No fix has been recorded since the CVE record was published in 2015 — use a compensating control (WAF / firewall / segmentation) and check the vendor's advisory.

Multiple cross-site scripting (XSS) vulnerabilities in the Wind Farm Portal application in Nordex Control 2 (NC2) SCADA 16 and earlier allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). 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".

Data Freshness Timeline

(refreshed 8× 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 87 of 133 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. 13 repeat rows among the latest 100 are merged into the row they repeat. The 46 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2015-6477?
CVE-2015-6477 is a medium-severity vulnerability; its CVE record was published on October 18, 2015. Multiple cross-site scripting (XSS) vulnerabilities in the Wind Farm Portal application in Nordex Control 2 (NC2) SCADA 16 and earlier allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
When was CVE-2015-6477 made public?
CVE-2015-6477 was made public on October 13, 2015: that is the date its CVE record's CNA, Cybersecurity and Infrastructure Security Agency (CISA) Industrial Control Systems (ICS), gives for when the vulnerability was made public. The CVE record itself was published on October 18, 2015. EchelonGraph's copy of the record carries a last-modified date of June 2, 2026; the record at its source may have been updated since.
Is CVE-2015-6477 actively exploited?
CVE-2015-6477 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 12% probability of exploitation in the next 30 days (96th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2015-6477?
CVE-2015-6477 has a CVSS v3.1 base score of 6.1 (CISA-ADP / Vulnrichment enrichment; NVD's own analysis pending).
How do I remediate CVE-2015-6477?
No fix for CVE-2015-6477 has been recorded since its CVE record was published in 2015. Restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and check the vendor's advisory for a fix. The vendor advisories EchelonGraph has for CVE-2015-6477 are linked in the Vendor Advisories panel on this page.
