“▲” beside the score: it is higher than NVD's CVSS score.

Score elevated to 7.2 because EPSS predicted 62% probability of exploitation within the next 30 days (99th percentile of EPSS-scored CVEs) when EchelonGraph scored this CVE. NVD baseline CVSS 4.7 retained for reference. Confidence: see factors.

Internet exposure · derived from Shodan data

61 internet-facing services (distinct ip:port) on record running a version that maps to CVE-2018-13380, in our KEV-Exposure radar’s Shodan-derived sample.

across 17 countries (United States, India, Italy, Canada, South Africa)top: fortios
See the KEV-Exposure radar →Derived from Shodan data. Shodan data is owned by Shodan, which holds its copyright (© Shodan). EchelonGraph claims no ownership of it or copyright in it. Aggregate, host-redacted.

How it counts: every 12 hours, when Shodan query credits allow, the radar runs one Shodan query per tracked product, reads up to 100 ip:port services per query, and keeps a service when its banner version matches a CISA-KEV or high-EPSS CVE; a service is dropped when neither a search nor a Shodan InternetDB port re-check has refreshed it for 21 days. A re-check that finds the port still listed by Shodan InternetDB refreshes the service without re-reading the banner, so a patched service can stay counted while its port stays open. A count is a banner-version inference over a sample, not an exploit test and not an internet-wide census, and the unit is a service, not a machine: a machine answering on two ports counts twice.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

No fix has been recorded since the CVE record was published in 2019. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation on your normal schedule.

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".

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).

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. 7 repeat rows among the latest 100 are merged into the row they repeat. The 54 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2018-13380?
CVE-2018-13380 is a high-severity vulnerability; its CVE record was published on June 4, 2019. A Cross-site Scripting (XSS) vulnerability in Fortinet FortiOS 6.0.0 to 6.0.4, 5.6.0 to 5.6.7, 5.4.0 to 5.4.12, 5.2 and below and Fortinet FortiProxy 2.0.0, 1.2.8 and below under SSL VPN web portal allows attacker to execute unauthorized malicious script code via the error or message handling…
When was CVE-2018-13380 made public?
CVE-2018-13380 was made public on May 24, 2019: that is the date its CVE record's CNA, Fortinet, Inc., gives for when the vulnerability was made public. The CVE record itself was published on June 4, 2019. EchelonGraph's copy of the record carries a last-modified date of November 21, 2024; the record at its source may have been updated since.
Is CVE-2018-13380 actively exploited?
CVE-2018-13380 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 62% probability of exploitation in the next 30 days (99th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2018-13380?
CVE-2018-13380 has a CVSS v3 base score of 4.7 (NVD). EchelonGraph synthesises NVD + FIRST EPSS into a combined EG score of 7.2 (HIGH).
How do I remediate CVE-2018-13380?
No fix for CVE-2018-13380 has been recorded since its CVE record was published in 2019. 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.
