The CPU is not configured to provide hardware support for exclusivity of write and execute operations on memory. This allows an attacker to execute data from all of memory.
MITRE ATT&CK techniques associated with this weakness class (mapped via MITRE CAPEC). A vulnerability of this type could let an adversary carry out:
A stage-by-stage walkthrough of the attack, mapped to the real MITRE ATT&CK tactics for this weakness — what the attacker is trying to do, what's at risk (what can be stolen or damaged), and how you defend. Understanding the playbook is how you shut it down.
Run attacker-chosen code or commands on the system.
Application logic and the host runtime — an attacker can execute arbitrary code or commands.
Least-privilege runtime, sandboxing, and safe deserialization/parsing.
This is a defensive, conceptual walkthrough for education — stages reflect MITRE ATT&CK tactics associated with this weakness class, not a working exploit. Not every attack uses every stage.
