CVE-2017-9136
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 · uneditedAn issue was discovered on Mimosa Client Radios before 2.2.3. In the device's web interface, there is a page that allows an attacker to use an unsanitized GET parameter to download files from the device as the root user. The attacker can download any file from the device's filesystem. This can be used to view unsalted, MD5-hashed administrator passwords, which can then be cracked, giving the attacker full admin access to the device's web interface. This vulnerability can also be used to view the plaintext pre-shared key (PSK) for encrypted wireless connections, or to view the device's serial number (which allows an attacker to factory reset the device).
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 confidenceMimosa Client Radios before 2.2.3 contain a path traversal vulnerability in the web interface where an unsanitized GET parameter allows unauthenticated attackers to download arbitrary files from the filesystem as root. This exposes unsalted MD5 hashes of admin passwords, plaintext wireless PSKs, and device serial numbers enabling factory reset.

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 device modelAccess the device web interface or check the device label to confirm it is a Mimosa Client Radio or Mimosa Backhaul RadioAffected if The device is a Mimosa Client Radio or Mimosa Backhaul Radio
-
Check the firmware versionLog into the web interface and navigate to the Status or Administration page to view the installed firmware version, or use the command line and run 'grep version /etc/os-release' or check the device dashboardAffected if The firmware version is 2.2.1 or earlier
-
Verify the web management interface is accessibleAttempt to access the device web interface over HTTP/HTTPS from a network-connected hostAffected if The web interface is reachable on the network
-
Confirm path traversal is exploitableSend a crafted GET request to the web interface with a path traversal sequence such as '../' to access files outside the web root (specific endpoint unknown from provided data)Affected if The device returns file contents from arbitrary filesystem paths, indicating the vulnerability is present
You are affected if the device is a Mimosa Client Radio or Backhaul Radio running firmware version 2.2.1 or earlier with an accessible web interface.

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 dataUpgrade Mimosa Client Radios to firmware version 2.2.3 or later to patch the path traversal vulnerability. If immediate patching is not possible, restrict network access to the device management interface.
