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
Buffer overflow in Oracle iSQL*Plus web application of the Oracle 9 database server allows remote attackers to execute arbitrary code via a long USERID parameter in the isqlplus URL.

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 · high confidence

Buffer overflow vulnerability in Oracle iSQL*Plus web application allows remote attackers to execute arbitrary code by submitting an excessively long USERID parameter in the isqlplus URL. The application fails to properly bounds-check user input before copying it into a fixed-size buffer.

MitigationApply Oracle security patches for the affected Oracle 9i version; if patches are unavailable for this legacy version, consider upgrading to a supported Oracle release or implementing network-level filtering to restrict access to the iSQL*Plus interface.

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. Confirm iSQL*Plus web interface is running
    Check if the iSQL*Plus HTTP service is listening by examining running services or attempting to access the iSQL*Plus URL (typically port 7778 or 5560)
    Affected if iSQL*Plus web interface is accessible and responding to requests
  2. Identify Oracle database version
    Connect to the database and run: SELECT * FROM v$VERSION; or check the Oracle installation directory for version files
    Affected if The installed version matches any of: 9.0, 9.0.1, 9.0.1.2, 9.0.1.3, 9.0.2, release_2_9.2.1, or release_2_9.2.2
  3. Verify iSQL*Plus component is installed
    Check for the presence of the iSQL*Plus application files in the Oracle home directory, typically under $ORACLE_HOME/oc4j or check the Oracle Management Server for iSQL*Plus components
    Affected if iSQL*Plus is installed and available as a web application
  4. Confirm network exposure of iSQL*Plus
    Review firewall rules or network configuration to determine if the iSQL*Plus HTTP port (default 7778) is exposed to untrusted networks
    Affected if The iSQL*Plus interface is reachable from network segments outside the trusted database administration zone

The environment is affected if Oracle9i versions 9.0.x, 9.0.1.x, 9.0.2, or 9.2.1.x through 9.2.2.x are installed with the iSQL*Plus web interface exposed on the network.
