CVSS v3.1 |
| 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 a large number of TCP connections with an invalid response instead of the final ACK (TCP-ACK). |
| The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering. |
| The Cisco Web Management interface in routers running CBOS 2.4.1 and earlier does not log invalid logins, which allows remote attackers to guess passwords without detection. |
| Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048. |
| Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.1(0) to 4.1(2), 4.5(x), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed SNMP packets. |
| The web-based configuration interface for the Cisco ATA 186 Analog Telephone Adaptor allows remote attackers to bypass authentication via an HTTP POST request with a single byte, which allows the attackers to (1) obtain the password from the login screen, or (2) reconfigure the adaptor by modifying certain request parameters. |
| In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters. |
| 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, and ONS 15600 1.x(x), allows remote attackers to cause a denial of service (control card reset) via malformed (1) TCP and (2) UDP packets. |
| 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. |
| Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords. |
| Cisco Unity 2.x, 3.x, and 4.x, when integrated with Microsoft Exchange, has several hard coded usernames and passwords, which allows remote attackers to gain unauthorized access and change configuration settings or read outgoing or incoming e-mail messages. |
| CBOS 2.4.1 and earlier in Cisco 600 routers allows remote attackers to cause a denial of service via a slow stream of TCP SYN packets. |
| The lock manager in Cisco CNS Network Registrar 6.0 through 6.1.1.3 allows remote attackers to cause a denial of service (process crash) via a certain "unexpected packet sequence." |
| Memory leak in the Call Telephony Integration (CTI) Framework authentication for Cisco CallManager 3.0 and 3.1 before 3.1(3) allows remote attackers to cause a denial of service (crash and reload) via a series of authentication failures, e.g. via incorrect passwords. |
| Cisco CNS Network Registrar Central Configuration Management (CCM) server 6.0 through 6.1.1.3 allows remote attackers to cause a denial of service (CPU consumption) by ending a connection after sending a certain sequence of packets. |
| The buffer overflow trigger in Cisco Security Agent (CSA) before 4.0.3 build 728 waits five minutes for a user response before terminating the process, which could allow remote attackers to bypass the buffer overflow protection by sending additional buffer overflow attacks within the five minute timeout period. |
| Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length. |
| Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size. |
| Memory leak in Cisco Catalyst 4000, 5000, and 6000 series switches allows remote attackers to cause a denial of service via a series of failed telnet authentication attempts. |
| Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag. |
