#VU26401 XML External Entity injection in RapidDeploy - CVE-2020-2171

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input. A remote authenticated attacker able to control the input files for the "RapidDeploy deployment package build" build or post-build step can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
