PTZOptics cameras: Missing authentication in firmware upload
Summary
Multiple PTZOptics PTZ cameras and the Firmware Upgrade Tool accept firmware updates without authentication. An unauthenticated attacker with network access to the device can install modified firmware without administrator credentials, which may allow persistent manipulation of the camera. The CVSS 4.0 base score is 9.1 (critical). Exposure depends on whether the cameras are reachable from the internet or untrusted network segments.
Affected
- Move 4K 12X before 0.0.98, Move 4K 20X before 0.1.33, Move 4K 30X before 2.1.17
- Link 4K 12X before 0.0.99, Link 4K 20X before 0.1.37, Link 4K 30X before 2.1.18
- Move SE 12X before 9.1.66, Move SE 20X before 9.1.44, Move SE 30X before 9.1.46
- Studio 4K 12X/20X and Studio SE 12X/20X before 8.3.32
- All Generation 2 cameras (including PT12X/PT20X/PT30X-SDI/NDI/USB-G2, PTEPTZ-ZCAM-G2, PTVL-ZCAM, PT12X/PT20X-ZCAM)
- Studio Pro (all versions)
- Upgrade Tool (all versions)
Fixed in
- Move 4K 12X 0.0.98, Move 4K 20X 0.1.33, Move 4K 30X 2.1.17
- Link 4K 12X 0.0.99, Link 4K 20X 0.1.37, Link 4K 30X 2.1.18
- Move SE 12X 9.1.66, Move SE 20X 9.1.44, Move SE 30X 9.1.46
- Studio 4K 12X/20X and Studio SE 12X/20X 8.3.32
- Generation 2 cameras, Studio Pro, Upgrade Tool and ZCAM models: Unknown.
Workaround
- Disable network services until the firmware can be updated.
- Restrict access to the camera to a trusted management VLAN.
- Keep cameras off the internet and do not port-forward management interfaces.
Exploitation
- In the wild: Unknown.
- Public proof of concept: Unverified. One source reports none, but it is unreliable.
- CISA SSVC: Exploitation none, automatable yes, technical impact total.
Our recommendation
- Inventory all PTZOptics devices with model and firmware version.
- Update Move 4K, Link 4K, Move SE and Studio models to the fixed versions after checking the vendor advisory.
- Ask the vendor whether Generation 2, ZCAM, Studio Pro and Upgrade Tool devices have a fix, and isolate them until then.
- Keep cameras off the internet and place them in a separate camera VLAN.
- Monitor the vendor PSIRT and CISA for updates.

Original description (NVD)
Missing authentication for critical function vulnerability for all PTZOptics cameras and the Firmware Upgrade Tool - Firmware Update modules. A missing authentication vulnerability in the firmware update mechanism of affected PTZOptics cameras allows an unauthenticated user to install modified firmware on the device without administrator credentials. This vulnerability allows attackers to upload modified firmware to the device without admin credentials. This issue affects: * Move 4K 12X before: 0.0.98 * Move 4K 20X before: 0.1.33 * Move 4K 30X before: 2.1.17 * Link 4K 12X before: 0.0.99 * Link 4K 20X before: 0.1.37 * Link 4K 30X before: 2.1.18 * Move SE 12X before: 9.1.66 * Move SE 20X before: 9.1.44 * Move SE 30X before: 9.1.46 * Studio 4K 12X before: 8.3.32 * Studio 4K 20X before: 8.3.32 * Studio SE 12X before: 8.3.32 * Studio SE 20X before: 8.3.32 * All Generation 2 cameras, including: PT12X-SDI-GY-G2, PT12X-SDI-WH-G2, PT12X-NDI-GY-G2, PT12X-NDI-WH-G2; PT12X-USB-GY-G2, PT12X-USB-WH-G2; PT20X-SDI-GY-G2, PT20X-SDI-WH-G2, PT20X-NDI-GY-G2, PT20X-NDI-WH-G2; PT20X-USB-GY-G2, PT20X-USB-WH-G2; PT30X-SDI-GY-G2, PT30X-SDI-WH-G2, PT30X-NDI-GY-G2, PT30X-NDI-WH-G2; PTVL-ZCAM, PTVL-NDI-ZCAM; PTEPTZ-ZCAM-G2, PTEPTZ-NDI-ZCAM-G2; PT12X-ZCAM, PT12X-NDI-ZCAM; PT20X-ZCAM, PT20X-NDI-ZCAM; Studio Pro - All versions * Upgrade Tool - All versions
