Weaver E-office < 10.0_20221201 Unauthenticated Arbitrary File Read via XmlRpcServlet

Weaver (Fanwei) E-office versions prior to 10.0_20221201 contain an unauthenticated arbitrary file upload vulnerability in the OfficeServer.php endpoint that allows remote attackers to upload malicious files by sending multipart POST requests with arbitrary filenames and disguised content types. Attackers can upload PHP webshells to the Document directory and execute them via HTTP GET requests to achieve remote code execution as the web server user. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-10-10 (UTC).

Fanwei E-Office Unauthenticated File Upload

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. Successful exploitation could enable remote code execution on the affected server, leading to complete compromise of the web application and potentially the underlying system. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.
