Description:
Multiple vulnerabilities have been reported in various products running Cisco ONS, which can be exploited by malicious people to gain knowledge of system information, cause a DoS (Denial of Service), or gain unauthorised access.
1) The TFTP service (port 69/UDP) accepts by default "GET" and "PUT" commands without any prior user authentication. This can be exploited to gain knowledge of information in ONS system files or crash the device by uploading corrupted ONS system files.
2) An error in the network management applications' connection handling can be exploited to cause a control card to reboot. This can be achieved by not sending the final ACK packet when establishing a connection to port 1080/TCP but instead sending an invalid response.
3) Superusers can by default gain a VxWorks shell by logging in via the Telnet service even though their account has been locked out, disabled, or suspended.
