Assigner: VulnCheck

Description
UnForm Server versions < 10.1.15 contain an unauthenticated arbitrary file read and SMB coercion vulnerability in the Doc Flow feature’s 'arc' endpoint. The Doc Flow module uses the 'arc' handler to retrieve and render pages or resources specified by the user-supplied 'pp' parameter, but it does so without enforcing authentication or restricting path inputs. As a result, an unauthenticated remote attacker can supply local filesystem paths to read arbitrary files accessible to the service account. On Windows deployments, providing a UNC path can also coerce the server into initiating outbound SMB authentication, potentially exposing NTLM credentials for offline cracking or relay. This issue may lead to sensitive information disclosure and, in some environments, enable further lateral movement.

CWE ID Description
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.
CWE-918 The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in UnForm Server versions prior to 10.1.15 in the Doc Flow feature's 'arc' endpoint. It allows an unauthenticated remote attacker to read arbitrary files on the server by supplying local filesystem paths through the 'pp' parameter without authentication or path restrictions. Additionally, on Windows systems, the attacker can provide a UNC path that forces the server to initiate outbound SMB authentication, potentially exposing NTLM credentials for offline cracking or relay attacks.


How can this vulnerability impact me? :

The vulnerability can lead to sensitive information disclosure by allowing attackers to read arbitrary files accessible to the service account. On Windows deployments, it can also expose NTLM credentials through SMB coercion, which attackers can use for offline cracking or relay attacks. This may enable further lateral movement within the affected environment, increasing the risk of broader compromise.
