In short

IBM QRadar SIEM versions 7.3 and 7.4 have a flaw that allows attackers to run malicious commands on the server by sending specially crafted data. This happens because the software unsafely processes Java objects without proper validation.

Technical detail

The vulnerability exists in the Java deserialization function of QRadar SIEM 7.3/7.4, where user-supplied serialized objects are processed without adequate validation. An unauthenticated remote attacker can send a malicious serialized Java object to trigger arbitrary command execution on the affected system.
