CVE-2025-12508
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 · uneditedWhen using domain users as BRAIN2 users, communication with Active Directory services is unencrypted. This can lead to the interception of authentication data and compromise confidentiality.
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 confidenceWhen domain users are used as BRAIN2 users, the communication with Active Directory services occurs without encryption (likely cleartext LDAP). This allows network-based attackers to intercept authentication credentials (plaintext passwords or NTLM hashes), leading to confidentiality compromise and potential credential theft.

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 domain user configuration in BRAIN2Review the BRAIN2 user management settings or configuration files to determine if any users are configured with 'domain user' authentication type rather than local authentication. Look for settings relating to Active Directory integration or LDAP authentication.Affected if Domain users (Active Directory users) are configured as BRAIN2 users for authentication.
-
Check AD connection protocol settingsInspect the BRAIN2 configuration for Active Directory connection settings. Look for parameters controlling the LDAP connection type, such as 'ldap_protocol', 'use_ssl', 'use_tls', or 'authentication_method'. Compare the settings against whether they specify 'LDAPS' (port 636) or 'TLS' versus plain 'LDAP' (port 389).Affected if The AD connection is configured to use plain LDAP (port 389) without SSL/TLS enabled.
-
Verify authentication mechanism for domain usersExamine the authentication configuration or logs for domain user login attempts. Check if the authentication mechanism shows 'simple bind' or cleartext password transmission versus Kerberos or NTLM over secure channels.Affected if Authentication uses cleartext LDAP simple bind rather than Kerberos or encrypted channels.
-
Inspect network listener for LDAP trafficUse network monitoring tools (such as tcpdump, Wireshark, or netstat) to observe outbound traffic from the BRAIN2 server to AD domain controllers on ports 389 (LDAP) versus 636 (LDAPS) or 88 (Kerberos).Affected if Unencrypted LDAP traffic (port 389) is observed communicating with AD servers.
-
Review AD integration configuration filesLocate and examine configuration files related to Active Directory integration (commonly named ad_config.xml, ldap.conf, or similar). Search for entries specifying the AD server connection string and protocol scheme.Affected if The configuration specifies 'ldap://' URLs rather than 'ldaps://' for domain controller connections.
You are affected if domain users are configured as BRAIN2 users and the Active Directory connection uses unencrypted LDAP (plaintext) rather than LDAPS or Kerberos authentication.

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 dataEnable LDAPS (LDAP over SSL/TLS) or configure Kerberos authentication for Active Directory communication to encrypt all domain user authentication traffic.
