Exploitation evidence was first observed by the Shadowserver Foundation on 2022-10-10 (UTC).
Unrestricted File Upload
Fanwei E-Office <=9.4 Unauth File Upload (UploadFile.php) RCE

An unauthenticated file upload vulnerability exists in the Fanwei E-Office <= v9.4 web management interface. The vulnerability affects the /general/index/UploadFile.php endpoint, which improperly validates uploaded files when invoked with certain parameters (uploadType=eoffice_logo or uploadType=theme). An attacker can exploit this flaw by sending a crafted HTTP POST request to upload arbitrary files without requiring authentication.
