Oracle Fusion Middleware vulnerability
An unspecified vulnerability in Oracle Fusion Middleware's Application Server Single Sign-On component allows remote attackers to compromise integrity through unknown vectors. The vulnerability is classified as an open redirect issue (CWE-6
Verdict
Today item — known-exploited.
Remote attackers can exploit this vulnerability without authentication to redirect users or manipulate security-sensitive operations. Active exploitation in the wild indicates practical attack capability. Organizations running affected Fusion Middleware versions face integrity compromise risks.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
2 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2022-03-28).
Probability (EPSS)
EPSS 0.04664 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 4.7 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N) · Affected: Oracle, Fusion Middleware. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
Weakness (CWE)
Mapped to CWE-601 Open Redirect — weakness family: Web / client.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: partialCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 3450 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious URL containing a redirect parameter targeting the SSO component to deceive users into visiting attacker-controlled sites.
Business
User trust in authentication systems erodes as phishing attacks succeed through legitimate-appearing redirects, increasing credential theft and account compromise incidents.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I intercept or manipulate SSO session data through the redirect mechanism to escalate privileges or access unauthorized resources within the Fusion Middleware environment.
Business
Attackers gain unauthorized access to sensitive business applications and data, violating compliance requirements and exposing confidential information across enterprise systems.

What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
