# CVE-2025-34350: UnForm Server \< 10.1.15 Doc Flow Unauthenticated File Read

- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 10.1.15

## Affected

- Synergetic Data Systems, Inc. UnForm Server: fixed in 10.1.15

## 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.

## What to do

- Check your stack: if you ship or depend on Synergetic Data Systems, Inc. UnForm Server, upgrade to a fixed version (10.1.15) per the references below.
