CVE-2019-11875 – Blue Prism Robotic Process Automation (RPA) Privilege Escalation

https://notcve.org/view.php?id=CVE-2019-11875

In AutomateAppCore.dll in Blue Prism Robotic Process Automation 6.4.0.8445, a vulnerability in access control can be exploited to escalate privileges. The vulnerability allows for abusing the application for fraud or unauthorized access to certain information. The attack requires a valid user account to connect to the Blue Prism server, but the roles associated to this account are not required to have any permissions. First of all, the application files are modified to grant full permissions on the client side. In a test environment (or his own instance of the software) an attacker is able to grant himself full privileges also on the server side. • http://packetstormsecurity.com/files/153007/Blue-Prism-Robotic-Process-Automation-RPA-Privilege-Escalation.html https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-002.txt • CWE-669: Incorrect Resource Transfer Between Spheres CWE-862: Missing Authorization •
