CVSS: 6.9EPSS: 0%CPEs: 8EXPL: 0CVE-2020-3513 – Cisco IOS XE Software for Cisco ASR 900 Series Route Switch Processor 3 Arbitrary Code Execution Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3513
Multiple vulnerabilities in the initialization routines that are executed during bootup of Cisco IOS XE Software for Cisco ASR 900 Series Aggregation Services Routers with a Route Switch Processor 3 (RSP3) installed could allow an authenticated, local attacker with high privileges to execute persistent code at bootup and break the chain of trust. These vulnerabilities are due to incorrect validations by boot scripts when specific ROM monitor (ROMMON) variables are set. An attacker could exploit these vulnerabilities by copying a specific file to the local file system of an affected device and defining specific ROMMON variables. A successful exploit could allow the attacker to run arbitrary code on the underlying operating system (OS) with root privileges. To exploit these vulnerabilities, an attacker would need to have 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-iosxe-rsp3-rce-jVHg8Z7c • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-749: Exposed Dangerous Method or Function •
CVSS: 4.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3516 – Cisco IOS XE Software Web UI Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3516
A vulnerability in the web server authentication of Cisco IOS XE Software could allow an authenticated, remote attacker to crash the web server on the device. The vulnerability is due to insufficient input validation during authentication. An attacker could exploit this vulnerability by entering unexpected characters during a valid authentication. A successful exploit could allow the attacker to crash the web server on the device, which must be manually recovered by disabling and re-enabling the web server. Una vulnerabilidad en la autenticación del servidor web de Cisco IOS XE Software, podría permitir a un atacante remoto autenticado bloquear el servidor web en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-WEB-UI-exNFmcPO • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-3527
A vulnerability in the Polaris kernel of Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to crash the device. The vulnerability is due to insufficient packet size validation. An attacker could exploit this vulnerability by sending jumbo frames or frames larger than the configured MTU size to the management interface of this device. A successful exploit could allow the attacker to crash the device fully before an automatic recovery. Una vulnerabilidad en el kernel Polaris de Cisco Catalyst 9200 Series Switches, podría permitir a un atacante remoto no autenticado bloquear el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-JP-DOS-g5FfGm8y • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
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 •
CVSS: 8.6EPSS: 0%CPEs: 60EXPL: 0CVE-2020-3203 – Cisco IOS XE Software Catalyst 9800 Series Wireless Controllers Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3203
A vulnerability in the locally significant certificate (LSC) provisioning feature of Cisco Catalyst 9800 Series Wireless Controllers that are running Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak that could lead to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain public key infrastructure (PKI) packets. An attacker could exploit this vulnerability by sending crafted Secure Sockets Layer (SSL) packets to an affected device. A successful exploit could cause an affected device to continuously consume memory, which could result in a memory allocation failure that leads to a crash and causes a DoS condition. Una vulnerabilidad en la funcionalidad locally significant certificate (LSC) de Cisco Catalyst 9800 Series Wireless Controllers que ejecuta Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar una pérdida de memoria que podría conllevar a una condición de denegación de servicio (DoS) . • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ewlc-dos-TkuPVmZN • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
