CVE-2013-3751
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 XML Parser component in Oracle Database Server 11.2.0.2, 11.2.0.3, and 12.1.0.1 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 confidenceUnspecified vulnerability in the XML Parser component of Oracle Database Server versions 11.2.0.2, 11.2.0.3, and 12.1.0.1 allows remote authenticated users to execute arbitrary code or cause denial of service via crafted XML input, potentially compromising confidentiality, integrity, and availability of the database.

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 versionQuery V$VERSION or execute: SELECT VERSION FROM V$INSTANCE; to obtain the installed Oracle Database Server version number.Affected if Version is 11.2.0.2 or 11.2.0.3 exactly.
-
Confirm XML Parser component presenceQuery DBA_REGISTRY or execute: SELECT COMP_NAME, VERSION, STATUS FROM DBA_REGISTRY WHERE COMP_NAME LIKE '%XML%'; to check if XML Parser component is installed and its status.Affected if XML Parser component shows as INSTALLED and VALID in the database.
-
Verify database network accessibilityCheck if Oracle Listener is running and exposed to network: execute lsnrctl status LISTENER or check listener.ora configuration for non-localhost binding.Affected if Database listener is accessible from remote network addresses, not bound to 127.0.0.1 only.
-
Confirm authenticated user access existsReview existing database user accounts with CONNECT privilege or verify that external authentication (LDAP, Kerberos) is configured for remote access.Affected if Remote authenticated user accounts exist or can be created, enabling remote XML input submission.
Environment is affected if running Oracle Database Server exactly version 11.2.0.2 or 11.2.0.3 with the XML Parser component installed, the database is network-accessible, and remote authenticated users can submit XML input.

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.
dbcve · scopedApply Oracle Critical Patch Update (CPU) released in July 2013 or subsequent relevant patches. If patching is not immediately feasible, restrict network access to database listeners and limit XML parser functionality to trusted sources.
Oracle Database 19c or 21c/23c (supported versions with this vulnerability resolved)
- 1. Identify the current Oracle Database 11g R2 patch level by querying SELECT * FROM v$version;
- 2. Download and apply the latest Oracle Critical Patch Update (CPU) for Oracle Database 11.2.0.x from Oracle Support (support.oracle.com), or
- 3. Plan an upgrade to a supported Oracle Database version such as 19c or 21c/23c for a more durable solution
- 4. Before upgrading, run the Oracle Pre-Upgrade Information Tool (preupgrade.jar) to identify required pre-upgrade actions
- 5. Perform a full backup of the database using RMAN or your preferred backup method
- 6. Apply the upgrade following Oracle's official upgrade documentation for your target version
- 7. After upgrade, verify the XML Parser component is functioning correctly and re-run security scans
