Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.6(0) and 4.6(1), 4.5(x), 4.1(0) to 4.1(3), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed (1) IP or (2) ICMP packets.CVE-2004-0714ciscoios+1EPSS score2.55%
Cisco Internetwork Operating System (IOS) 12.0S through 12.3T attempts to process SNMP solicited operations on improper ports (UDP 162 and a randomly chosen UDP port), which allows remote attackers to cause a denial of service (device reload and memory corruption).CVE-2004-0306ciscooptical_networking_systems_softwareEPSS score2.12%
Cisco ONS 15327 before 4.1(3), ONS 15454 before 4.6(1), ONS 15454 SD before 4.1(3), and Cisco ONS 15600 before 1.3(0) enable TFTP service on UDP port 69 by default, which allows remote attackers to GET or PUT ONS system files on the current active TCC in the /flash0 or /flash1 directories.CVE-2004-0307ciscooptical_networking_systems_softwareEPSS score1.63%
Cisco ONS 15327 before 4.1(3), ONS 15454 before 4.6(1), and ONS 15454 SD before 4.1(3) allows remote attackers to cause a denial of service (reset) by not sending the ACK portion of the TCP three-way handshake and sending an invalid response instead.CVE-2004-0308ciscooptical_networking_systems_softwareEPSS score1.75%
Unknown vulnerability in Cisco ONS 15327 before 4.1(3), ONS 15454 before 4.6(1), ONS 15454 SD before 4.1(3), and Cisco ONS15600 before 1.3(0) allows a superuser whose account is locked out, disabled, or suspended to gain unauthorized access via a Telnet connection to the VxWorks shell.CVE-2002-1558ciscooptical_networking_systems_softwareEPSS score2.79%
Cisco 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.CVE-2002-1556ciscooptical_networking_systems_softwareEPSS score1.39%
Cisco ONS15454 and ONS15327 running ONS before 3.4 allows attackers to cause a denial of service (reset) via an HTTP request to the TCC, TCC+ or XTC, in which the request contains an invalid CORBA Interoperable Object Reference (IOR).CVE-2002-1553ciscooptical_networking_systems_softwareEPSS score1.61%
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.CVE-2002-1554ciscooptical_networking_systems_softwareEPSS score0.36%
Cisco ONS15454 and ONS15327 running ONS before 3.4 stores usernames and passwords in cleartext in the image database for the TCC, TCC+ or XTC, which could allow attackers to gain privileges by obtaining the passwords from the image database or a backup.CVE-2002-1555ciscooptical_networking_systems_softwareEPSS score1.64%
Cisco ONS15454 and ONS15327 running ONS before 3.4 uses a "public" SNMP community string that cannot be changed, which allows remote attackers to obtain sensitive information.CVE-2002-1557ciscooptical_networking_systems_softwareEPSS score1.39%

Cisco ONS15454 optical transport platform running ONS 3.1.0 to 3.2.0 allows remote attackers to cause a denial of service (reset) by sending IP packets with non-zero Type of Service (TOS) bits to the Timing Control Card (TCC) LAN interface.CVE-2006-1670ciscooptical_networking_systems_softwareEPSS score2.30%
Control cards for Cisco Optical Networking System (ONS) 15000 series nodes before 20060405 allow remote attackers to cause a denial of service (memory exhaustion and possibly card reset) by sending an invalid response when the final ACK is expected, aka bug ID CSCei45910.CVE-2006-1672ciscoons_15310-cl_series+3EPSS score4.12%
The installation of Cisco Transport Controller (CTC) for Cisco Optical Networking System (ONS) 15000 series nodes adds a Java policy file entry with a wildcard that grants the java.security.AllPermission permission to any http URL containing "fs/LAUNCHER.jar", which allows remote attackers to execute arbitrary code on a CTC workstation, aka bug ID CSCea25049.CVE-2006-1671ciscoons_15310-cl_series+3EPSS score2.44%
Control cards for Cisco Optical Networking System (ONS) 15000 series nodes before 20060405 allow remote attackers to cause a denial of service (card reset) via (1) a "crafted" IP packet to a device with secure mode EMS-to-network-element access, aka bug ID CSCsc51390; (2) a "crafted" IP packet to a device with IP on the LAN interface, aka bug ID CSCsd04168; and (3) a "malformed" OSPF packet, aka bug ID CSCsc54558.
