CyberRota Analysis
AI-GeneratedThe CodeIgniter framework prior to version 4.7.4 is vulnerable due to inadequate validation of client-supplied filenames during file uploads, specifically when using the is_image and mime_in rules. This flaw allows remote attackers to upload executable files, potentially leading to remote code execution if these files are stored in a web-accessible directory. Developers using affected versions should prioritize upgrading to 4.7.4 to mitigate the risk of exploitation.

Original NVD Description
CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, the is_image and mime_in upload validation rules do not independently enforce a safe client filename extension, allowing a remote attacker to upload executable content when an application preserves the client filename and stores uploads in a web-accessible script-enabled directory. Applications are impacted when they validate uploads using is_image or mime_in without an independent safe extension check (such as ext_in on patched versions), save uploaded files using the client-supplied filename, and place uploads in a web-accessible directory where PHP files can execute. This issue is fixed in version 4.7.4.
