KMW CCTV cameras contain a critical unauthenticated password reset vulnerability allowing remote attackers full access to camera feeds and settings.
CISA has published an advisory for KMW CCTV security cameras deployed across critical infrastructure sectors worldwide. The affected products, KM-IP521 and KM-IP421 models, contain a critical vulnerability (CVE-2026-5386) that allows unauthenticated remote attackers to reset the administrator password to a known value, granting complete access to camera feeds and configuration settings. This represents a significant security risk for organizations using these cameras in commercial facilities, government services, critical manufacturing, financial services, and transportation systems.
KMW, the Romania-based manufacturer, has released a firmware update to address the vulnerability, available at their official website. Organizations deploying the patch should note that KM-IP421 devices will lose cloud authorization and require customer support contact to re-establish P2P connections. KMW recommends deploying surveillance equipment on isolated networks, restricting internet access to specific devices, and maintaining regular firmware update cycles. CISA emphasizes implementing defense-in-depth strategies, including network segmentation and VPN-based remote access where required.
No known public exploitation has been reported to CISA at this time. However, the critical severity and ease of exploitation make this vulnerability a high-priority remediation target for organizations operating these camera systems in sensitive environments.

Detection guidance
Repeated Authentication Failures Against IP Camera Admin Interface
Detects a burst of failed login attempts against network camera/IoT device management interfaces, consistent with password guessing or brute-force attempts against exposed CCTV administration portals (e.g., KMW KM-IP521/KM-IP421). Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

id: 3a048691-e3fb-5baa-a84b-ac0ffe359985
status: experimental
description: 'Identifies repeated authentication failures against network camera or
IoT device
administration interfaces, which may indicate password guessing/brute-force activity
such as attempts to exploit the KMW KM-IP521/KM-IP421 password reset vulnerability
or generic credential brute-forcing against exposed camera web management ports.
This rule expects device authentication logs (syslog, web server access logs, or
authentication event forwarders) that expose a status/result field for login attempts.
Because a single event cannot represent a brute-force pattern, alerting logic should
aggregate on source IP and destination device over a short window (e.g., 5+ failures
within 5 minutes) at the SIEM correlation layer; this rule flags the qualifying
failure events for that correlation.

Successful Camera Login Immediately Following Failed Authentication Burst
Detects a successful authentication event to an IP camera/IoT device management interface occurring shortly after a burst of failed logins, indicating potential use of a guessed, reset, or known default credential to gain unauthorized valid account access. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

status: experimental
description: 'Flags successful authentication events to camera/IoT device management
interfaces.
When correlated at the SIEM layer with a preceding burst of failed logins from the
same source against the same device (see companion password-guessing rule), this
pattern is consistent with abuse of a known/reset administrator credential such
as
the one exposed by CVE-2026-5386 affecting KMW KM-IP521/KM-IP421 cameras, or use
of
unchanged default vendor credentials to obtain Valid Account access.
