Sumavision Enhanced Multimedia Router (EMR) vulnerability
Sumavision Enhanced Multimedia Router (EMR) contains a cross-site request forgery vulnerability enabling unauthorized creation of administrator accounts.
Verdict
Today item — known-exploited.
An unauthenticated attacker can exploit CSRF to forge requests that create privileged user accounts on affected EMR devices, leading to complete administrative compromise without requiring direct authentication.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
1 independent public report 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 0.14666 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) · Affected: Sumavision, Enhanced Multimedia Router (EMR). 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-352 Cross-Site Request Forgery (CSRF) — weakness family: Web / client.CWE assignment from the public NVD record (may be stale); 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 602 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.

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 craft a malicious webpage or email containing a hidden request that, when visited by an authenticated EMR administrator, triggers account creation.
Business
Administrative access is compromised through social engineering, enabling unauthorized device control.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I establish a new administrator account with credentials I control, persisting my access even if the original compromise vector is discovered.
Business
Attackers gain persistent backdoor access to multimedia routing infrastructure, enabling long-term operational disruption.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the administrator account to modify device configurations, intercept traffic, or deploy additional malicious payloads across the network.
Business
Media distribution systems are compromised, risking service availability, content integrity, and potential data exfiltration.
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.
