IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to unauthenticated remote code execution via Java native deserialization on the PayDir Business Rules Manager RMI SSL endpoint (BrmRMISSLServerSocketFactory.java:95, EP8). An adjacent-network attacker can deliver a crafted serialized payload to achieve arbitrary code execution, exposing all PayDir credentials and enabling manipulation of payment business rules.
