Oracle ADF Faces vulnerability
Oracle ADF Faces contains an unsafe deserialization vulnerability allowing unauthenticated remote code execution. The flaw affects the library included in Oracle JDeveloper Distribution.
Verdict
Today item — known-exploited.
An unauthenticated attacker can exploit unsafe deserialization of untrusted data in Oracle ADF Faces to achieve remote code execution without authentication, posing critical risk to affected deployments.

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
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 2024-09-18).
Probability (EPSS)
EPSS 0.62478 — 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, ADF Faces. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-502 Deserialization of Untrusted Data — weakness family: Injection.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 883 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 serialized Java object and send it to an exposed ADF Faces endpoint.
Business
The organization's application server processes untrusted input without validation, creating an entry point for attackers.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
The vulnerable deserialization logic instantiates my malicious object, triggering gadget chain execution during object reconstruction.
Business
Arbitrary code executes with the privileges of the application server process, bypassing all authentication controls.
3
Lateral reach — past segmentation narrative 3
Attacker
I gain command execution on the underlying system and establish persistence or exfiltrate sensitive data.
Business
Attackers achieve full system compromise, enabling data theft, lateral movement, and operational disruption without credentials.
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.
