Tenda AC1900 Router AC15 Model vulnerability
Tenda AC1900 Router AC15 contains a command injection vulnerability in the deviceName POST parameter, allowing remote attackers to execute arbitrary system commands.
Verdict
Today item — known-exploited.
Remote attackers can inject OS commands through an unvalidated POST parameter on the router's web interface, achieving unauthenticated code execution with device privileges. High exploitation activity observed in the wild.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
56 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 0.79673 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Tenda, AC1900 Router AC15 Model. 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 craft a malicious POST request with shell metacharacters embedded in the deviceName parameter to bypass input validation.
Business
Attacker gains code execution on the network perimeter device, establishing a foothold for lateral movement and data exfiltration.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute system commands to enumerate the network, modify firewall rules, or install persistent backdoors on the compromised router.
Business
Network traffic can be intercepted, redirected, or monitored; internal systems become exposed to further compromise.
3
Lateral reach — past segmentation narrative 3
Attacker
I pivot from the router to attack connected devices or intercept credentials and sensitive communications.
Business
Customer data, intellectual property, and operational continuity are at risk; incident response and remediation costs escalate.
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.
