Oracle E-Business Suite vulnerability
Oracle E-Business Suite contains an unspecified vulnerability allowing unauthenticated network attackers to compromise Web Applications Desktop Integrator via HTTP.
Verdict
Today item, not a backlog item.
Active exploitation in ransomware campaigns. Missing authentication control (CWE-306) enables direct network access to critical business application integration layer without credentials, presenting severe operational risk.

01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
587 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 2023-02-02), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.98342 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) · Affected: Oracle, E-Business Suite. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-306 Missing Authentication — weakness family: Authentication.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: yes · Technical Impact: totalCISA'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 107 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.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module, nuclei template. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

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 an HTTP request to the unauthenticated E-Business Suite endpoint without providing credentials.
Business
Attackers bypass authentication entirely, gaining direct access to application integration functions.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the missing access control to interact with Web Applications Desktop Integrator components.
Business
Critical business data flows through integrator become exposed to unauthorized manipulation and exfiltration.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence or lateral movement within the E-Business Suite environment.
Business
Ransomware operators gain foothold to encrypt financial, supply chain, and operational data systems.
4
Data at risk — exfiltration narrative 4
Attacker
I deploy encryption payloads across integrated business processes and databases.
Business
Enterprise operations halt; financial records, orders, and compliance data become inaccessible.
5
Lights out — disruption & extortion narrative 5
Attacker
I demand ransom for decryption keys while threatening data sale.
Business
Organization faces extortion, regulatory penalties, customer notification costs, and reputational damage.
04
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.
