CVSS: 6.5EPSS: 0%CPEs: 57EXPL: 1CVE-2021-1385 – Cisco IOx Application Environment Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2021-1385
A vulnerability in the Cisco IOx application hosting environment of multiple Cisco platforms could allow an authenticated, remote attacker to conduct directory traversal attacks and read and write files on the underlying operating system or host system. This vulnerability occurs because the device does not properly validate URIs in IOx API requests. An attacker could exploit this vulnerability by sending a crafted API request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to read or write arbitrary files on the underlying operating system. Una vulnerabilidad en el entorno de alojamiento de aplicaciones Cisco IOx de varias plataformas Cisco, podría permitir a un atacante remoto autenticado llevar a cabo ataques de salto de directorio y leer y escribir archivos en el sistema operativo o host subyacente. • https://github.com/orangecertcc/security-research/security/advisories/GHSA-hhfw-6cm2-v3w5 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-pt-hWGcPf7g • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.4EPSS: 0%CPEs: 123EXPL: 0CVE-2021-1403 – Cisco IOS XE Software Web UI Cross-Site WebSocket Hijacking Vulnerability
https://notcve.org/view.php?id=CVE-2021-1403
A vulnerability in the web UI feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site WebSocket hijacking (CSWSH) attack and cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient HTTP protections in the web UI on an affected device. An attacker could exploit this vulnerability by persuading an authenticated user of the web UI to follow a crafted link. A successful exploit could allow the attacker to corrupt memory on the affected device, forcing it to reload and causing a DoS condition. Una vulnerabilidad en la funcionalidad de la Interfaz de Usuario Web del Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado llevar a cabo un ataque de secuestro de WebSocket (CSWSH) entre sitios y causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-cswsh-FKk9AzT5 • CWE-345: Insufficient Verification of Data Authenticity CWE-1021: Improper Restriction of Rendered UI Layers or Frames •
CVSS: 7.2EPSS: 0%CPEs: 55EXPL: 0CVE-2021-1453 – Cisco IOS XE Software for the Catalyst 9000 Family Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1453
A vulnerability in the software image verification functionality of Cisco IOS XE Software for the Cisco Catalyst 9000 Family of switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. The vulnerability is due to an improper check in the code function 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 boot a malicious software image or execute unsigned code and bypass the image verification check part of the secure boot process of an affected device. To exploit this vulnerability, the attacker would need to have unauthenticated physical access to the device or obtain privileged access to the root shell on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-cat-verify-BQ5hrXgH • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 9.8EPSS: 0%CPEs: 55EXPL: 0CVE-2021-1451 – Cisco IOS XE Software Easy Virtual Switching System Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1451
A vulnerability in the Easy Virtual Switching System (VSS) feature of Cisco IOS XE Software for Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying Linux operating system of an affected device. The vulnerability is due to incorrect boundary checks of certain values in Easy VSS protocol packets that are destined for an affected device. An attacker could exploit this vulnerability by sending crafted Easy VSS protocol packets to UDP port 5500 while the affected device is in a specific state. When the crafted packet is processed, a buffer overflow condition may occur. A successful exploit could allow the attacker to trigger a denial of service (DoS) condition or execute arbitrary code with root privileges on the underlying Linux operating system of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-evss-code-exe-8cw5VSvw • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.6EPSS: 0%CPEs: 265EXPL: 0CVE-2021-1446 – Cisco IOS XE Software DNS NAT Protocol Application Layer Gateway Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1446
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 cause an affected device to reload. The vulnerability is due to a logic error that occurs when an affected device inspects certain DNS packets. An attacker could exploit this vulnerability by sending crafted DNS packets through an affected device that is performing NAT for DNS packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability can be exploited only by traffic that is sent through an affected device via IPv4 packets. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-alg-dos-hbBS7SZE • CWE-754: Improper Check for Unusual or Exceptional Conditions •
