An unsafe reflection vulnerability in Kentico Xperience allows an unauthenticated attacker to kill the current process, leading to a Denial-of-Service condition. This issue affects Xperience: through 13.0.180.

An authenticated remote code execution in Kentico Xperience allows authenticated users Staging Sync Server to upload arbitrary data to path relative locations. This results in path traversal and arbitrary file upload, including content that can be executed server side leading to remote code execution.This issue affects Kentico Xperience through 13.0.178.

The Kentico Xperience application does not fully validate or filter files uploaded via the multiple-file upload functionality, which allows for stored XSS.This issue affects Kentico Xperience through 13.0.178.

In Kentico before 13.0.66, attackers can achieve Denial of Service via a crafted request to the GetResource handler.

Kentico CMS before 13.0.66 has an Insecure Direct Object Reference vulnerability. It allows an attacker with user management rights (default is Administrator) to export the user options of any user, even ones with higher privileges (like Global Administrators) than the current user. The exported XML contains every option of the exported user (even the hashed password).

Kentico Xperience 13.0.44 allows XSS via an XML document to the Media Libraries subsystem.

The Blog module in Kentico CMS 5.5 R2 build 5.5.3996 allows SQL injection via the tagname parameter.

Cross Site Scripting (XSS) vulnerability in Kentico before 12.0.75.

Kentico before 12.0.50 allows file uploads in which the Content-Type header is inconsistent with the file extension, leading to 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

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

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 v10.0.42 allows Global Administrators to read the cleartext SMTP Password by navigating to the SMTP configuration page. NOTE: the vendor considers this a best-practice violation but not a vulnerability. The vendor plans to fix it at a future time

NOTE: the vendor has responded that there is intended functionality for authorized users to edit and update ascx code layout

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 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

Open redirect vulnerability in CMSPages/GetDocLink.ashx in Kentico CMS 8.2 through 8.2.41 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the link parameter.
