Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.13% for the current model date.

Compensating controls

  • Apply the linked authoritative mitigation while planning the permanent fix.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Kiloview P1/P2 and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

The device is observed to accept deprecated TLS protocols, increasing the risk of cryptographic weaknesses.

What

The device is observed to accept deprecated TLS protocols, increasing the risk of cryptographic weaknesses.

Why

The product uses a broken or risky cryptographic algorithm or protocol.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
an adjacent network → Use of a Broken or Risky Cryptographic Algorithm → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-327 ↗

CWE-327: Use of a Broken or Risky Cryptographic Algorithm. The product uses a broken or risky cryptographic algorithm or protocol.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

Official advisory ↗
NCSC-NL · Dutch · NCSC-2024-0273Kwetsbaarheden ontdekt in Kiloview P1 4G Video Encoder en P2 4G Video Encoder

De firmware maakt gebruik van een aantal hard-coded credentials, waardoor een kwaadwillende toegang kan krijgen tot het systeem. Ook is het mogelijk om zonder authenticatie de firmware te vervangen, waardoor de werking van het systeem kan worden gemanipuleerd. Er is geen encryptie op de configuratie webinterface waardoor een aanvaller de communicatie kan afluisteren en credentials kan onderscheppen. Elk van de kwetsbaarheden afzonderlijk maakt misbruik mogelijk. In keten echter, is totale overname van het systeem mogelijk, waarmee de kwaadwillende volledige controle heeft over het systeem en de streaming data.

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Mitigation available
Affected
P1/P2: All ≤ 4.8.2605
Fixed
No fixed version is explicitly recorded in the structured CVE data.
Action
De leverancier heeft besloten de kwetsbaarheden niet te verhelpen in de meest recente update van de firmware. Bij navraag door het NCSC geeft de leverancier ook geen indicatie van een oplossingstermijn. Wel heeft de leverancier updates uitgebracht voor de centrale serversystemen om misbruik daar tegen te gaan. Het NCSC adviseert daarom dan ook om op basis van deze informatie een risico-afweging te maken omtrent de inzet en het gebruik van deze systemen.
Workaround
No verified workaround is recorded. Limit untrusted access and use least privilege until authoritative guidance is available.
