project often used in aviation, travel, or logistics-related applications, organizations in these sectors may face increased risk. The vulnerability could be exploited to target employees or customers, potentially leading to broader network compromise if credentials are reused. Although no availability impact is expected, the integrity and confidentiality risks could disrupt business operations and compliance with data protection regulations such as GDPR. The lack of a patch increases the urgency for temporary mitigations and monitoring.

European organizations should implement strict input validation and output encoding on all user-supplied data, especially in the php/alsearch.php component or any similar search functionalities. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce XSS impact. Use web application firewalls (WAFs) with updated signatures to detect and block malicious payloads targeting this vulnerability. Conduct thorough code reviews and penetration testing focusing on injection points in the application. Isolate vulnerable components and restrict access where possible until a patch is available. Educate users about the risks of clicking suspicious links and implement multi-factor authentication to reduce the impact of stolen credentials. Monitor logs for unusual activity indicative of XSS exploitation attempts. Engage with the openflights community or maintainers to track patch releases and apply updates promptly once available.
