CVSS: 8.5EPSS: 0%CPEs: 61EXPL: 0CVE-2021-1443 – Cisco IOS XE Software Web UI OS Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1443
A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying operating system of an affected device. The vulnerability exists because the affected software improperly sanitizes values that are parsed from a specific configuration file. An attacker could exploit this vulnerability by tampering with a specific configuration file and then sending an API call. A successful exploit could allow the attacker to inject arbitrary code that would be executed on the underlying operating system of the affected device. To exploit this vulnerability, the attacker would need to have a privileged set of credentials to the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-os-cmd-inj-Ef6TV5e9 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.8EPSS: 0%CPEs: 224EXPL: 0CVE-2021-1442 – Cisco IOS XE Software Plug-and-Play Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1442
A vulnerability in a diagnostic command for the Plug-and-Play (PnP) subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to the level of an Administrator user (level 15) on an affected device. The vulnerability is due to insufficient protection of sensitive information. An attacker with low privileges could exploit this vulnerability by issuing the diagnostic CLI show pnp profile when a specific PnP listener is enabled on the device. A successful exploit could allow the attacker to obtain a privileged authentication token. This token can be used to send crafted PnP messages and execute privileged commands on the targeted system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-pnp-priv-esc-AmG3kuVL • CWE-532: Insertion of Sensitive Information into Log File •

https://notcve.org/view.php?id=CVE-2021-1435
A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to inject arbitrary commands that can be executed as the root user. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted request to the web UI of an affected device with arbitrary commands injected into a portion of the request. A successful exploit could allow the attacker to execute arbitrary commands as the root user.

CVSS: 7.4EPSS: 0%CPEs: 37EXPL: 0CVE-2020-3409 – Cisco IOS and IOS XE Software PROFINET Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3409
A vulnerability in the PROFINET feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to crash and reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted PROFINET packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted PROFINET packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to crash and reload, resulting in a DoS condition on the device. Una vulnerabilidad en la funcionalidad PROFINET de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se bloquee y recargue, resultando en una condición de denegación de servicio (DoS) en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-profinet-J9QMCHPB • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.2EPSS: 0%CPEs: 98EXPL: 0CVE-2020-3417 – Cisco IOS XE Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3417
A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to execute persistent code at boot time and break the chain of trust. This vulnerability is due to incorrect validations by boot scripts when specific ROM monitor (ROMMON) variables are set. An attacker could exploit this vulnerability by installing code to a specific directory in the underlying operating system (OS) and setting a specific ROMMON variable. A successful exploit could allow the attacker to execute persistent code on the underlying OS. To exploit this vulnerability, the attacker would need access to the root shell on the device or have physical access to the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xbace-OnCEbyS • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
