TVT NVMS-1000 vulnerability
TVT NVMS-1000 devices contain a directory traversal vulnerability allowing attackers to access files outside intended directories via crafted GET requests.
Verdict
Today item — known-exploited.
Directory traversal in NVMS-1000 enables unauthorized file access. The high EPSS score and confirmed wild exploitation indicate active abuse. Affected organizations should prioritize patching or isolating vulnerable instances.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
1 independent public report 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 2021-11-03).
Probability (EPSS)
EPSS 0.96071 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: TVT, NVMS-1000. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.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 GET requests with path traversal sequences to bypass directory restrictions and access sensitive files on the target device.
Business
Confidential data stored on affected devices becomes accessible to unauthorized parties, creating compliance violations and operational risk.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I retrieve configuration files, credentials, or system information from the device to facilitate further compromise or lateral movement.
Business
Exposed credentials and system details enable attackers to escalate privileges or pivot to connected infrastructure, expanding the breach scope.
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.
