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
A valid XCC user's local account permissions overrides their active directory permissions under specific configurations. This could lead to a privilege escalation. To be vulnerable, LDAP must be configured for authentication/authorization and logins configured as “Local First, then LDAP”.

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

In XCC with LDAP authentication/authorization configured and login mode set to 'Local First, then LDAP', local user account permissions incorrectly override Active Directory permissions, allowing a local account to gain higher privileges than intended through Active Directory groups.

MitigationReconfigure XCC authentication to use LDAP-only mode or ensure local account permissions do not override AD permissions in mixed authentication configurations.

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. Check XCC firmware version
    Access the Lenovo XClarity Controller web interface or use IPMI command 'ipmitool -I lanplus -H <xcc_ip> -U <user> raw ...' to retrieve firmware version. For Thinkagile Hx5530, Hx7530, Vx3331, Hx1331 compare to < 2.93_afbt30p. For Thinkagile Hx Enclosure, Hx1021 compare to < 3.72_tei388s. For Thinkagile Hx1320, Hx1321 compare to < 8.88_cdi3a4a.
    Affected if The installed firmware version is lower than the affected version for your specific model.
  2. Verify LDAP authentication is configured
    In XCC web interface, navigate to Security > Authentication/Authorization or use XCC CLI to check if LDAP/Active Directory settings are present and enabled.
    Affected if LDAP or Active Directory authentication is configured in XCC.
  3. Check login mode setting
    In XCC web interface, go to Security > User Security > Login Settings or similar authentication settings page. Identify the authentication mode dropdown which typically shows options like 'LDAP Only', 'Local First, then LDAP', 'Local Only', etc.
    Affected if The login/authentication mode is set to 'Local First, then LDAP' (sometimes labeled as 'Mixed' or 'Local then LDAP').
  4. Check for local user accounts
    In XCC web interface, navigate to User Accounts or Local Users section. Review the list of locally defined users alongside LDAP users.
    Affected if Local user accounts exist in addition to LDAP/AD authentication configuration.

Your environment is affected if XCC firmware is below the affected version for your Thinkagile model, LDAP authentication is configured, the login mode is set to 'Local First, then LDAP', and local user accounts are present, allowing local permissions to incorrectly override AD group permissions.

Reconfigure XCC authentication to use LDAP-only mode or ensure local account permissions do not override AD permissions in mixed authentication configurations.

Recommended fix High confidence

Firmware version 2.93_afbt30p (or later) for Hx5530/Hx7530/Vx3331/Hx1331; version 3.72_tei388s (or later) for Hx Enclosure/Hx1021; version 8.88_cdi3a4a (or later) for Hx1320/Hx1321

  1. 1. Identify the Thinkagile model and current firmware version using the XCC web interface or CLI.
  2. 2. Navigate to Lenovo support portal (support.lenovo.com) and locate the firmware download page for your specific Thinkagile model.
  3. 3. Download the firmware version 2.93_afbt30p or later for Hx5530, Hx7530, Vx3331, or Hx1331 models.
  4. 4. Download firmware version 3.72_tei388s or later for Hx Enclosure or Hx1021 models.
  5. 5. Download firmware version 8.88_cdi3a4a or later for Hx1320 or Hx1321 models.
  6. 6. Upload the firmware to the XCC (Xclarity Controller) via the firmware update function in the web interface or using the Lenovo XCC Utility.
  7. 7. Apply the firmware update and allow the system to reboot into the new firmware.
  8. 8. After reboot, verify the new firmware version is installed correctly.
Caveat Firmware updates may require downtime; ensure proper backup and maintenance window planning
