Executive Summary

CVE-2023-53737 is a stored cross-site scripting (XSS) vulnerability in Kentico Xperience's Localization application. It allows global administrators to inject malicious scripts that are stored persistently and executed within the administration interface. This happens due to insufficient input sanitization, enabling attackers to run arbitrary scripts affecting multiple parts of the administration interface. [1]

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts within the administration interface of Kentico Xperience. This can compromise administrative operations and security by potentially affecting multiple administrative components, leading to unauthorized actions or data exposure within the administration environment. [1]

Mitigation Strategies

To mitigate this stored cross-site scripting vulnerability in Kentico Xperience, you should update Kentico Xperience to a version later than 13.0.101 where the issue is fixed. Additionally, restrict global administrator privileges to trusted users only, and avoid using the Localization application until the patch is applied.
