VAR-200303-0048

Vulnerability from variot - Updated: 2025-04-03 22:19

Cisco ONS15454 and ONS15327 running ONS before 3.4 allows remote attackers to modify the system configuration and delete files by establishing an FTP connection to the TCC, TCC+ or XTC using a username and password that does not exist. It is possible for attackers to authenticate to FTP services on TCC, TCC+ and XTC control cards using a non-existent username/password. Unauthorized FTP access will enable an attacker to upload modified configuration files or delete software images. To exploit this issue, the attacker must be able to access the FTP services on TCC, TCC+ and XTC control cards. Cisco ONS15454 and Cisco ONS15327 are fiber optic network platforms developed by CISCO. There is a flaw in the FTP service implementation of Cisco ONS15454 and Cisco ONS15327 devices. The CISCO BUG ID of this vulnerability is: CSCds52295 < Link: http://www.cisco.com/warp/public/707/ons-multiple-vuln-pub.shtml >
