A vulnerability in the REST API of Cisco UCS Director could allow an authenticated, remote attacker with administrative privileges to obtain confidential information from an affected device. The vulnerability exists because confidential information is returned as part of an API response. An attacker could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to obtain the API key of another user, which would allow the attacker to impersonate the account of that user on the affected device. To exploit this vulnerability, the attacker must have administrative privileges on the device.Show less

Multiple vulnerabilities in Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an unauthenticated, remote attacker or an authenticated, local attacker to execute arbitrary code on an affected system or cause an affected system to crash and reload. For more information about these vulnerabilities, see the Details section of this advisory.Show less

Multiple vulnerabilities in the Cisco IOx application environment of Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) that are running Cisco IOS Software could allow an attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.Show less

A vulnerability in the Cisco Application Framework component of the Cisco IOx application environment could allow an authenticated, remote attacker to write or modify arbitrary files in the virtual instance that is running on the affected device. The vulnerability is due to insufficient input validation of user-supplied application packages. An attacker who can upload a malicious package within Cisco IOx could exploit the vulnerability to modify arbitrary files. The impacts of a successful exploit are limited to the scope of the virtual instance and do not affect the device that is hosting Cisco IOx.Show less

A vulnerability in the Cisco Application Framework component of the Cisco IOx application environment could allow an authenticated, local attacker to overwrite arbitrary files in the virtual instance that is running on the affected device. The vulnerability is due to insufficient path restriction enforcement. An attacker could exploit this vulnerability by including a crafted file in an application package. An exploit could allow the attacker to overwrite files.Show less

A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS Software and Cisco IOS XE Software on Catalyst 4500 Series Switches could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient input validation when the software processes specific SNMP object identifiers. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: To exploit this vulnerability by using SNMPv2c or earlier, the attacker must know the SNMP read-only community string for an affected system. To exploit this vulnerability by using SNMPv3, the attacker must know the user credentials for the affected system.Show less

A vulnerability in the virtual console authentication of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an authenticated but low-privileged, local attacker to log in to the Virtual Device Server (VDS) of an affected device by using a set of default credentials. The vulnerability is due to the presence of weak, hard-coded credentials. An attacker could exploit this vulnerability by authenticating to the targeted device and then connecting to VDS through the device’s virtual console by using the static credentials. A successful exploit could allow the attacker to access the Linux shell of VDS as the root user.Show less

A vulnerability in the web-based Local Manager interface of the Cisco IOx Application Framework could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based Local Manager interface of an affected device.
