CVE-2021-44043
There is a persistent XSS vulnerability in the file-upload functionality for uploading icons when attempting to create new Apps.
Does this matter?
Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in UiPath App Studio 21.4.4. There is a persistent XSS vulnerability in the file-upload functionality for uploading icons when attempting to create new Apps. An attacker with minimal privileges in the application can build their own App and upload a malicious file containing an XSS payload, by uploading an arbitrary file and modifying the MIME type in a subsequent HTTP request. This then allows the file to be stored and retrieved from the server by other users in the same organization.
