No fix has been recorded since the CVE record was published in 2014 — if the vendor still supports the product, apply the fixed version it names; if not, isolate the affected system (restrict network access to it, for example with a firewall, or keep it off the internet) or retire the product.

The CVE record's CNA (CERT/CC) lists MW6 Tech MW6 Aztec ActiveX Controls versions before 4.0; MW6 Tech MW6 DataMatrix ActiveX Controls versions before 4.0; MW6 Tech MW6 MaxiCode ActiveX Controls versions before 4.0 as affected. No release containing a fix is confirmed on record.

MW6 Aztec, DataMatrix, and MaxiCode ActiveX controls before version 4.0 vulnerable to arbitrary code via a crafted HTML document. Latest versions (4.0) of MW6 Aztec, DataMatrix, and MaxiCode ActiveX controls have resolved the issue

No fix has been recorded since the CVE record was published in 2014. If the vendor still supports the product, apply the fixed version it names within your standard update timelines at low or medium mission impact and sooner than that at high; if it no longer does, isolate the affected system (restrict network access to it, for example with a firewall, or keep it off the internet) or retire the product.

EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

(refreshed 9× in last 7d / 21× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 86 of 130 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 14 repeat rows among the latest 100 are merged into the row they repeat. The 44 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
