CVE-2023-39439
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 · uneditedSAP Commerce Cloud may accept an empty passphrase for user ID and passphrase authentication, allowing users to log into the system without a passphrase.
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 confidenceSAP Commerce Cloud contains an authentication bypass vulnerability where the system accepts empty passphrases during user ID and passphrase authentication. This allows unauthenticated attackers to gain access to the system by providing an empty password field, effectively bypassing the authentication mechanism entirely.

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 installed SAP Commerce versionLocate the SAP Commerce installation directory and check the version manifest or configuration files (commonly found in the installer or platform properties). Alternatively, access the admin console or check the version information via SAP hAC (Hybris Administration Console).Affected if The installed version matches exactly 2211 (SAP Commerce Cloud) or 2105/2205 (SAP Commerce Hycom)
-
Confirm user ID and passphrase authentication is enabledReview the SAP Commerce authentication configuration files (such as spring security configuration or authenticator beans) to verify that the standard user ID and password authentication mechanism is active.Affected if User ID and passphrase (password) based authentication is configured and enabled in the system
-
Check authentication endpoint accessibilityIdentify the authentication endpoint used for user login (typically the /j_spring_security_check or /auth/login path). Verify the endpoint is exposed and accessible without prior authentication.Affected if The authentication endpoint is publicly accessible and accepts user credentials without additional authentication layers
-
Verify empty passphrase handling configurationExamine the password validation or authentication filter configuration in the Spring Security or authentication-related XML/JSON configuration files. Look for settings controlling minimum password length or empty password acceptance.Affected if The system allows empty passwords to be accepted or lacks proper password validation in the authentication flow
You are affected if your SAP Commerce version is exactly 2211, 2105, or 2205 AND the user ID/password authentication mechanism is enabled and accessible, particularly if empty passwords can be submitted without rejection.

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.
From vendor dataApply SAP security patches for CVE-2023-39439 immediately. Until patches are applied, disable or restrict affected authentication endpoints and implement additional layer of authentication controls.
