Cisco: >> Ios Xe >> 16.9.4c Security Vulnerabilities
Multiple vulnerabilities in the implementation of the Common Industrial Protocol (CIP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to insufficient input processing of CIP traffic. An attacker could exploit these vulnerabilities by sending crafted CIP traffic to be processed by an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

A vulnerability in the authorization controls for the Cisco IOx application hosting infrastructure in Cisco IOS XE Software could allow an unauthenticated, remote attacker to execute Cisco IOx API commands without proper authorization. The vulnerability is due to incorrect handling of requests for authorization tokens. An attacker could exploit this vulnerability by using a crafted API call to request such a token. An exploit could allow the attacker to obtain an authorization token and execute any of the IOx API commands on an affected device.

A vulnerability in Role Based Access Control (RBAC) functionality of Cisco IOS XE Web Management Software could allow a Read-Only authenticated, remote attacker to execute commands or configuration changes as an Admin user. The vulnerability is due to incorrect handling of RBAC for the administration GUI. An attacker could exploit this vulnerability by sending a modified HTTP request to the affected device. An exploit could allow the attacker as a Read-Only user to execute CLI commands or configuration changes as if they were an Admin user.

A vulnerability in the ROMMON of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to those of the root user of the underlying operating system. The vulnerability is due to the ROMMON allowing for special parameters to be passed to the device at initial boot up. An attacker could exploit this vulnerability by sending parameters to the device at initial boot up. An exploit could allow the attacker to elevate from a Priv15 user to the root user and execute arbitrary commands with the privileges of the root user.

A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker with administrative privileges to execute arbitrary code with root privileges on the underlying Linux shell. The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by first creating a malicious file on the affected device itself and then uploading a second malicious file to the device. A successful exploit could allow the attacker to execute arbitrary code with root privileges or bypass licensing requirements on the device.

A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, local attacker with privileged EXEC credentials to execute arbitrary code on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient input validation of data passed to the Tcl interpreter. An attacker could exploit this vulnerability by loading malicious Tcl code on an affected device. A successful exploit could allow the attacker to cause memory corruption or execute the code with root privileges on the underlying OS of the affected device.

A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.

A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier.
