CVSS: 7.5EPSS: 0%CPEs: 114EXPL: 0CVE-2019-1891 – Cisco Small Business Series Switches HTTP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1891
A vulnerability in the web interface of Cisco Small Business 200, 300, and 500 Series Managed Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of requests sent to the web interface. An attacker could exploit this vulnerability by sending a malicious request to the web interface of an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition. Una vulnerabilidad en la interfaz web de los Switches Administrados de las series 200, 300 y 500 de Cisco Small Business, podría permitir a un atacante remoto no identificado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-sbss-dos • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2019-1892
A vulnerability in the Secure Sockets Layer (SSL) input packet processor of Cisco Small Business 200, 300, and 500 Series Managed Switches could allow an unauthenticated, remote attacker to cause a memory corruption on an affected device. The vulnerability is due to improper validation of HTTPS packets. An attacker could exploit this vulnerability by sending a malformed HTTPS packet to the management web interface of the affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el procesador de paquetes de entrada de Secure Sockets Layer (SSL) de los Switches Administrados de las series 200, 300 y 500 de Cisco Small Business, podría permitir a un atacante remoto no autenticado causar una corrupción de memoria de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-sbss-memcorrupt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.7EPSS: 0%CPEs: 210EXPL: 0CVE-2019-1806 – Cisco Small Business Series Switches Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1806
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco Small Business Sx200, Sx300, Sx500, ESW2 Series Managed Switches and Small Business Sx250, Sx350, Sx550 Series Switches could allow an authenticated, remote attacker to cause the SNMP application of an affected device to cease processing traffic, resulting in the CPU utilization reaching one hundred percent. Manual intervention may be required before a device resumes normal operations. The vulnerability is due to improper validation of SNMP protocol data units (PDUs) in SNMP packets. An attacker could exploit this vulnerability by sending a malicious SNMP packet to an affected device. A successful exploit could allow the attacker to cause the device to cease forwarding traffic, which could result in a denial of service (DoS) condition. • http://www.securityfocus.com/bid/108335 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-sb-snmpdos • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2018-0407
A vulnerability in the web-based management interface of Cisco Small Business 300 Series (Sx300) Managed Switches could allow an authenticated, remote attacker to conduct a persistent cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.
