Vulnerabilities

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.

UiPath Assistant 21.4.4 will load and execute attacker controlled data from the file path supplied to the --dev-widget argument of the URI handler for uipath-assistant://. This allows an attacker to execute code on a victim's machine or capture NTLM credentials by supplying a networked or WebDAV file path.

UiPath Orchestrator before 2018.3.4 allows CSV Injection, related to the Audit export, Robot log export, and Transaction log export features.

UiPath Orchestrator through 2018.2.4 allows any authenticated user to change the information of arbitrary users (even administrators) leading to privilege escalation and remote code execution.
