Description
Parrot AR.Drone version 1 and 2 does not employ a suitable mechanism to prevent denial-of-service (DoS) attacks. An attacker can harm the device availability (i.e., video streaming and control) by using tool to perform an IPv4 flood attack. Verified attacks includes SYN flooding and UDP flooding.
Published: 2026-09-04
Score: 7.5 High
EPSS: < 1% Very Low
KEV: No
Impact: Denial of Service

AI Analysis

Impact

The vulnerability allows an attacker to degrade the availability of the Parrot AR.Drone by initiating IPv4 flood attacks. By sending large volumes of SYN or UDP packets, the device can be overwhelmed, causing loss of video streaming and control capabilities. This vulnerability is a classic denial‑of‑service flaw based on unprotected network interfaces.

Affected Systems

Parrot AR.Drone version 1 and version 2 are affected. No other product or firmware versions are listed as impacted.

Risk and Exploitability

The attack vector is network‑based and requires only the capability to send packets to the drone’s IP address; no authentication is needed. With no documented mitigation or patch at the time of this analysis, readily available tools could exploit the flaw. The CVSS score of 7.5 indicates a high‑severity denial‑of‑service vulnerability, and the EPSS score is not available, so the likelihood of exploitation cannot be precisely quantified. The vulnerability is not listed in the CISA KEV catalog. Overall, the risk remains high due to the ease of mounting a flood attack and the critical impact on drone availability.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest firmware update from Parrot that includes protection against TCP SYN and UDP flooding.
  • Configure network firewalls or access control lists to rate‑limit or block excessive SYN and UDP traffic toward the drone’s IP address.
  • Disable unused network services or ports on the AR.Drone to reduce the attack surface.
