HighSummary
CVE-2002-1553 affects Cisco ONS15454 and ONS15327 devices running ONS versions prior to 3.4. It allows remote attackers to modify system configuration and delete files by establishing an FTP connection to TCC, TCC+, or XTC using a non-existent username and password.
Risk Assessment
Attackers can make unauthorized changes to system configuration and delete critical files, potentially leading to significant disruptions in network infrastructure operations.
Recommendation
It is recommended to upgrade the software to version 3.4 or later and implement appropriate security measures to restrict access to FTP interfaces.
