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 · unedited
Dell ThinOS 10 versions prior to ThinOS 2602_10.0573, contain an Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

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 confidence

Dell ThinOS 10 versions prior to ThinOS 2602_10.0573 contain a command injection vulnerability due to improper neutralization of special elements. A low-privileged attacker with local access can inject arbitrary commands, potentially achieving elevation of privileges.

MitigationUpgrade Dell ThinOS to version 2602_10.0573 or later to remediate the command injection vulnerability. Prior to deployment, validate firmware compatibility in a test environment.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed ThinOS version
    Access ThinOS system information through the admin web interface or local console. Locate the firmware or OS version displayed in the system settings or about section.
    Affected if The version shown is 2602.x.x.x but lower than 2602.10.0573 (for example, 2602.10.0550 or 2602.5.1234). Versions starting at 2602 and below 2602.10.0573 are vulnerable.
  2. Confirm the version format matches the affected range
    Verify that the version number begins with 2602 and compare the full version string against 2602_10.0573. ThinOS versions follow a naming convention of major version (2602), followed by a dot and a build number.
    Affected if The installed version is 2602 or higher but less than 2602_10.0573 (or 2602.10.0573). Versions 2602_10.0573 and later are NOT affected.
  3. Determine if local access to the ThinOS client is possible
    Check whether physical console access, local SSH, or other local authentication mechanisms are enabled on the ThinOS system. Review access control settings in the ThinOS admin configuration.
    Affected if Local access (physical console, local user accounts, or local management interfaces) is available to low-privileged users, allowing them to reach the vulnerable input point.
  4. Identify if command input interfaces are accessible
    Locate any user-accessible fields or interfaces in ThinOS that accept system commands, network configuration inputs, or script parameters. These are typically found in administration panels, diagnostic tools, or network settings.
    Affected if A low-privileged user can reach any input field or interface where the system processes user-supplied values without proper sanitization, enabling command injection.

Your environment is affected if the installed Dell ThinOS version is 2602 or newer but older than 2602_10.0573 AND low-privileged local users can access input mechanisms on the system.

Upgrade available Upgrade to 2602.10.0573 or later
Fixed in 2602.10.0573
Interim mitigation

Upgrade Dell ThinOS to version 2602_10.0573 or later to remediate the command injection vulnerability. Prior to deployment, validate firmware compatibility in a test environment.

Recommended fix Moderate confidence

ThinOS 2602_10.0573 or later

  1. Identify the current ThinOS version by accessing the ThinOS administration interface or checking system information
  2. Confirm the version is >= 2602 and < 2602.10.0573, which indicates vulnerability to CVE-2026-23862
  3. Obtain the fixed ThinOS 2602_10.0573 or later version from Dell's official support portal at www.dell.com
  4. Follow Dell's standard ThinOS upgrade procedure, which typically involves uploading the new firmware through the ThinOS administration console
  5. Verify the upgrade was successful by confirming the new version number matches 2602.10.0573 or later
  6. Test that normal ThinOS operations function correctly post-upgrade
