PHP vulnerability analysis and mitigation
Overview
In PageKit v1.0.18, a vulnerability was discovered that allows users to upload SVG files containing malicious scripts through the CMS file upload functionality. The vulnerability was assigned CVE-2021-32245 and was disclosed on June 16, 2021 (NVD, GitHub Issue).
Technical details
The vulnerability exists in the file upload functionality of PageKit CMS version 1.0.18. When a user uploads an SVG file, the system does not properly strip or filter the file content, allowing malicious scripts within the SVG to remain intact. The vulnerability was confirmed in an environment running nginx 1.15.11, MySQL 5.7.26, and PHP 7.3.4 (GitHub Issue).
Impact
When exploited, this vulnerability allows attackers to execute arbitrary JavaScript code in victims' browsers when the malicious SVG file is accessed. The attack can be triggered when users click on links pointing to the uploaded SVG file (e.g., '/storage/exp.svg'), resulting in a stored Cross-Site Scripting (XSS) attack (GitHub Issue).
