GHSA-fgrx-4637-fcf5:
PHP vulnerability analysis and mitigation
Overview
The vulnerability (GHSA-fgrx-4637-fcf5) affects the Crypt encryption in FuelPHP's core component versions prior to 1.8.1. With the right knowledge, code, and GPU calculation power, the Crypt encryption could be broken in minutes, posing a significant security risk (FuelPHP Advisory).
Technical details
The vulnerability exists in the core encryption mechanism of FuelPHP, where the implemented cryptographic method was found to be susceptible to brute force attacks when attackers have access to sufficient GPU computation power. The issue affects all released versions starting from 1.0 up to version 1.8.0 (GitHub Advisory).
Impact
The vulnerability allows malicious actors with the right tools and knowledge to break the encryption in minutes, potentially exposing sensitive encrypted data to unauthorized access (FuelPHP Advisory).
Mitigation and workarounds
The issue was addressed in release v1.8.1. Users can modify earlier versions by implementing the changes from the provided fix and installing the 'paragonie/sodium-compat' composer package if running on PHP < 7.2. The fix involves switching to Sodium encryption, which provides stronger cryptographic security (FuelPHP Advisory, Core Commit).
