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.

https://notcve.org/view.php?id=CVE-2019-16009
A vulnerability in the web UI of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or reload an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-ios-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 7.7EPSS: 0%CPEs: 155EXPL: 0CVE-2020-3235 – Cisco IOS and IOS XE Software Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3235
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS Software and Cisco IOS XE Software on Catalyst 4500 Series Switches could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient input validation when the software processes specific SNMP object identifiers. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: To exploit this vulnerability by using SNMPv2c or earlier, the attacker must know the SNMP read-only community string for an affected system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snmp-dos-USxSyTk5 https://www.oracle.com/security-alerts/cpuoct2020.html • CWE-20: Improper Input Validation CWE-118: Incorrect Access of Indexable Resource ('Range Error') •
