CVE-2024-13918
CVE-2024-13918: Laravel framework cross-site scripting vulnerability! Versions 11.9.0 to 11.35.1 are vulnerable to reflected XSS due to improper encoding of request parameters in the debug error page. The Laravel framework debug mode exposes a weakness where request parameters aren't properly encoded, leading to potential script injection. While CVSS rates this as 6.1, SOCRadar's Vulnerability Risk Score (SVRS) is 76, indicating a high risk demanding attention. This vulnerability could allow attackers to execute malicious scripts in users' browsers, potentially leading to session hijacking or data theft. Act quickly to mitigate this threat in your web applications by updating to a patched version.
Description
CVE-2024-13918 is a reflected cross-site scripting (XSS) vulnerability affecting Laravel framework versions 11.9.0 through 11.35.1. The vulnerability stems from improper encoding of request parameters displayed on the debug-mode error page. Although the CVSS score is 8, the SOCRadar Vulnerability Risk Score (SVRS) is 36, suggesting a lower immediate risk compared to vulnerabilities with scores above 80. However, the tag "In The Wild" indicates that this vulnerability is actively exploited by hackers, increasing its importance.
Key Insights
- Reflected XSS: The vulnerability is a reflected XSS, meaning malicious scripts are injected through request parameters. When the application reflects these parameters (specifically on the debug page when an error occurs) without proper encoding, the script executes in the victim's browser.
- Exploit Status: Active exploits are already in use, given the "In The Wild" tag, increasing the urgency of patching this vulnerability, regardless of the relatively low SVRS score.
- Debug Mode Dependency: The vulnerability's exploitation is primarily relevant when the application is in debug mode. While debug mode is typically disabled in production environments, its presence (or inadvertent activation) creates a potential attack vector.
- Affected Versions: Specifically, Laravel versions between 11.9.0 and 11.35.1 are vulnerable. Therefore, knowing the current version of Laravel running within your environment is critical for assessment.
Mitigation Strategies
- Upgrade Laravel: The most effective mitigation is to upgrade to a version of Laravel that is not susceptible to CVE-2024-13918. Check for updates in the Laravel documentation for which version is the fix.
- Disable Debug Mode: Ensure that debug mode is disabled in all production environments. This drastically reduces the attack surface, as the vulnerability is exposed via the debug error page.
- Input Validation and Encoding: Implement robust input validation and output encoding/escaping mechanisms across all application layers. Though specific to debug pages in this instance, general XSS protection is important.
- Web Application Firewall (WAF): Deploy or configure a Web Application Firewall (WAF) to detect and block XSS attacks. A WAF can provide an additional layer of protection even if code-level fixes are not immediately possible.
