CVE-2022-35733
Published: April 11, 2026
Official Description
Missing authentication for critical function vulnerability in UNIMO Technology digital video recorders (UDR-JA1004/JA1008/JA1016 firmware versions v1.0.20.13 and earlier, and UDR-JA1016 firmware versions v2.0.20.13 and earlier) allows a remote unauthenticated attacker to execute an arbitrary OS command by sending a specially crafted request to the affected device web interface.
Risk Analysis
UNIMO Technology digital video recorders (DVRs) have a critical vulnerability where missing authentication for a critical function allows a remote, unauthenticated attacker to execute arbitrary OS commands. The confirmed exploitation in the wild makes this a severe security risk.
This vulnerability is actively exploited in the wild. A remote, unauthenticated attacker can execute arbitrary OS commands by sending a specially crafted request to the affected device's web interface.
Update UNIMO Technology UDR-JA1004/JA1008/JA1016 DVRs to firmware versions later than v1.0.20.13, and UDR-JA1016 to firmware versions later than v2.0.20.13. Implement network segmentation and restrict access to DVR web interfaces from untrusted networks.
Technical Analysis
CVE-2022-35733 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-35733 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
