CVE-2022-0557:
PHP vulnerability analysis and mitigation
Overview
OS Command Injection vulnerability (CVE-2022-0557) was discovered in Packagist microweber/microweber prior to version 1.2.11. The vulnerability allowed authenticated users to execute arbitrary code on the system through the file upload functionality (CVE, Huntr).
Technical details
The vulnerability exists in the file upload functionality of the user profile section. An authenticated user could upload a specially crafted image file with PHP code and a PHP7 extension (e.g., .php7). The application failed to properly validate the file extension, allowing the execution of PHP code on the server (Exploit DB).
Impact
The vulnerability allows authenticated attackers to execute arbitrary code on the affected system, potentially leading to complete system compromise. Since this requires authentication, the impact is somewhat limited to users who already have access to the system (Exploit DB).
Mitigation and workarounds
The vulnerability has been patched in version 1.2.11 of Microweber. Users should upgrade to this version or later. The fix involves improved validation of file extensions during the upload process (GitHub).
