VMware SD-WAN Edge vulnerability
VMware SD-WAN Edge contains a command injection vulnerability in the local web UI that allows remote code execution.
Verdict
Today item — known-exploited.
A command injection flaw in VMware SD-WAN Edge's web interface enables unauthenticated attackers to execute arbitrary commands with system privileges, leading to complete infrastructure compromise.
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
129 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 2022-03-25).
Probability (EPSS)
EPSS 0.86431 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: VMware, SD-WAN Edge. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-78 OS Command Injection — weakness family: Injection.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
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 SD-WAN Edge web UI endpoint and craft a malicious input containing shell metacharacters to break out of intended command context.
Business
Network edge devices lose integrity; attackers gain persistent access to branch office infrastructure and can pivot to internal networks.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary system commands through the injected payload, establishing reverse shells or deploying malware directly on the compromised device.
Business
Operational technology and data flows through SD-WAN are intercepted, exfiltrated, or corrupted; business continuity is disrupted across multiple sites.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the compromised edge device as a foothold to scan internal networks, harvest credentials, and move laterally toward critical systems.
Business
Enterprise security perimeter is breached; sensitive data and intellectual property become accessible to threat actors.
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.
