Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Ro vulnerability
Cisco Small Business RV320 and RV325 routers contain an input validation flaw in the web management interface allowing authenticated administrators to execute arbitrary commands.
Verdict
Today item — known-exploited.
An authenticated administrative user can exploit improper input validation in the management interface to run arbitrary commands on affected Cisco Small Business VPN routers, potentially compromising network infrastructure and connected systems.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
12 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 2022-03-03).
Probability (EPSS)
EPSS 0.95923 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Cisco, Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-20 Improper Input Validation.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 gain administrative access to the router's web management interface through credential compromise or insider access.
Business
An attacker with administrative privileges can bypass security controls designed to protect the device.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I submit specially crafted input to the management interface that bypasses input validation checks.
Business
The organization loses assurance that the management interface properly sanitizes user-supplied data.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary system commands on the router with the privileges of the management process.
Business
The router is fully compromised, allowing attackers to intercept traffic, modify configurations, or pivot to internal networks.
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.
