CVE-2025-8183: NULL Pointer Dereference in µD3TN Leading to Denial of Service (DoS) Attack

Views: 220

Overview

The CVE-2025-8183 vulnerability is a critical flaw that exists within the µD3TN software where a NULL Pointer Dereference error can be exploited via the destination Endpoint Identifier. This vulnerability potentially affects all systems and networks utilising this software, leading to system compromise or data leakage. Given the severity score of 7.5, it is crucial that administrators take immediate action to mitigate this vulnerability.

How the Exploit Works

A remote attacker can exploit this vulnerability by sending a carefully crafted network request to the non-singleton destination Endpoint Identifier of the µD3TN software. This causes a NULL Pointer Dereference, leading to a crash in the system and hence, a denial of service. It’s possible that, in some circumstances, this could be further exploited to execute arbitrary code on the system, leading to a full system compromise.

Conceptual Example Code

Here is a conceptual HTTP POST request that might trigger the vulnerability:

POST /uD3TN/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "destination": null }

In this example, the “destination” field is intentionally set to null, which could cause the NULL Pointer Dereference in the µD3TN application.

Mitigation

Users of affected versions of µD3TN should apply the latest vendor patches immediately. If unable to apply the patch immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation, blocking malicious requests that attempt to exploit this vulnerability.
