Kentico Xperience does not fully validate or filter files uploaded through its multiple-file upload functionality, which leaves the flaw in that upload feature of the product. An attacker who can reach the application over the network can plant a stored cross-site scripting payload, and it executes when a user interacts with the affected content, requiring no authentication but depending on that user interaction.
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.
