Reflected Cross-Site Scripting Vulnerability in Laravel Framework

CVE-2024-13918

What is CVE-2024-13918?

CVE-2024-13918 is a reflected cross-site scripting (XSS) vulnerability found in the Laravel Framework, a popular PHP framework widely used for web application development. This vulnerability affects Laravel Framework versions from 11.9.0 to 11.35.1, primarily due to improper encoding of request parameters in debug-mode error pages. If exploited, this vulnerability can allow attackers to inject malicious scripts into web pages seen by users, potentially leading to unauthorized actions or information theft, which poses a significant security risk for organizations relying on Laravel for their applications.

Technical Details

The vulnerability arises specifically from how the Laravel Framework handles request parameters when displaying error messages in debug mode. In this state, the application does not sufficiently encode these parameters, making it possible for adversaries to inject and execute JavaScript code in a user's browser who views the debug error page. The improper handling is limited to debug mode and affects only the specific versions mentioned, requiring organizations to evaluate their usage and configurations for potential vulnerabilities.

Potential impact of CVE-2024-13918

1. Unauthorized Script Execution: An attacker can exploit this vulnerability to execute arbitrary scripts in the context of a user's session. This could lead to actions such as session hijacking, where the attacker could impersonate the user by stealing session cookies.

2. Data Exposure: If attackers successfully inject scripts, they could potentially capture sensitive user data entered into forms on the website, leading to significant privacy violations and data breaches.

3. Reputation Damage: Organizations affected by this vulnerability might face reputational harm, particularly if user data is misused or if end-users experience harmful impacts due to exploitations, leading to loss of trust and potential revenue losses.
