A vulnerability in the Web Services Management Agent WSMA function of Cisco IOS XE Software could allow an authenticated, remote attacker to execute arbitrary Cisco IOS commands as a privilege level 15 user. The vulnerability occurs because the affected software improperly sanitizes user-supplied...

CVE-2019-1758

A vulnerability in 802.1x function of Cisco IOS Software on the Catalyst 6500 Series Switches could allow an unauthenticated, adjacent attacker to access the network prior to authentication. The vulnerability is due to how the 802.1x packets are handled in the process path. An attacker could...

CVE-2019-1756

A vulnerability in Cisco IOS XE Software could allow an authenticated, remote attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability occurs because the affected software improperly sanitizes user-supplied input. An attacker who has...

Input validation

A vulnerability in the Cluster Management Protocol CMP processing code in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to trigger a denial of service DoS condition on an affected device. The vulnerability is due to insufficient input validation wh...

CVE-2019-1750

A vulnerability in the Easy Virtual Switching System VSS of Cisco IOS XE Software on Catalyst 4500 Series Switches could allow an unauthenticated, adjacent attacker to cause the switches to reload. The vulnerability is due to incomplete error handling when processing Cisco Discovery Protocol CDP...

CVE-2019-1751

A vulnerability in the Network Address Translation 64 NAT64 functions of Cisco IOS Software could allow an unauthenticated, remote attacker to cause either an interface queue wedge or a device reload. The vulnerability is due to the incorrect handling of certain IPv4 packet streams that are sent...

CVE-2019-1740

A vulnerability in the Network-Based Application Recognition NBAR feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability are due to a parsing issue on DNS packets. An attacker could exploit...

Race condition

A vulnerability in the Network Address Translation 64 NAT64 functions of Cisco IOS Software could allow an unauthenticated, remote attacker to cause either an interface queue wedge or a device reload. The vulnerability is due to the incorrect handling of certain IPv4 packet streams that are sent...

CVE-2019-1753

A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated but unprivileged level 1, remote attacker to run privileged Cisco IOS commands by using the web UI. The vulnerability is due to a failure to validate and sanitize input in Web Services Management Agent WSMA...

Input validation

A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with elevated privileges. The vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability b...
