NUUO NVRmini Devices vulnerability
NUUO NVRmini devices are vulnerable to OS command injection through the uploaddir parameter in writeuploaddir commands, enabling remote code execution.
Verdict
Today item — known-exploited.
An unauthenticated attacker can inject arbitrary shell commands via the uploaddir parameter, achieving remote code execution on affected NVRmini devices. The vulnerability has been exploited in the wild.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
3 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2024-12-18).
Probability (EPSS)
EPSS 0.93746 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: NUUO, NVRmini Devices. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-78 OS Command Injection — weakness family: Injection.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious writeuploaddir request with shell metacharacters in the uploaddir parameter.
Business
Surveillance infrastructure becomes a direct attack vector for initial network compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary commands on the NVRmini device with the privileges of the running process.
Business
Attackers gain persistent access to recorded video feeds and device resources.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish a foothold to pivot laterally into the broader network from the compromised NVR.
Business
Security perimeter is breached, enabling lateral movement to critical systems and data exfiltration.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
