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 · uneditedDell ThinOS 10, versions prior to 2605_10.2100, contain an Obsolete Feature in UI vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Unauthorized access.
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 confidenceDell ThinOS 10 versions prior to 2605_10.2100 contain an obsolete feature in the user interface that can be exploited by a low-privileged attacker with local physical or console access, potentially leading to unauthorized access to system functions or data.

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 installed ThinOS 10 versionAccess the ThinOS system information orAbout page in the UI, or use the system management interface to retrieve the OS build/version numberAffected if The version number is lower than 2605_10.2100
-
Verify the obsolete UI feature existsInspect the ThinOS user interface for legacy or obsolete UI components or menus that may have been present in prior versions - check for unused or deprecated UI elements in the system settings or administration menusAffected if Any obsolete or deprecated UI feature is present and accessible in the interface
-
Confirm console or physical access existsEvaluate whether the thin client devices are located in areas where unauthorized physical or console access is possible - check physical security controls and console access policiesAffected if Low-privileged individuals can gain physical or console access to the thin client devices
You are affected if your ThinOS 10 version is prior to 2605_10.2100 and the obsolete UI feature is accessible to low-privileged users with physical or console access.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpgrade Dell ThinOS 10 to version 2605_10.2100 or later to remove or disable the obsolete UI feature. If immediate patching is not possible, restrict physical and console access to thin client devices.
Dell ThinOS 10 version 2605_10.2100 or later
- 1. Identify the current Dell ThinOS 10 version installed on affected systems
- 2. Verify the current version is below 2605_10.2100
- 3. Obtain the Dell ThinOS update package from Dell support (www.dell.com)
- 4. Follow Dell's standard ThinOS upgrade procedure to update to version 2605_10.2100 or later
