| The encryption library in Cisco IOS Software 15.2(1)T, 15.2(1)T1, and 15.2(2)T, Cisco NX-OS in Cisco MDS 9222i Multiservice Modular Switch, Cisco MDS 9000 18/4-Port Multiservice Module, and Cisco MDS 9000 Storage Services Node module before 5.2(6), and Cisco IOS in Cisco VPN Services Port Adaptor for Catalyst 6500 12.2(33)SXI, and 12.2(33)SXJ when IP Security (aka IPSec) is used, allows remote attackers to obtain unencrypted packets from encrypted sessions. |
| Cisco IOS 12.0 through 15.6, Adaptive Security Appliance (ASA) Software 7.0.1 through 9.7.1.2, NX-OS 4.0 through 12.0, and IOS XE 3.6 through 3.18 are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated, remote attacker to take full control of the OSPF Autonomous System (AS) domain routing table, allowing the attacker to intercept or black-hole traffic. The attacker could exploit this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause the targeted router to flush its routing table and propagate the crafted OSPF LSA type 1 update throughout the OSPF AS domain. To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. This vulnerability can only be triggered by sending crafted unicast or multicast OSPF LSA type 1 packets. No other LSA type packets can trigger this vulnerability. OSPFv3 is not affected by this vulnerability. Fabric Shortest Path First (FSPF) protocol is not affected by this vulnerability. Cisco Bug IDs: CSCva74756, CSCve47393, CSCve47401. |
| A vulnerability in the Fibre Channel over Ethernet (FCoE) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when an FCoE-related process unexpectedly reloads. This vulnerability affects Cisco NX-OS Software on the following Cisco devices when they are configured for FCoE: Multilayer Director Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches. More Information: CSCvc91729. Known Affected Releases: 8.3(0)CV(0.833). Known Fixed Releases: 8.3(0)ISH(0.62) 8.3(0)CV(0.944) 8.1(1) 8.1(0.8)S0 7.3(2)D1(0.47). |
| A vulnerability in the CLI of Cisco NX-OS System Software 7.1 through 7.3 running on Cisco Nexus Series Switches could allow an authenticated, local attacker to perform a command injection attack. The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting crafted command arguments into a vulnerable CLI command. An exploit could allow the attacker to read or write arbitrary files at the user's privilege level outside of the user's path. Cisco Bug IDs: CSCvb86787, CSCve60516, CSCve60555. |
| A vulnerability in the authentication, authorization, and accounting (AAA) implementation of Cisco Firepower Extensible Operating System (FXOS) and NX-OS System Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability occurs because AAA processes prevent the NX-OS System Manager from receiving keepalive messages when an affected device receives a high rate of login attempts, such as in a brute-force login attack. System memory can run low on the FXOS devices under the same conditions, which could cause the AAA process to unexpectedly restart or cause the device to reload. An attacker could exploit this vulnerability by performing a brute-force login attack against a device that is configured with AAA security services. A successful exploit could allow the attacker to cause the affected device to reload. This vulnerability affects the following Cisco products if they are running Cisco FXOS or NX-OS System Software that is configured for AAA services: Firepower 4100 Series Next-Generation Firewall, Firepower 9300 Security Appliance, Multilayer Director Switches, Nexus 1000V Series Switches, Nexus 1100 Series Cloud Services Platforms, Nexus 2000 Series Switches, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches in NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules, Unified Computing System (UCS) 6100 Series Fabric Interconnects, UCS 6200 Series Fabric Interconnects, UCS 6300 Series Fabric Interconnects. Cisco Bug IDs: CSCuq58760, CSCuq71257, CSCur97432, CSCus05214, CSCux54898, CSCvc33141, CSCvd36971, CSCve03660. |
| A vulnerability in the Telnet CLI command of Cisco NX-OS System Software 7.1 through 7.3 running on Cisco Nexus Series Switches could allow an authenticated, local attacker to perform a command injection attack. The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting crafted command arguments into the Telnet CLI command. An exploit could allow the attacker to read or write arbitrary files at the user's privilege level outside of the user's path. Cisco Bug IDs: CSCvb86771. |

| A vulnerability in the Open Agent Container (OAC) feature of Cisco Nexus Series Switches could allow an unauthenticated, local attacker to read and send packets outside the scope of the OAC. The vulnerability is due to insufficient internal security measures in the OAC feature. An attacker could exploit this vulnerability by crafting specific packets for communication on the device-internal network. A successful exploit could allow the attacker to run code on the underlying host operating system. OAC is not enabled by default. For a device to be vulnerable, an administrator would need to install and activate this feature. This vulnerability affects the following Cisco Nexus Series Switches: Nexus 2000 Series Fabric Extenders, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches. Cisco Bug IDs: CSCve53542, CSCvf36621. |
| A vulnerability in the guest shell feature of Cisco NX-OS System Software could allow an authenticated, local attacker to read and send packets outside the scope of the guest shell container. An attacker would need valid administrator credentials to perform this attack. The vulnerability is due to insufficient internal security measures in the guest shell feature. An attacker could exploit this vulnerability by sending or receiving packets on the device-internal network outside of the guest shell container, aka "Unauthorized Internal Interface Access." This vulnerability affects the following products running Cisco NX-OS System Software: Nexus 3000 Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules. Cisco Bug IDs: CSCvf33038. |
| A Denial of Service vulnerability in the remote login functionality for Cisco NX-OS Software running on Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to cause a process used for login to terminate unexpectedly and the login attempt to fail.
