A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to inject and execute arbitrary commands with administrative privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of user-supplied input to the web UI. An attacker could exploit this vulnerability by submitting crafted input to the web UI. A successful exploit could allow an attacker to execute arbitrary commands with administrative privileges on an affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-web-cmdinj2-fOnjk2LD ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-web-cmdinj2-fOnjk2LD"] This advisory is part of the June 3, 2020, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes 23 Cisco Security Advisories that describe 25 vulnerabilities.

A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to inject and execute arbitrary commands with administrative privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of user-supplied input to the web UI. An attacker could exploit this vulnerability by submitting crafted input to the web UI. A successful exploit could allow an attacker to execute arbitrary commands with administrative privileges on an affected device.

The administrator graphical user interface (GUI) lacks correct handling of RBAC, which may allow a malicious user to send modified HTTP requests to the targeted device. If exploited, a read-only remote attacker could potentially execute commands or configuration changes as the administrator. Due to insufficient validation of user input, this vulnerability could allow a malicious user to inject custom input into the web user interface. If exploited, a remote attacker could potentially execute arbitrary code with administrative privileges on the operating system. A vulnerability in the DNS application layer gateway (ALG) functionality used by Network Address Translation (NAT) in Cisco IOS XE software could allow an unauthenticated, remote attacker to reload an affected device. A vulnerability in the Secure Shell (SSH) server code of Cisco IOS software and Cisco IOS XE software could allow an authenticated, remote attacker to reload an affected device. Due to improper input sanitization, this vulnerability could allow a malicious user with administrative privileges to submit specially crafted input in the web user interface. If exploited, a remote attacker could potentially execute arbitrary commands with root privileges on the operating system. Due to improper validation of user supplied input, a malicious user could potentially create a file on the target device and upload a second malicious file to the device. If exploited, a user could execute arbitrary code with root privi…
