## Technical details

This vulnerability is a log injection flaw caused by improper neutralization of special elements when writing data to log files (CWE-93 or similar). An unauthorized attacker can craft input containing special characters or escape sequences that, when written to logs without proper sanitization, allow injection of arbitrary log entries or manipulation of existing log data. The attack vector is network-based, and no authentication is required. An attacker can compromise the integrity of audit logs, hide malicious activities, or forge false log entries to frame legitimate users. A fix is available in IBM Netezza Software version 11.3.1.3.
