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
In SAP Commerce Cloud - versions HY_COM 1905, HY_COM 2005, HY_COM2105, HY_COM 2011, HY_COM 2205, COM_CLOUD 2211, a locked B2B user can misuse the forgotten password functionality to un-block his user account again and re-gain access if SAP Commerce Cloud - Composable Storefront is used as storefront, due to weak access controls in place. This leads to a considerable impact on confidentiality and integrity.

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 · high confidence

In SAP Commerce Cloud Composable Storefront, a locked B2B user can exploit the forgotten password functionality to unlock their account and regain unauthorized access due to weak access controls that improperly conflate password reset with account unlock mechanisms.

MitigationApply SAP security patches for this vulnerability and implement proper separation between password reset and account unlock functionality to prevent locked users from self-unlocking.

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 SAP Commerce Cloud Composable Storefront installation
    Check your installed packages or deployment manifests for 'SAP Commerce Cloud' with the 'Composable Storefront' component
    Affected if The product is SAP Commerce Cloud Composable Storefront
  2. Verify the exact version is 8.1
    Run 'npm list @sap/spartacus-components' or check your package-lock.json/version file for the Composable Storefront version
    Affected if The installed version is exactly 8.1 (not higher or lower)
  3. Confirm B2B functionality is enabled
    Check your app configuration for 'b2b' module or feature flag enabled (look for 'spartacus.features.b2b' or similar in your config)
    Affected if B2B features are enabled in the storefront configuration
  4. Check if forgotten password feature is accessible
    Navigate to the login page and locate the 'Forgot Password?' link, or inspect the /forgottenpassword endpoint in your routing configuration
    Affected if The forgotten password functionality is accessible and operational
  5. Verify account lockout policy exists
    Review user account security settings in the SAP Admin Console or back-end under 'Account Lockout' or 'Password Policy' settings
    Affected if Account lockout is configured (meaning locked users could exploit the password reset to unlock)
  6. Test password reset for a locked B2B account
    Create a test B2B user, lock the account via failed login attempts, then attempt the forgotten password flow to see if the account unlocks without admin intervention
    Affected if The password reset process also unlocks the account (vulnerable behavior)

You are affected if you run SAP Commerce Cloud Composable Storefront version 8.1 with B2B features enabled, where the forgotten password flow permits locked users to unlock their accounts without administrator action.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply SAP security patches for this vulnerability and implement proper separation between password reset and account unlock functionality to prevent locked users from self-unlocking.

Recommended fix Moderate confidence

Apply the SAP Security Note for CVE-2023-42481 and upgrade to the latest supported SAP Commerce Cloud release (COM_CLOUD 2211 or higher)

  1. Check the official SAP Security Note for CVE-2023-42481 at support.sap.com to obtain the specific patch and apply it
  2. Ensure SAP Commerce Cloud is updated to a version beyond those listed as affected (HY_COM 1905, HY_COM 2005, HY_COM2105, HY_COM 2011, HY_COM 2205, COM_CLOUD 2211)
  3. If immediate patching is not possible, disable the forgotten password functionality for B2B users in the Composable Storefront configuration as a temporary mitigation
  4. Review and enforce stricter access controls on password reset workflows in the storefront configuration
  5. After applying the patch, verify that locked B2B users can no longer self-unlock through the forgotten password feature
Caveat Test thoroughly in a non-production environment as custom storefront extensions may be affected by the access control changes
