PHP vulnerability analysis and mitigation
Overview
A vulnerability was identified in shannah Xataface up to version 2.x, tracked as CVE-2021-4303. The vulnerability affects the installer component of the application, which is disabled by default (GitHub Commit).
Technical details
The vulnerability is related to an XSS (Cross-Site Scripting) issue in the installer component. The issue specifically involves unsafe evaluation of user input in the installer form, where eval() was being used to process results instead of safer JSON parsing methods (GitHub Commit).
Impact
The impact of this vulnerability is considered low threat since the installer component is disabled by default and requires valid MySQL database credentials to access. The vulnerability could only be exploited by users who already have authenticated access to the system (GitHub Commit).
Mitigation and workarounds
The vulnerability has been fixed by replacing the unsafe eval() call with JSON.parse() and changing innerHTML to innerText for safer output handling. Users should upgrade to version 3.0.0 or later which includes this security fix (GitHub Release).
