Move 4K 12X: Missing Authentication for Critical Functionality
CVE-2026-75969 is a critical-severity missing authentication for critical functionality vulnerability in Move 4K 12X from PTZOptics, with a CVSS 4.0 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 0.0.98 as the first without the flaw, so updating Move 4K 12X to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Move 4K 12X to 0.0.98 or a later version.
- Update Move 4K 20X to 0.1.33 or a later version.
- Update Move 4K 30X to 2.1.17 or a later version.
- Read the advisory on psirt.havsys.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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

The underlying weakness: Missing Authentication for Critical Functionality
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
