EchelonGraph scoreHIGH confidence

“▲” beside the score: it is higher than NVD's CVSS v2 base score.

Score elevated to 9.0 because this CVE is listed on ENISA's EU Known Exploited Vulnerabilities catalogue (Source: ENISA EUVD), indicating that ENISA records real-world exploitation of it. It is not on CISA's Known Exploited Vulnerabilities catalog. The 9.0 is the floor for confirmed exploitation, not an impact rating: this CVE's impact severity (EG Severity) is CVSS 6.8 MEDIUM under NVD CVSS v2.0. Confidence: HIGH.

EG Risk 71/100

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.

How it’s computed (value × EchelonGraph’s weight)

SSVC (CISA's decision table, applied by EchelonGraph)Track at low, Attend at medium and Act at high mission impact.

A fix is available. Apply it within your standard update timelines at low, sooner than that at medium and as soon as possible at high mission impact.

Exploitation active (ENISA EU KEV listing; Source: ENISA EUVD) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). EchelonGraph holds no SSVC assessment of this CVE from CISA: none of these inputs is from 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". CISA's decision table

BOD 26-04 (CISA's remediation timeline, Table 1)14 days if the affected system is publicly exposed; Fix on system upgrade if it is not.

The score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

Data Freshness Timeline

(refreshed 23× in last 7d / 63× 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 its CVE.org record (CNA or CISA ADP). An arrow marks a change the record states ("CVSS → 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). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.

Showing the most recent 100 of 239 rows on record for this CVE, as 99 entries (1 repeat merged).

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. 1 repeat row among the latest 100 is merged into the row it repeats. The 139 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(4)

What is CVE-2015-0279?
CVE-2015-0279 is a critical-severity vulnerability; its CVE record was published on March 26, 2015. JBoss RichFaces before 4.5.4 allows remote attackers to inject expression language (EL) expressions and execute arbitrary Java code via the do parameter.
When was CVE-2015-0279 made public?
CVE-2015-0279 was made public on March 24, 2015: that is the date its CVE record's CNA, Red Hat, Inc., gives for when the vulnerability was made public. The CVE record itself was published on March 26, 2015. EchelonGraph's copy of the record carries a last-modified date of May 6, 2026; the record at its source may have been updated since.
Is CVE-2015-0279 actively exploited?
CVE-2015-0279 is not currently on CISA's Known Exploited Vulnerabilities catalog. ENISA's EU Known Exploited Vulnerabilities catalogue lists CVE-2015-0279 (added October 25, 2026, reported by CNW): ENISA records its exploitation in the wild. Source: ENISA EUVD (EU Known Exploited Vulnerabilities catalogue), reproduced with acknowledgement. FIRST EPSS estimates a 3.9% probability of exploitation in the next 30 days (90th percentile of EPSS-scored CVEs).
How do I remediate CVE-2015-0279?
A fix for CVE-2015-0279 is available: update to the fixed version the vendor names in its advisory. The vendor advisories EchelonGraph has for CVE-2015-0279 are linked in the Vendor Advisories panel on this page.
