VIVOTEK Camera Firmware
CISA warns a CVSS 10 command injection in many VIVOTEK cameras can allow unauthenticated root command execution.
CISA advisory ICSA-26-272-03 covers CVE-2026-22755, a command-injection flaw (CWE-77) in firmware used by dozens of VIVOTEK network camera models across V, C, S, Dome, Panoramic, and Bullet lines. The issue scores CVSS 10.0 with network access, no privileges, and no user interaction, and may allow remote command execution, potentially as root. CISA found a public proof of concept authored by indoushka. CISA reports no known public exploitation targeting the vulnerability.
- CVE-2026-22755 scores CVSS 10.0 for command injection.
- Remote command execution may occur with root privileges.
- Dozens of VIVOTEK dome, bullet, and panoramic models are affected.
- CISA identified a public proof of concept by indoushka.

|---|---|---|---|---|---|---|---|
| CVE-2026-22755 | OS Command Injection in Vivotek 9-Series IP Camera Firmware CVE-2026-22755 is an OS command injection flaw (CWE-77, improper neutralization of special elements used in a command) in the firmware of 36 Vivotek network camera models spanning the FD, FE, IB, IP, IT, MA, MS and TB 9-series lines. Per the CVSS 4.0 vector, it is exploitable over the network with no privileges required and no user interaction, meaning an attacker can send crafted input to a network-facing service in the camera firmware and have arbitrary operating-system commands executed on the device. Successful exploitation carries high impact to the camera's confidentiality, integrity and availability - and to subsequent systems - consistent with full device compromise and potential lateral movement into the surrounding surveillance network. Any deployment running one of the listed models on one of the 20 listed firmware module versions (0100a through 0125c) is affected, with directly internet-exposed cameras at greatest risk. No public proof of concept or confirmed in-the-wild exploitation is known (not yet in CISA KEV), but EPSS assigns a 20.7% probability of exploitation within 30 days (97th percentile), making this a high-priority patching target. |

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability.
- Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
- Locate control system networks and remote devices behind firewalls and isolating them from business networks.
- When remote access is required, use more secure methods, such as virtual private networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
