The only prerequisite is a valid email account on the target Exchange server — no administrative privileges or special roles are required.</p> <p>The vulnerability was reported as a denial of service; however, the underlying deserialization primitive may carry remote code execution potential given the right gadget chain. No RCE gadget was identified during our research.</p>
