Security readout for executives and security teams
CVE-2002-0857 is an old Oracle Listener Control issue where malicious text in listener.ora could trigger memory corruption and code execution when lsnrctl processes it. The business risk is highest for organizations still running legacy Oracle 7.3.4, 8.1, 9.0, or 9.2 tooling. Exposure is most likely in legacy Oracle database environments where old lsnrctl versions remain installed and process listener.ora files influenced by untrusted users or remote administration paths. Prioritize this if legacy Oracle systems remain in production or administrative tooling is still used. The vulnerability is old, but arbitrary code execution against DBA systems can affect privileged database operations and sensitive data. Mitigation focus: Check Oracle Security Alert 40 and vendor support guidance for fixed versions.; Inventory Oracle 7.3.4, 8.1, 9.0, and 9.2 listener tooling.; Restrict write access to listener.ora and related network admin directories..
