SAP NetWeaver vulnerability
SAP NetWeaver Application Server Java's Invoker Servlet lacks authentication, enabling remote code execution through HTTP/HTTPS requests.
Verdict
Today item — known-exploited.
An unauthenticated attacker can execute arbitrary code on affected SAP NetWeaver systems by sending crafted HTTP or HTTPS requests to the unprotected Invoker Servlet, leading to complete system compromise.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
7 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 2021-11-03).
Probability (EPSS)
EPSS 0.1745 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 10 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) · Affected: SAP, NetWeaver. 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.
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 2000 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.
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 the publicly accessible Invoker Servlet endpoint on the target SAP NetWeaver instance.
Business
The organization's SAP infrastructure is exposed to direct remote exploitation without credential requirements.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft an HTTP or HTTPS request containing malicious code and send it to the unprotected servlet.
Business
Attackers gain arbitrary code execution capability within the application server environment.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute commands with the privileges of the NetWeaver application server process.
Business
Critical business systems, data, and infrastructure controlled by SAP are compromised and at risk of theft or destruction.
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.
