Detailsinfo

A vulnerability was found in Synergetic Data Systems UnForm Server up to 10.1.14 and classified as critical. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality. CVE summarizes:

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.

The weakness was shared by Victor Morales. The advisory is available at unform.com. This vulnerability is handled as CVE-2025-34350 since 04/15/2025. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 10.1.15 eliminates this vulnerability.
