CVE-2006-0262
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 Net Foundation Layer component of Oracle Database server 8.1.7.4, 9.0.1.5, 9.0.1.5 FIPS, 9.2.0.6, and 10.1.0.4 has unspecified impact and attack vectors, as identified by Oracle Vuln# DB08.
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 Oracle Database's Net Foundation Layer (Oracle Net Services) affecting versions 8.1.7.4 through 10.1.0.4. The CVSS score of 10 indicates a network-exploitable flaw with complete impact ( confidentiality, integrity, and availability). The Net Foundation Layer handles database network communications, suggesting the flaw could allow remote attackers to compromise the database server.

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 installed Oracle Database versionConnect to the database as SYSDBA and execute: SELECT VERSION FROM V$INSTANCE; or check the ORACLE_HOME/oratab fileAffected if The version returned matches 8.1.7.4, 9.0.1.5, 9.0.1.5_fips, 9.2.0.6, or 10.1.0.4
-
Verify Oracle Net Services (Listener) is runningExecute: lsnrctl status (from ORACLE_HOME/bin) or check for listener process: ps -ef | grep tnslsnrAffected if The listener process is active and accepting network connections
-
Check listener configuration for network exposureExamine listener.ora file in ORACLE_HOME/network/admin/ and check the LISTENER and/or LOCAL_LISTENER configuration sectionsAffected if The listener is configured with ADDRESS entries accepting connections on public or untrusted network interfaces (0.0.0.0 or HOST = 0.0.0.0)
-
Confirm Oracle Net protocol is enabledReview the SQLNET.ORA file in ORACLE_HOME/network/admin/ for authentication and encryption settingsAffected if SQLNET.AUTHENTICATION_SERVICES or other Oracle Net parameters are configured, indicating the Net Foundation Layer is active
A system is affected if it runs any of the listed Oracle versions (8.1.7.4 through 10.1.0.4) with Oracle Net Services listener exposed to network accessible hosts.

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 dataThese end-of-life Oracle versions (8i, 9i, 10g) receive no security updates. Apply Oracle's quarterly security patches if on a supported version, or migrate to a currently supported Oracle Database release (19c or higher). Restrict network exposure of Oracle Net listener to trusted networks.
