CVSS: 7.2EPSS: 0%CPEs: 314EXPL: 0CVE-2020-3209 – Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3209
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. Una vulnerabilidad en la verificación de la imagen del software en Cisco IOS XE Software, podría permitir a un atacante físico no autenticado instalar y arrancar una imagen de software malicioso o ejecutar archivos binarios sin firmar sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-digsig-bypass-FYQ3bmVq • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.2EPSS: 0%CPEs: 74EXPL: 0CVE-2020-3207 – Cisco IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3207
A vulnerability in the processing of boot options of specific Cisco IOS XE Software switches could allow an authenticated, local attacker with root shell access to the underlying operating system (OS) to conduct a command injection attack during device boot. This vulnerability is due to insufficient input validation checks while processing boot options. An attacker could exploit this vulnerability by modifying device boot options to execute attacker-provided code. A successful exploit may allow an attacker to bypass the Secure Boot process and execute malicious code on an affected device with root-level privileges. Una vulnerabilidad en el procesamiento de las opciones de arranque de los switches específicos de Cisco IOS XE Software, podría permitir a un atacante local autenticado con acceso de shell root al sistema operativo (SO) subyacente llevar a cabo un ataque de inyección de comando durante el arranque del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ngwc-cmdinj-KEwWVWR • 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: 7.2EPSS: 0%CPEs: 1283EXPL: 0CVE-2020-3204 – Cisco IOS and IOS XE Software Tcl Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3204
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. Una vulnerabilidad en el Tool Command Language (Tcl) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante local autenticado con credenciales EXEC privilegiadas ejecutar código arbitrario en el sistema operativo (SO) subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-tcl-ace-C9KuVKmm • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-3201
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 cause a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient input validation of data passed to the Tcl interpreter. An attacker could exploit this vulnerability by executing crafted Tcl arguments on an affected device. An exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en el intérprete Tool Command Language (Tcl) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante local autenticado con credenciales EXEC privilegiadas causar una condición de denegación de servicio (DoS) en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-tcl-dos-MAZQUnMF • CWE-20: Improper Input Validation •
CVSS: 5.8EPSS: 0%CPEs: 23EXPL: 0CVE-2020-3315 – Multiple Cisco Products Snort HTTP Detection Engine File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3315
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass the configured file policies on an affected system. The vulnerability is due to errors in how the Snort detection engine handles specific HTTP responses. An attacker could exploit this vulnerability by sending crafted HTTP packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured file policies and deliver a malicious payload to the protected network. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección Snort que podría permitir a un atacante remoto no autenticado omitir las políticas de archivos configuradas sobre un sistema afectado. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort_filepolbypass-m4X5DgOP https://www.debian.org/security/2023/dsa-5354 • CWE-668: Exposure of Resource to Wrong Sphere CWE-693: Protection Mechanism Failure •
