PHP vulnerability analysis and mitigation

Overview

CVE-2024-52301 is a critical vulnerability identified in Laravel, a widely used PHP web application framework. The vulnerability was discovered and disclosed on November 12, 2024, affecting multiple versions of Laravel including versions below 6.20.45, 7.0.0-7.30.7, 8.0.0-8.83.28, 9.0.0-9.52.17, 10.0.0-10.48.23, and 11.0.0-11.31.0. The issue received a CVSS v4.0 base score of 8.7 (High) (GitHub Advisory).

Technical details

The vulnerability stems from improper input validation related to Laravel's environment configuration handling. Specifically, when the PHP directive registerargcargv is set to 'on', attackers can manipulate the framework's environment through specially crafted URL query strings. This allows unauthorized modification of the environment used by the framework when processing requests (NVD, Security Online).

Impact

The vulnerability could expose Laravel-based applications to unauthorized access, data tampering, and privilege escalation. Given Laravel's widespread adoption across industries, this vulnerability poses a significant risk to organizations running affected versions in production environments (GBHackers).

Mitigation and workarounds

Laravel has released patches across all affected versions with the following fixed versions: 6.20.45, 7.30.7, 8.83.28, 9.52.17, 10.48.23, and 11.31.0. The patch ensures that Laravel ignores argv values for environment detection on non-CLI SAPIs (Server Application Programming Interfaces). Organizations are strongly advised to upgrade to these patched versions immediately (GitHub Advisory, Debian Advisory).
