SAP NetWeaver vulnerability
SAP NetWeaver Visual Composer Metadata Uploader allows unauthenticated file upload of executable binaries, enabling remote code execution and lateral movement.
Verdict
Today item, not a backlog item.
An unauthenticated attacker can upload malicious executables to NetWeaver systems without authentication, leading to code execution. Active exploitation and ransomware deployment have been observed in the wild.

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
361 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 2025-04-29), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.99512 — 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 — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-434 Unrestricted File Upload — weakness family: Path traversal / file.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 5 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 public proof-of-concept / detection template). Catalog entries: 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 upload a malicious executable file through the unprotected Metadata Uploader endpoint without credentials.
Business
Attackers gain initial foothold on SAP infrastructure with no authentication barrier.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute the uploaded binary to achieve remote code execution on the NetWeaver server.
Business
Adversaries obtain command execution privileges within critical enterprise systems.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the compromised NetWeaver instance to move laterally across the SAP environment and connected networks.
Business
Breach scope expands from isolated vulnerability to enterprise-wide system compromise.
4
Data at risk — exfiltration narrative 4
Attacker
I deploy ransomware payloads across affected systems to encrypt business-critical data.
Business
Operations halt, data becomes inaccessible, and ransom demands threaten business continuity.
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.
