CVE-2012-0519
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 · uneditedUnspecified vulnerability in the Core RDBMS component in Oracle Database Server 11.2.0.2, when running on Windows, allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors.
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 confidenceVulnerability in Oracle Database Server 11.2.0.2 Core RDBMS component on Windows platform allows remote authenticated users to impact confidentiality, integrity, and availability through unspecified vectors. This is a database-level flaw requiring authenticated database access.

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 Oracle Database Server versionConnect to the database using SQL*Plus or any Oracle client and execute: SELECT VERSION FROM V$INSTANCE; or check the Oracle inventory for installed database versions.Affected if The version returned is exactly 11.2.0.2
-
Confirm Windows platformCheck the operating system where the Oracle Database is installed by running 'systeminfo' on the database server or checking OS properties.Affected if The database server is running on Windows OS
-
Verify database network accessibilityCheck if the Oracle Listener (TNS Listener) is running and configured to accept remote connections. Review listener.ora and check listener status with 'lsnrctl status'.Affected if The database listener is accessible over the network (not bound to localhost only)
-
Assess authentication exposureReview which database users have privileges to connect remotely and check if external authentication methods (like OS authentication) are enabled. Query SELECT * FROM V$PARAMETER WHERE NAME LIKE 'remote_os_authent';Affected if Remote authentication is enabled and the database accepts remote user connections
A system is affected if it runs Oracle Database Server version 11.2.0.2 on Windows with network-accessible database authentication enabled, allowing remote authenticated users to connect.

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 Oracle Critical Patch Update (CPU) containing the fix for CVE-2012-0519. If immediate patching is not feasible, restrict network access to the database server and limit database user privileges to reduce attack surface.
