Kentico Xperience

Kentico Xperience <= 13.0.178 Staging Sync Server None Password Type Authentication Bypass

An issue was discovered in Kentico 12.0.x before 12.0.15, 11.0.x before 11.0.48, 10.0.x before 10.0.52, and 9.x versions. Due to a failure to validate security headers, it was possible for a specially crafted request to the staging service to bypass the initial authentication and proceed to deserialize user-controlled .NET object input. This deserialization then led to unauthenticated remote code execution on the server where the Kentico instance was hosted.

Kentico 9.0 before 9.0.51 and 10.0 before 10.0.48 allows remote attackers to obtain Global Administrator access by visiting CMSInstall/install.aspx and then navigating to the CMS Administration Dashboard.

Kentico Xperience before 13.0.178 has a specific set of allowed ContentUploader file extensions for unauthenticated uploads; however, because .zip is processed through TryZipProviderSafe, there is additional functionality to create files with other extensions. NOTE: this is a separate issue not necessarily related to SVG or XSS.

Kentico 11 through 12 lets attackers upload and explore files without authentication via the cmsmodules/medialibrary/formcontrols/liveselectors/insertimageormedia/tabs_media.aspx URI. NOTE: The vendor disputes the report because the researcher did not configure the media library permissions correctly. The vendor states that by default all users can read/modify/upload files, and it’s up to the administrator to decide who should have access to the media library and set the permissions accordingly. See the vendor documentation in the references for more information

Arbitrary code execution vulnerability in Kentico 9 through 11 allows remote authenticated users to execute arbitrary operating system commands in a dynamic .NET code evaluation context via C# code in a "Pages -> Edit -> Template -> Edit template properties -> Layout" box. NOTE: the vendor has responded that there is intended functionality for authorized users to edit and update ascx code layout

Kentico CMS before 11.0.45 allows unrestricted upload of a file with a dangerous type.

Kentico 9.0 through 11.0 has a stack-based buffer overflow via the SqlName, SqlPswd, Database, UserName, or Password field in a SilentInstall XML document. NOTE: the vendor disputes this issue because neither a buffer overflow nor a crash can be reproduced; also, reading XML documents is implemented exclusively with managed code within the Microsoft .NET Framework
