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
Unspecified vulnerability in the Core RDBMS component in Oracle Database 9.0.1.5, 9.2.0.8, 10.1.0.5, and 10.2.0.2 on Windows allows remote attackers to have an unknown impact, aka DB01. NOTE: as of 20070424, Oracle has not disputed reliable claims that this issue occurs because the NTLM SSPI AcceptSecurityContext function grants privileges based on the username provided even though all users are authenticated as Guest, which allows remote attackers to gain privileges.

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

This is a Windows-specific NTLM authentication vulnerability in older Oracle Database versions (9i and 10g). The NTLM SSPI AcceptSecurityContext function incorrectly grants database privileges based on the username provided during authentication, even though all users are actually authenticated as Guest. This allows remote attackers to bypass authentication and gain elevated privileges by supplying a privileged username.

MitigationUpgrade to a supported Oracle Database version that has this vulnerability patched, or apply the relevant Oracle Critical Patch Update. Consider disabling NTLM authentication and using stronger authentication mechanisms like Kerberos if possible.

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 the operating system
    Run 'ver' command on Windows or check system properties to confirm the platform
    Affected if The server is running any version of Microsoft Windows and hosts the vulnerable Oracle Database
  2. Check Oracle Database version
    Connect to the database as SYSDBA and run: SELECT VERSION FROM V$INSTANCE; or check the Oracle inventory for installed version
    Affected if The installed Oracle Database version is exactly 9.0.1.5, 9.2.0.8, 10.1.0.5, or 10.2.0.2
  3. Verify NTLM authentication is in use
    Check Oracle network configuration files (sqlnet.ora, listener.ora) for NTLM authentication settings, or review Oracle authentication adapter configuration
    Affected if NTLM authentication is configured or enabled as the authentication mechanism for Oracle connections

A user is affected if running Oracle Database versions 9.0.1.5, 9.2.0.8, 10.1.0.5, or 10.2.0.2 on Windows with NTLM authentication enabled.
