CVE-2017-16249

NVD-CWE-noinfoPublished: November 10, 2017· Updated: Jun 17, 2026

7.5

CVSS v3.1

Official Description

The Debut embedded http server contains a remotely exploitable denial of service where a single malformed HTTP POST request can cause the server to hang until eventually replying (~300 seconds) with an HTTP 500 error. While the server is hung, print jobs over the network are blocked and the web interface is inaccessible. An attacker can continuously send this malformed request to keep the device inaccessible to legitimate traffic.

Technical Analysis

CVE-2017-16249 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 7.5.

A proof-of-concept (PoC) exploit exists for CVE-2017-16249. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
