CVE-2002-1641
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 · uneditedMultiple buffer overflows in Oracle Web Cache for Oracle 9i Application Server (9iAS) allow remote attackers to execute arbitrary code 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.

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.
-
Locate Oracle Application Server Web Cache installationCheck for Oracle home directories (common paths: /opt/oracle, /u01/oracle, /orahome, or C:\oracle on Windows). Look for subdirectory 'webcache' within the Oracle Application Server installation tree. Also check ORACLE_HOME environment variable.Affected if Oracle Application Server with Web Cache component is not found in the environment (not affected).
-
Identify Web Cache versionWithin the webcache directory, look for a VERSION file, or run 'webcache version' command if available. On Windows, check Add/Remove Programs for 'Oracle9i Application Server Web Cache' entry and its version.Affected if Version cannot be determined or differs from the installed version display.
-
Compare installed version to affected versionsVerify if the installed version matches exactly: 2.0.0.0, 2.0.0.1, 2.0.0.2, or 2.0.0.3. These are exact version matches, not ranges.Affected if Installed version is one of: 2.0.0.0, 2.0.0.1, 2.0.0.2, or 2.0.0.3.
-
Confirm Web Cache service is running and exposedCheck if the Web Cache HTTP ports (typically 7777, 7778, or 8080) are listening. Use 'netstat -an' or 'lsof -i' to list active network listeners. Verify the service is accessible from network.Affected if Web Cache is running and accessible on network ports.
The system is affected only if Oracle Application Server Web Cache version 2.0.0.0, 2.0.0.1, 2.0.0.2, or 2.0.0.3 is installed and the Web Cache component is active and network-accessible.

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 updates for Oracle 9iAS or migrate to a supported Oracle product version; if patching is not feasible, isolate the affected system from untrusted networks.
