CVE-2026-78321: CWE-770 Allocation of Resources Without Limits or Throttling in DJI Neo
CVE-2026-78321 is a resource exhaustion vulnerability in the HTTP media server of various DJI drone models. The server does not sufficiently limit incoming connections or request rates, allowing an attacker on the drone's internal network to exhaust the connection pool by repeatedly requesting stored media files. This results in a denial of service that prevents the DJI Fly application from retrieving photos and videos in QuickTransfer mode. A firmware update from DJI is required to remediate this issue.
AI Analysis
Technical Summary
The HTTP media server on affected DJI drones lacks adequate limits on incoming connections and request rates. An attacker with access to the internal network can repeatedly request stored media files, exhausting the server's connection pool. This denial of service prevents legitimate requests, specifically blocking the DJI Fly application from accessing media files via QuickTransfer mode. Affected models include DJI Neo, Neo 2, Flip, Air 3, Air 3S, Avata 2, Avata 360, Mavic 3 series, Mini 2, Mini 3 series, Mini 4 Pro, and Mini 5 Pro up to specified firmware versions. Remediation requires a vendor firmware update, though no patch details or advisories are currently available.
Potential Impact
Successful exploitation leads to denial of service on the drone's HTTP media server, preventing the DJI Fly application from retrieving photos and videos. This disrupts normal media transfer operations but does not indicate code execution or data compromise. The impact is limited to availability of media retrieval functionality over the affected interface.
Mitigation Recommendations
A firmware update from DJI is required to remediate this vulnerability. Patch status is not yet confirmed—check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the drone's internal network to trusted users only to prevent exploitation.
