CVE-2008-1815
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 Change Data Capture component in Oracle Database 10.1.0.5, 10.2.0.3, and 11.1.0.6 has unknown impact and remote authenticated attack vectors related to DBMS_CDC_UTILITY, aka DB02. NOTE: the previous information was obtained from the April 2008 CPU. Oracle has not commented on reliable researcher claims that DB02 is for SQL injection in LOCK_CHANGE_SET.
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 confidenceOracle Database vulnerability in the Change Data Capture (CDC) component's DBMS_CDC_UTILITY package. The vulnerability, identified as DB02 from the April 2008 Critical Patch Update, is associated with SQL injection in the LOCK_CHANGE_SET function. It requires remote authenticated access and has medium severity impact affecting confidentiality and availability.

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.
-
Determine Oracle Database versionConnect to the database as a privileged user (e.g., SYS or SYSTEM) and run: SELECT VERSION FROM PRODUCT_COMPONENT_VERSION WHERE PRODUCT LIKE 'Oracle%'; or check the banner from SELECT * FROM V$VERSION;Affected if The installed version is 10.1.0.5, 10.2.0.3, or 11.1.0.6
-
Verify Change Data Capture (CDC) is installedQuery DBA_OBJECTS for the DBMS_CDC_UTILITY package: SELECT owner, object_name, object_type FROM DBA_OBJECTS WHERE object_name = 'DBMS_CDC_UTILITY' AND object_type = 'PACKAGE';Affected if The package exists in the database (indicating CDC component is installed)
-
Confirm DBMS_CCDC_UTILITY.LOCK_CHANGE_SET function existsQuery DBA_OBJECTS for the LOCK_CHANGE_SET function: SELECT owner, object_name, object_type FROM DBA_OBJECTS WHERE object_name = 'LOCK_CHANGE_SET' AND object_type = 'FUNCTION';Affected if The LOCK_CHANGE_SET function exists and is accessible to the user
-
Check if CDC change sets exist in the databaseQuery USER_CHANGE_SETS or DBA_CHANGE_SETS (depending on privileges) to see if any change sets are defined: SELECT change_set_name, creation_time FROM USER_CHANGE_SETS;Affected if Any change sets are created, as the vulnerability exploits the LOCK_CHANGE_SET function on existing change sets
You are affected if your Oracle Database version is 10.1.0.5, 10.2.0.3, or 11.1.0.6 AND the DBMS_CDC_UTILITY package with its LOCK_CHANGE_SET function exists in your database.

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) April 2008 or later, which includes the fix for DB02 in DBMS_CDC_UTILITY. Alternatively, upgrade to a patched Oracle Database version beyond 11.1.0.6.
