| A vulnerability in the Device Analytics action frame processing of Cisco Wireless Access Point (AP) Software could allow an unauthenticated, adjacent attacker to inject wireless 802.11 action frames with arbitrary information.
This vulnerability is due to insufficient verification checks of incoming 802.11 action frames. An attacker could exploit this vulnerability by sending 802.11 Device Analytics action frames with arbitrary parameters. A successful exploit could allow the attacker to inject Device Analytics action frames with arbitrary information, which could modify the Device Analytics data of valid wireless clients that are connected to the same wireless controller. |
| A vulnerability in the IPv6 Router Advertisement (RA) packet processing of Cisco Access Point Software could allow an unauthenticated, adjacent attacker to modify the IPv6 gateway on an affected device.
This vulnerability is due to a logic error in the processing of IPv6 RA packets that are received from wireless clients. An attacker could exploit this vulnerability by associating to a wireless network and sending a series of crafted IPv6 RA packets. A successful exploit could allow the attacker to temporarily change the IPv6 gateway of an affected device. This could also lead to intermittent packet loss for any wireless clients that are associated with the affected device. |
| A vulnerability in the API subsystem of Cisco Unified Intelligence Center could allow an authenticated, remote attacker to obtain sensitive information from an affected system.
This vulnerability is due to improper validation of requests to certain API endpoints. An attacker could exploit this vulnerability by sending a valid request to a specific API endpoint within the affected system. A successful exploit could allow a low-privileged user to view sensitive information on the affected system that should be restricted. To exploit this vulnerability, the attacker must have valid user credentials on the affected system. |
| A vulnerability in the Secure Copy Protocol (SCP) and SFTP feature of Cisco IOS XR Software could allow an authenticated, local attacker to create or overwrite files in a system directory, which could lead to a denial of service (DoS) condition. The attacker would require valid user credentials to perform this attack.
This vulnerability is due to a lack of proper validation of SCP and SFTP CLI input parameters. An attacker could exploit this vulnerability by authenticating to the device and issuing SCP or SFTP CLI commands with specific parameters. A successful exploit could allow the attacker to impact the functionality of the device, which could lead to a DoS condition. The device may need to be manually rebooted to recover.
Note: This vulnerability is exploitable only when a local user invokes SCP or SFTP commands at the Cisco IOS XR CLI. A local user with administrative privileges could exploit this vulnerability remotely. |
| A vulnerability in the boot process of Cisco Access Point (AP) Software could allow an unauthenticated, physical attacker to bypass the Cisco Secure Boot functionality and load a software image that has been tampered with on an affected device.
This vulnerability exists because unnecessary commands are available during boot time at the physical console. An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised. |
| A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition.
This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a crash of the dhcpd process. While the dhcpd process is restarting, which may take approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period and rely on the DHCPv4 server of the affected device.
Notes:
Only the dhcpd process crashes and eventually restarts automatically. The router does not reload.
This vulnerability only applies to DHCPv4. DHCP version 6 (DHCPv6) is not affected. |
| A vulnerability in the CLI of the Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. To exploit this vulnerability, the attacker must have read-only or higher privileges on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a crafted CLI command. A successful exploit could allow the attacker to elevate privileges to root. |
| A vulnerability in the access control list (ACL) processing on MPLS interfaces in the ingress direction of Cisco IOS XR Software could allow an unauthenticated, remote attacker to bypass a configured ACL.
This vulnerability is due to improper assignment of lookup keys to internal interface contexts. An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to access resources behind the affected device that were supposed to be protected by a configured ACL. |
| A vulnerability in the Layer 2 Ethernet services of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the line card network processor to reset, resulting in a denial of service (DoS) condition.
This vulnerability is due to the incorrect handling of specific Ethernet frames that are received on line cards that have the Layer 2 services feature enabled. An attacker could exploit this vulnerability by sending specific Ethernet frames through an affected device. A successful exploit could allow the attacker to cause the ingress interface network processor to reset, resulting in a loss of traffic over the interfaces that are supported by the network processor. Multiple resets of the network processor would cause the line card to reset, resulting in a DoS condition. |
| A vulnerability in the Cisco FXOS CLI feature on specific hardware platforms for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to elevate their administrative privileges to root. The attacker would need valid administrative credentials on the device to exploit this vulnerability. This vulnerability exists because certain system configurations and executable files have insecure storage and permissions. An attacker could exploit this vulnerability by authenticating on the device and then performing a series of steps that includes downloading malicious system files and accessing the Cisco FXOS CLI to configure the attack. A successful exploit could allow the attacker to obtain root access on the device. |
| A vulnerability in the access control list (ACL) programming of Cisco Nexus 3550-F Switches could allow an unauthenticated, remote attacker to send traffic that should be blocked to the management interface of an affected device.
This vulnerability exists because ACL deny rules are not properly enforced at the time of device reboot. An attacker could exploit this vulnerability by attempting to send traffic to the management interface of an affected device. A successful exploit could allow the attacker to send traffic to the management interface of the affected device. |
| A vulnerability in Cisco NX-OS Software could allow an authenticated, local attacker with privileges to access the Bash shell to execute arbitrary code as root on an affected device.
This vulnerability is due to insufficient security restrictions when executing commands from the Bash shell. An attacker with privileges to access the Bash shell could exploit this vulnerability by executing a specific crafted command on the underlying operating system. A successful exploit could allow the attacker to execute arbitrary code with the privileges of root. |
| A vulnerability in Cisco NX-OS Software could allow an authenticated, local attacker with privileges to access the Bash shell to elevate privileges to network-admin on an affected device.
This vulnerability is due to insufficient security restrictions when executing application arguments from the Bash shell. An attacker with privileges to access the Bash shell could exploit this vulnerability by executing crafted commands on the underlying operating system. A successful exploit could allow the attacker to create new users with the privileges of network-admin. |
| A vulnerability in the web-based management interface of Cisco Unified Industrial Wireless Software for Cisco Ultra-Reliable Wireless Backhaul (URWB) Access Points could allow an unauthenticated, remote attacker to perform command injection attacks with root privileges on the underlying operating system.
This vulnerability is due to improper validation of input to the web-based management interface.
