CVE-2026-128909

Description

Improper verification of cryptographic signature (CWE-347) in the firmware update handler of the management service (uavmonitor_usbv1) of the 1300 communications board in DJI AeroScope Mobile (TP703) firmware 03.00.00.26, with 1300 communications board firmware 02.00.07.12 through 02.00.08.40, allows an unauthenticated attacker on the local network to install modified firmware, which gives persistent code execution as root. The device accepts any image that matches an MD5 checksum supplied in the same request and does not verify a signature. Exploitation requires network access to TCP port 16000 on the board and that the unit is not connected to another controlling host. Reproduced by running the unmodified device binaries in emulation; not tested on a physical device. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. DJI has discontinued AeroScope Mobile and no fixed firmware is available.

What to do

• DJI AeroScope Mobile has been discontinued and is no longer supported by DJI. No fixed firmware is available. Operators should plan to replace affected units with a supported product and, until then, apply the workarounds.CNA solution statement
• Connect the unit's management Ethernet port only to an isolated network segment with no untrusted hosts, and do not route or bridge that segment to other networks, so that TCP port 16000 and the multicast discovery traffic (225.0.0.37, UDP port 16001) cannot be reached. The device has no setting that enables signature checking of firmware updates.CNA workaround statement

Historical context and remediation

This reference retains the original CVE publication date. A recent record update does not mean a new attack occurred.

No separately sourced impact summary is available on this page yet. Consult the description, version data and dated exploitation evidence.

Version statuses below come from the CNA. An “unaffected” version is not necessarily a currently supported release or proof of a patch date. EPSS is a dated risk estimate, not a count of historical attacks.
