Remote code execution via unrestricted PHP upload
Published May 11, 2023 · Updated Jan 24, 2025
Unrestricted file upload in Weaver Network Technology e-office 9.5 allows remote attackers to execute PHP code through a multipart request. The /inc/jquery/uploadify/uploadify.php handler accepts attacker-controlled Filedata content and a PHP filename, stores the file in a random web-accessible directory, and returns that directory without blocking the executable type. The published request contains no authentication, and successful exploitation runs attacker-supplied PHP in the web server context.
