Detailsinfo

A vulnerability was found in Weaver Network e-cology up to 10.51. It has been classified as critical. This affects the function WorkflowService.getAttachment/WorkflowService.LoadTemplateProp of the component XmlRpcServlet Interface. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. The summary by CVE is:

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).
