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
Advantech R-SeeNet versions 2.4.22 is installed with a hidden root-level user that is not available in the users list. This hidden user has a password that cannot be changed by users.

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

Advantech R-SeeNet version 2.4.22 contains a hidden root-level user account embedded in the system that is not displayed in the administrative users list and has a password that cannot be modified by administrators, effectively functioning as a backdoor that grants full root privileges to anyone aware of the credentials.

MitigationApply vendor-provided patches when available; in the interim, restrict network access to R-SeeNet systems via firewall/rules, segment the asset from sensitive networks, and monitor for unauthorized administrative access.

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 installed R-SeeNet version
    Locate the R-SeeNet installation directory and check the version information file, or access the application's About/Version page in the web interface
    Affected if version is 2.4.22 or lower
  2. Inspect system user database directly
    Access the R-SeeNet backend database or user configuration files (such as users.db, config.xml, or similar) using administrative file system access or database query tools - do not rely on the web admin UI user list
    Affected if a root-level user account exists that is not displayed or selectable in the administrative web interface
  3. Compare UI user list with backend user storage
    Export or view the complete list of users from the application's database or configuration files, then compare it against what the web administrative interface displays in the user management section
    Affected if the backend contains more users than the web interface shows, particularly any account with elevated privileges
  4. Verify hidden account privileges
    If a hidden account is discovered in step 2 or 3, confirm it has administrative or root-level permissions by examining the user role or privilege field in the backend user data
    Affected if a hidden account with administrative or root privileges is present in the system configuration

You are affected if your R-SeeNet installation is version 2.4.22 or lower AND your backend user configuration contains an administrative user account that does not appear in the web interface user list.

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.

Upgrade available Upgrade to a release after 2.4.22
Interim mitigation

Apply vendor-provided patches when available; in the interim, restrict network access to R-SeeNet systems via firewall/rules, segment the asset from sensitive networks, and monitor for unauthorized administrative access.

Recommended fix Moderate confidence

Latest R-SeeNet version beyond 2.4.22 (contact Advantech for specific fixed release)

  1. 1. Check current R-SeeNet version by accessing the application or checking system documentation
  2. 2. Contact Advantech support to obtain the latest version that addresses CVE-2023-2611
  3. 3. Before upgrading, perform a complete backup of the R-SeeNet configuration and database
  4. 4. Follow Advantech's official upgrade procedure for R-SeeNet
  5. 5. After upgrade, verify the hidden root-level user no longer exists by reviewing user lists
  6. 6. Change all administrator passwords and any default credentials as a security best practice
  7. 7. Verify the application is functioning correctly after the upgrade
