CVE-2020-29020
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Access Control vulnerability in web service of Secomea SiteManager allows remote attacker to access the web UI from the internet using the configured credentials. This issue affects: Secomea SiteManager All versions prior to 9.4.620527004 on Hardware.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Secomea SiteManager web service has an Improper Access Control vulnerability that allows remote attackers to access the web UI from the internet using valid credentials. This indicates the web interface is exposed to WAN when it should be restricted to internal networks or VPN access only, enabling external attackers to reach the authentication portal.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Secomea SiteManager installationLocate the Secomea SiteManager device on your network. This is typically a physical appliance or virtual instance. Note its network IP address and confirm it is a Secomea product.Affected if You have a Secomea SiteManager device deployed in your environment
-
Check installed firmware versionLog into the SiteManager web interface or access the device via CLI/SSH. Navigate to the system information or firmware version section. Compare the displayed version number to 9.4.620527004.Affected if The installed firmware version is less than 9.4.620527004
-
Verify web UI network exposureFrom an external network (or use an online port scanner), attempt to reach the SiteManager web interface using its public IP address on common web ports (80, 443, 8080, 8443). Alternatively, review firewall or NAT rules to determine if inbound HTTP/HTTPS traffic to the SiteManager is permitted from internet-facing interfaces.Affected if The SiteManager web UI is reachable from the internet/WAN without VPN tunnel or internal network restriction
You are affected if your Secomea SiteManager runs firmware version below 9.4.620527004 AND the web interface is directly accessible from the internet rather than restricted to trusted internal networks or VPN connections.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data9.4.620527004
Upgrade SiteManager to version 9.4.620527004 or later and ensure the web UI is not directly internet-exposed by implementing proper network segmentation or firewall rules to restrict access to trusted networks only.
