PHP vulnerability analysis and mitigation
Overview
CVE-2024-42485 is a path traversal vulnerability discovered in Filament Excel, a package that enables excel export functionality for Filament admin resources. The vulnerability was disclosed on August 12, 2024, affecting versions from 1.0.0 to 1.1.14 and 2.0.0 to 2.3.3. The issue exists in the export download route /filament-excel/{path} which allowed unauthorized file downloads when the webserver permits ../ in the URL (NVD).
Technical details
The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) with a CVSS v3.1 base score of 7.5 (HIGH). The attack vector is network-accessible (AV:N), requires low attack complexity (AC:L), needs no privileges (PR:N), requires no user interaction (UI:N), has unchanged scope (S:U), and can result in high confidentiality impact (C:H) with no impact on integrity (I:N) or availability (A:N) (NVD).
Impact
The vulnerability allows unauthorized access to files outside the intended directory structure through path traversal techniques. An attacker could potentially access sensitive files on the system when the webserver configuration allows directory traversal using '../' in URLs (GitHub Advisory).
Mitigation and workarounds
The vulnerability has been patched in version 2.3.3 of Filament Excel. Users are strongly advised to upgrade to this version or later to address the security issue. The fix implements signed middleware to prevent unauthorized access to the download endpoint (GitHub Patch).
