Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires timely flaw remediation by applying the Laravel 11.36.0 patch that fixes improper encoding of request parameters on debug error pages.

CM-6 Configuration Settings good match

prevent

Enforces secure configuration settings to disable debug mode in production, preventing generation of vulnerable error pages reflecting unencoded request parameters.

SI-15 Information Output Filtering good match

prevent

Mandates filtering and encoding of information outputs like request parameters on error pages to block reflected XSS payloads.

MITRE ATT&CK Enterprise TechniquesAI

T1204.001 Malicious Link Execution

An adversary may rely upon a user clicking a malicious link in order to gain execution.

T1185 Browser Session Hijacking Collection

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.

Why these techniques?

Reflected XSS via crafted link enables user execution of malicious link (T1204.001) and directly facilitates browser session hijacking through arbitrary script execution (T1185).

NVD Description

The Laravel framework versions between 11.9.0 and 11.35.1 are susceptible to reflected cross-site scripting due to an improper encoding of request parameters in the debug-mode error page.

Deeper analysisAI

CVE-2024-13918 is a reflected cross-site scripting vulnerability (CWE-79) affecting the Laravel framework in versions 11.9.0 through 11.35.1. The issue arises from improper encoding of request parameters when displayed on the debug-mode error page, enabling malicious scripts to be reflected back to users. It carries a CVSS v3.1 base score of 8.0 (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N) and was published on 2025-03-10.

Attackers can exploit this over the network without requiring privileges, though it demands high complexity and user interaction, such as clicking a crafted link. By inducing an error in debug mode, an attacker can inject and reflect XSS payloads via request parameters, achieving high impacts on confidentiality and integrity with a changed scope, potentially allowing session hijacking or arbitrary script execution in the victim's browser.

Patches are available in Laravel framework version 11.36.0, addressing the flaw through pull request #53869 on GitHub. Further mitigation details appear in the SBA Research advisory (SBA-ADV-20241209-01) and the oss-security mailing list discussion from March 10, 2025.
