Description

Weaver (Fanwei) E-cology 9.5 versions prior to 10.52 contain an arbitrary file read vulnerability in the XmlRpcServlet interface at the XML-RPC endpoint that allows unauthenticated remote attackers to read arbitrary files by supplying file paths to the WorkflowService.getAttachment and WorkflowService.LoadTemplateProp methods. Attackers can exploit these methods without authentication to retrieve sensitive files including system configuration files and database credentials from the server. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-12-14 (UTC).
