CVE-2022-36555
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 · uneditedHytec Inter HWL-2511-SS v1.05 and below implements a SHA512crypt hash for the root account which can be easily cracked via a brute-force attack.
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 Hytec Inter HWL-2511-SS v1.05 and below uses SHA512crypt for root password hashing in a way that makes the hash vulnerable to trivial brute-force cracking, likely due to missing or inadequate salting, insufficient iterations, or use of default/weak credentials. This allows unauthenticated attackers to obtain the root password and gain full administrative control of the device.

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 device modelAccess the device via SSH or web interface and check the system information or banner for 'Hytec HWL-2511-SS' or 'Inter HWL-2511-SS' model identificationAffected if The device model is Hytec Inter HWL-2511-SS
-
Check firmware versionRun 'show version' via SSH or check the web interface firmware/version page to determine the installed firmware versionAffected if Firmware version is 1.05 or below, or the version cannot be determined (treat as affected)
-
Verify root SSH access statusCheck if root SSH login is enabled by reviewing SSH configuration or attempting to connect as root; check if SSH port 22 is exposed to untrusted networksAffected if Root SSH access is enabled and accessible from external/untrusted networks
-
Check for default or weak credentialsAttempt to login with default root credentials (check vendor documentation for defaults) or examine if password hashing configuration uses weak methods; if you have CLI access, check /etc/shadow or equivalent for password hash formatAffected if Default credentials still work or password hashes use weak SHA512crypt without proper salting/iterations
The environment is affected if the device is a Hytec Inter HWL-2511-SS running firmware version 1.05 or below with root SSH access enabled and exposed, especially if default or weak password hashing is in use.

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 dataUpdate to a patched firmware version that implements properly salted, high-iteration password hashing (e.g., bcrypt, Argon2) or apply vendor-supplied hardening; if unavailable, disable root SSH access, enforce network segmentation, and monitor for brute-force attempts.
