VAR-200303-0053
Vulnerability from variot - Updated: 2025-04-03 22:19Cisco ONS15454 and ONS15327 running ONS before 3.4 have an account for the VxWorks Operating System in the TCC, TCC+ and XTC that cannot be changed or disabled, which allows remote attackers to gain privileges by connecting to the account via Telnet. Cisco ONS15454 and Cisco ONS15327 are optical fiber network platforms developed by CISCO.
Cisco ONS 15454 and Cisco ONS 15327 devices have default accounts. Remote attackers can use this vulnerability to gain unauthorized access and take complete control of the device.
TCC, TCC + and XTC contain a default username and password. This account can be used to access the VxWorks operating system, and this account cannot be changed or closed. Using this account, an attacker can remotely access through the Telnet service and take complete control of the device.
The vulnerability CISCO BUG ID is: CSCdy70756
