CVE-2018-13801
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 · uneditedA vulnerability has been identified in ROX II (All versions < V2.12.1). An attacker with network access to port 22/tcp and valid low-privileged user credentials for the target device could perform a privilege escalation and gain root privileges. Successful exploitation requires user privileges of a low-privileged user but no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the system.
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 · high confidenceA privilege escalation vulnerability exists in ROX II versions prior to V2.12.1. An attacker with valid low-privileged user credentials and network access to SSH (port 22/tcp) can escalate to root privileges without any user interaction, compromising the device's confidentiality, integrity, and availability.

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 the ROX II firmware versionAccess the device management interface or use command line tools like 'show version' or 'cat /etc/version' to retrieve the installed firmware version. Check the firmware release notes or system information page for the exact version number.Affected if The installed version is below V2.12.1 (e.g., V2.12.0, V2.11.x, or earlier)
-
Verify SSH service is enabledCheck the device's running services or configuration to confirm that SSH (port 22/tcp) is enabled. This can be done via the management web interface under services/settings, or by checking firewall/network service configurations.Affected if SSH is enabled and accessible on the network (port 22/tcp is open)
-
Check for existing low-privileged user accountsReview the device's user database or authentication settings to identify accounts with non-root privileges. Use commands like 'show users' or examine /etc/passwd if accessible via limited shell.Affected if There are one or more non-root user accounts configured on the system
-
Confirm network accessibility to SSHVerify that the device's SSH port (22/tcp) is reachable from untrusted networks by scanning the device from an external location or checking firewall rules that permit SSH traffic.Affected if SSH port 22 is exposed to networks outside the trusted management network
The environment is affected if the ROX II firmware version is below V2.12.1 AND SSH is enabled with at least one low-privileged user account accessible from the network.

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 data2.12.1
Upgrade ROX II to version V2.12.1 or later. If immediate patching is not possible, restrict SSH access to trusted management networks and enforce strong credential policies for low-privileged accounts.
