CVE-2013-4793
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 · uneditedThe update function in umbraco.webservices/templates/templateService.cs in the TemplateService component in Umbraco CMS before 6.0.4 does not require authentication, which allows remote attackers to execute arbitrary ASP.NET code via a crafted SOAP request.
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 confidenceThe TemplateService component in Umbraco CMS versions before 6.0.4 contains an authentication bypass vulnerability in its update function (templateService.cs). The SOAP web service endpoint does not require authentication, allowing remote attackers to send crafted SOAP requests that result in arbitrary ASP.NET 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 Umbraco CMS is installedLook for Umbraco installation files such as the /bin/Umbraco.dll assembly, web.config file in the root, or the /umbraco/ directory path. Check for 'Umbraco' references in the application.Affected if Umbraco CMS is present in the environment
-
Determine the installed Umbraco CMS versionCheck the assembly version of Umbraco.dll in the /bin folder, or look for the version in the /umbraco/Version.txt file, or query the /umbraco/Api/ContentApi/GetVersion endpoint if accessible.Affected if The version is 6.0.3 or lower (any version up to and including 6.0.3)
-
Check if SOAP web services are enabledExamine the web.config file for the presence of the UmbracoWebServicesHttpModule in the <system.webServer><modules> section, and look for SOAP service definitions in the <system.webServices> section.Affected if The SOAP web services module is registered and enabled in web.config
-
Verify the TemplateService endpoint is accessibleAttempt to access the TemplateService SOAP endpoint at /umbraco/webservices/TemplateService.asmx or check if this file exists in the /umbraco/webservices/ directory.Affected if The TemplateService.asmx file exists and is reachable from the network
A user is affected if they are running Umbraco CMS version 6.0.3 or lower with the SOAP web service endpoint (TemplateService) enabled and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Umbraco CMS to version 6.0.4 or later. As a temporary workaround, disable the umbraco.webservices templates endpoint or block external access to SOAP services if not required.
