CVE-2017-2740
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 potential security vulnerability has been identified with the command line shell of the HP ThinPro operating system 6.1, 5.2.1, 5.2, 5.1, 5.0, and 4.4. The vulnerability could result in a local unauthorized elevation of privilege on an HP thin client 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 · moderate confidenceA local privilege escalation vulnerability exists in the command line shell of HP ThinPro operating system versions 6.1, 5.2.1, 5.2, 5.1, 5.0, and 4.4. An authenticated local attacker could exploit this vulnerability to gain elevated privileges beyond their current authorization level on the thin client 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 HP ThinPro OS versionAccess the thin client system settings or boot information to retrieve the ThinPro version number. This can typically be found in the system information panel, at the login screen, or by running 'uname -a' or 'cat /etc/version' if shell access is available.Affected if The displayed version matches 4.4, 5.0, 5.1, 5.2, 5.2.1, or 6.1 exactly.
-
Verify command line shell access is availableDetermine if the thin client has a command line interface or terminal accessible to local users. This may be through a dedicated terminal application, SSH access, or emergency recovery mode.Affected if The command line shell or terminal functionality is enabled and accessible to local authenticated users.
-
Check current user privilege levelAfter accessing the shell, run 'whoami' or 'id' to determine the current user's permissions and group memberships.Affected if The current user is an authenticated local user without administrator or root privileges, but has shell access.
A user is affected if they are running any of the exact versions 4.4, 5.0, 5.1, 5.2, 5.2.1, or 6.1 of HP ThinPro and have authenticated local access to the command line shell, as the privilege escalation requires accessing the CLI with a low-privilege account.
