VMware Multiple Products vulnerability
VMware Workspace One Access and related products contain a command injection vulnerability in the administrative configurator. Authenticated attackers with network access can execute arbitrary OS commands with unrestricted privileges.
Verdict
Today item — known-exploited.
An authenticated network attacker who obtains valid configurator administrator credentials can inject and execute arbitrary commands on the underlying operating system, potentially compromising the entire identity management infrastructure and connected systems.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
8 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 0.23771 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: VMware, Multiple Products. 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 obtain valid credentials for the configurator administrator account through phishing, credential stuffing, or insider access.
Business
Administrative account compromise exposes the identity management system to unauthorized control and potential lateral movement.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I connect to the administrative configurator on port 8443 and inject shell metacharacters into input fields to break out of intended command context.
Business
Command injection allows attackers to bypass application logic and execute arbitrary system-level operations.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary commands with unrestricted OS privileges to install backdoors, exfiltrate data, or modify system configurations.
Business
Full operating system compromise of identity management infrastructure enables persistent access, data theft, and potential compromise of all dependent applications and user accounts.
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.
