Apache OFBiz vulnerability
Apache OFBiz contains an incorrect authorization vulnerability allowing unauthenticated remote code execution through Groovy payload injection in the OFBiz user process.
Verdict
Today item — known-exploited.
An unauthenticated attacker can bypass authorization controls to inject and execute arbitrary Groovy code within OFBiz, achieving remote code execution. This vulnerability is actively exploited in the wild with high exploit probability.

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
27 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 2024-08-27).
Probability (EPSS)
EPSS 0.99427 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) · Affected: Apache, OFBiz. 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-863 Incorrect Authorization — weakness family: Authorization / access control.CWE — CNA-assigned (CVE.org); 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 22 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.
02
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 identify that OFBiz fails to properly enforce authorization on a code execution endpoint, allowing unauthenticated access.
Business
The organization's OFBiz deployment is exposed to unauthorized access without requiring valid credentials.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft a malicious Groovy payload and submit it through the vulnerable endpoint in the OFBiz user process context.
Business
Arbitrary code executes with OFBiz application privileges, bypassing all authentication and authorization controls.
3
Lateral reach — past segmentation narrative 3
Attacker
I achieve remote code execution and establish persistence or lateral movement within the compromised system.
Business
The attacker gains full control of the OFBiz application server and potentially the underlying infrastructure.
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.
