CVE-2025-59710
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in Biztalk360 before 11.5. Because of incorrect access control, any user is able to request the loading a DLL file. During the loading, a method is called. An attacker can craft a malicious DLL, upload it to the server, and use it to achieve remote code execution on the server.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceBiztalk360 before version 11.5 contains an insecure direct object reference or broken access control vulnerability that allows any user to trigger DLL file loading. Because proper authorization checks are missing, an attacker can upload a crafted malicious DLL that gets loaded by the application, leading to arbitrary method execution and remote code execution on the server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Biztalk360 is installedCheck for Biztalk360 web application in your IIS sites or application pool, or look for the Biztalk360 installation directory on the serverAffected if Biztalk360 is present in the environment
-
Determine the installed Biztalk360 versionLocate the Biztalk360 version information - typically found in the application binaries, configuration files, or the About page within the Biztalk360 web interfaceAffected if The installed version is lower than 11.6.3963.2611
-
Check if DLL loading functionality is accessibleVerify whether the DLL loading/upload feature is exposed in the Biztalk360 web interface - this is typically found in the monitoring or configuration sectionsAffected if The DLL loading feature is enabled and accessible to users
-
Verify access control on the DLL loading endpointInspect the application permissions or test whether unauthenticated or low-privilege users can access the DLL loading functionalityAffected if Users without administrative privileges can access or trigger the DLL loading feature
The environment is affected if Biztalk360 is installed with a version lower than 11.6.3963.2611 and the DLL loading feature is exposed to users without proper access control restrictions.

dbcve · scoped11.6.3963.2611
Upgrade to Biztalk360 version 11.5 or later. As a compensating control, restrict file upload permissions to only trusted administrators and implement application-level DLL allow-listing or integrity verification before loading.
Biztalk360 version 11.6.3963.2611 or later
- 1. Back up the Biztalk360 database and configuration files before upgrading.
- 2. Download Biztalk360 version 11.6.3963.2611 or later from the official vendor portal.
- 3. Stop the Biztalk360 services to ensure a clean upgrade process.
- 4. Run the installer for version 11.6.3963.2611 following the vendor's upgrade documentation.
- 5. After installation, verify that the services start successfully.
- 6. Validate that the DLL upload vulnerability is patched by confirming only authorized users can upload files and that arbitrary DLL loading is no longer possible.
- 7. Test core Biztalk360 functionality to ensure the upgrade did not break existing workflows.
