# CVE-2026-128909: DJI AeroScope Mobile signature bypass in firmware update process Only affects the 1300 communications board firmware of DJI AeroScope Mobile (TP703) from 02.00.07.12 through 02.00.08.40. No fixed firmware is available. - Also known as: EUVD-2026-125352 - Severity: CVSS 8.8 (High), CNA - Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H - Known exploited (CISA KEV): no - Exposure: Unclear - Attention: Reference. No open trigger. (last checked 2026-11-13) - Fix: none listed; see the vendor advisory - Published: 2026-11-13 ยท Updated: 2026-11-13 CVE-2026-128909 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.8 (high) and affects AeroScope Mobile (TP703) and AeroScope Mobile (TP703) 1300 communications board firmware; no fixed version is listed; see the vendor advisory. ## Summary DJI AeroScope Mobile (TP703) and its 1300 communications board firmware accept firmware updates without verifying a cryptographic signature, which lets an attacker on the same local network, without logging in, install modified firmware and gain persistent code execution as root. The attacker reaches the board over the network through TCP port 16000, and the attack works only when the unit is not connected to another controlling host. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Who should check Operators of DJI AeroScope Mobile (TP703) units with 1300 communications board firmware that are reachable on TCP 16000 and not controlled by another host Source: https://cyber-defence-campus.github.io/projects/vulnerabilities/CVE-2026-128909/ ("Product: DJI / AeroScope Mobile (TP703)") ## Affected - DJI AeroScope Mobile (TP703): 03.00.00.26 - DJI AeroScope Mobile (TP703) 1300 communications board firmware: from 02.00.07.12, through 02.00.08.40 ## 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 - Check your stack: if you ship or depend on DJI AeroScope Mobile (TP703), DJI AeroScope Mobile (TP703) 1300 communications board firmware, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, run the stack.check operation (execute) on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - From the builder: [Sazabi](https://www.sazabi.com/?utm_source=cve-now&utm_medium=markdown&utm_content=CVE-2026-128909) is AI-native observability and security.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-128909 (entry last updated 2026-11-13): Affected: - DJI AeroScope Mobile (TP703): versions 03.00.00.26 - DJI AeroScope Mobile (TP703) 1300 communications board firmware: from 02.00.07.12, through 02.00.08.40 Fixed versions: none listed yet. Conditions (all must be true for the bug to be hit): - Affects DJI AeroScope Mobile (TP703) with 1300 communications board (source: https://cyber-defence-campus.github.io/projects/vulnerabilities/CVE-2026-128909/) - Attacker needs network access to TCP port 16000 on the board (source: https://cyber-defence-campus.github.io/projects/vulnerabilities/CVE-2026-128909/) - Board must not be controlled by another host (source: https://cyber-defence-campus.github.io/projects/vulnerabilities/CVE-2026-128909/) Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. Attacker needs: adjacent access, no login, no user action. Workaround: Connect the management Ethernet port only to an isolated network segment with no untrusted hosts, and do not route or bridge that segment to other networks. (source: https://www.cve.org/CVERecord?id=CVE-2026-128909) CISA KEV: CVE-2026-128909 is not listed as of cve.now's last read. This KEV status is for CVE-2026-128909 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked. Source: https://cve.now/CVE-2026-128909 ### What does this mean? Firmware updates on the 1300 communications board are not checked for a valid signature, so modified firmware can be installed. The advisory says this can give persistent code execution as root. Source: https://cyber-defence-campus.github.io/projects/vulnerabilities/CVE-2026-128909/, https://www.cve.org/CVERecord?id=CVE-2026-128909 ### Which versions are affected by CVE-2026-128909? AeroScope Mobile (TP703): version 03.00.00.26. AeroScope Mobile (TP703) 1300 communications board firmware: from 02.00.07.12 through 02.00.08.40. Source: https://cve.now/CVE-2026-128909 ### Am I affected, and how do I check? The affected firmware range is 02.00.07.12 through 02.00.08.40 on the 1300 communications board of the DJI AeroScope Mobile (TP703). The attack needs network access to TCP port 16000 on the board and only works while no other host is controlling the board. Compare the board's firmware version with that range.
