Authentication bypass allows an attacker to control administrative objects.This issue affects Xperience through 13.0.172.

An authentication bypass vulnerability in Kentico Xperience allows authentication bypass via the Staging Sync Server component password handling for the server defined None type. Authentication bypass allows an attacker to control administrative objects.This issue affects Xperience through 13.0.178.

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 contains a failure to validate security headers. This deserialization can led to unauthenticated remote code execution.

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.

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

DISPUTED Kentico 11 through 12 lets attackers upload and explore files without authentication via the cmsmodules/medialibrary/formcontrols/liveselectors/insertimageormedia/tabsmedia.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.

An unrestricted file upload vulnerability in Kentico Xperience allows authenticated users with 'Read data' permissions to upload arbitrary file types via MVC form file uploader components. Attackers can manipulate file names and upload potentially malicious files to the system, enabling unauthorized file uploads.

A SQL injection vulnerability in Kentico Xperience allows authenticated editors to inject malicious SQL queries via online marketing macro method parameters. This enables unauthorized database access and potential data manipulation by exploiting macro method input validation weaknesses.

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

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.

A denial of service vulnerability in Kentico Xperience allows attackers to launch DoS attacks via specially crafted requests to the GetResource handler. Improper input validation enables remote attackers to potentially disrupt service availability through maliciously constructed requests.

An access control bypass vulnerability in Kentico Xperience allows administrators to modify global administrator user privileges via unauthorized requests. Attackers could potentially compromise global administrator accounts and invalidate security-sensitive macros by manipulating user privilege levels.

DISPUTED 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.

Kentico Xperience 13 is vulnerable to a stored cross-site scripting attack via a form component, allowing an attacker to hijack a victim user’s session and perform actions in their security context.

A cryptography vulnerability in Kentico Xperience allows attackers to potentially manipulate URL hash values through existing hashing mechanisms. The hotfix introduces an additional security layer to prevent hash value reuse and potential exploitation.

An information disclosure vulnerability in Kentico Xperience allows attackers to view sensitive stack trace details via Portal Engine form control error messages. Detailed error messages can expose internal system information and potentially reveal implementation details to unauthorized users.

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

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.

DISPUTED 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.

DISPUTED 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 10 before 10.0.50 and 11 before 11.0.3 has SQL injection in the administration interface.

A cookie security configuration vulnerability in Kentico Xperience allows attackers to bypass SSL requirements when setting administration cookies via web.config. The vulnerability affects .NET Framework projects by incorrectly handling the 'requireSSL' attribute, potentially compromising session security and authentication state.

An information disclosure vulnerability in Kentico Xperience allows public users to access sensitive administration interface hostname details during authentication. Attackers can retrieve confidential hostname configuration information through a public endpoint, potentially exposing internal network details.

A CRLF injection vulnerability in Kentico Xperience allows attackers to manipulate URL query string redirects via improper encoding in the routing engine. This could enable header injection and potentially facilitate further web application attacks.

The Kentico Xperience CMS version 13.0 – 13.0.43 is vulnerable to a persistent Cross-Site Scripting (XSS) vulnerability (also known as Stored or Second-Order XSS). Persistent XSS vulnerabilities occur when the application stores and retrieves client supplied data without proper handling of dangerous content. This type of XSS vulnerability is exploited by submitting malicious script content to the application which is then retrieved and executed by other application users. The attacker could exploit this to conduct a range of attacks against users of the affected application such as session hijacking, account take over and accessing sensitive data.

Kentico Xperience before 13.0.181 allows authenticated users to distribute malicious content (for stored XSS) via certain interactions with the media library file upload feature.

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.

A reflected cross-site scripting vulnerability in Kentico Xperience allows attackers to inject malicious scripts via administration input fields in the Rich text editor component. Attackers can exploit this vulnerability to execute arbitrary scripts in users' browsers.

A reflected cross-site scripting vulnerability in Kentico Xperience allows attackers to inject malicious scripts via the Pages dashboard widget configuration dialog. Attackers can exploit this vulnerability to execute malicious scripts in administrative users' browsers.
