CVE-2013-1519
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 Application Express component in Oracle Database Server before 4.2.1 allows remote attackers to affect integrity 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 · low confidenceVulnerability in Oracle Application Express (APEX) component of Oracle Database Server versions prior to 4.2.1 allows remote attackers to impact system integrity through unspecified means. The attack vector and exact technical weakness are not detailed in the available documentation.

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.
-
Confirm APEX is installedConnect to the Oracle Database as a DBA and query: SELECT owner, object_name FROM all_objects WHERE object_name like 'APEX%' AND object_type = 'PACKAGE' AND rownum <= 10;Affected if No APEX packages are found - the system is not affected because APEX is not installed
-
Identify APEX versionExecute: SELECT version FROM apex_release; or SELECT text FROM sys.apex_version; or SELECT version FROM apex_040200.wwv_flow_version; (adjust schema based on installation)Affected if Query returns no results or fails - unable to determine version
-
Compare installed version to CVE thresholdCheck the version returned from step 2. If it starts with a number lower than 4.2.1 (e.g., 4.0.x, 4.1.x, 4.2.0), the installed version is prior to 4.2.1 and falls within the affected rangeAffected if Version is 4.2.0 or earlier - the environment is affected because the version is prior to the fixed release 4.2.1
-
Verify APEX listener or HTTP gateway configurationCheck if APEX is accessible over HTTP/HTTPS by accessing the APEX endpoint (e.g., https://server:port/ords/). If the application is exposed, the vulnerability can be exploited remotelyAffected if APEX is accessible externally - remote attackers can potentially exploit the integrity flaw
The environment is affected if Oracle Application Express is installed and its version is prior to 4.2.1 (such as 4.2.0 or earlier), especially when the APEX listener is exposed over the network.
