Assessment

Greenbone added public exploit-oriented tooling coverage for this Windows SMB remote-code-execution vulnerability. CISA lists it as known exploited globally.

Why it matters

  • Crafted packets to an affected SMBv1 server can enable remote code execution.
  • CISA records known ransomware campaign use, making exposed legacy SMB services important to remediate.

Evidence

2 record references and 1 source references passed trusted post-response validation. The current deterministic record contains 0 independent evidence groups.

Uncertainties

The tooling record does not establish current exploitation or successful execution.

First-party sensor telemetry is active; no disclosure-eligible deterministic observation is currently public for this CVE. This does not mean no activity was observed.

Next watchpoint

If you use affected Windows systems, disable SMBv1 where possible and apply Microsoft's remediation.

VTP deterministic assessment

Why this matters

  1. 01

    CISA KEV lists this vulnerability as known to be exploited globally.

  2. 02

    A proof of concept is reported; functional reliability is not established.

  3. 03

    EPSS is 0.90; this is predictive context, not exploitation evidence.

  4. 04

    First-party sensor telemetry is active; no disclosure-eligible deterministic observation is currently public for this CVE. This does not mean no activity was observed.
