CVSS: 5.3EPSS: 0%CPEs: 228EXPL: 0CVE-2020-3496 – Cisco Small Business Smart and Managed Switches Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3496
A vulnerability in the IPv6 packet processing engine of Cisco Small Business Smart and 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 insufficient validation of incoming IPv6 traffic. An attacker could exploit this vulnerability by sending a crafted IPv6 packet through an affected device. A successful exploit could allow the attacker to cause the switch management CLI to stop responding, resulting in a DoS condition. This vulnerability is specific to IPv6 traffic. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sbss-ipv6-dos-tsgqbffW • CWE-20: Improper Input Validation •

CVSS: 10.0EPSS: 0%CPEs: 236EXPL: 0CVE-2020-3297 – Cisco Small Business Smart and Managed Switches Session Management Vulnerability
https://notcve.org/view.php?id=CVE-2020-3297
A vulnerability in session management for the web-based interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to defeat authentication protections and gain unauthorized access to the management interface. The attacker could obtain the privileges of the highjacked session account, which could include administrator privileges on the device. The vulnerability is due to the use of weak entropy generation for session identifier values. An attacker could exploit this vulnerability to determine a current session identifier through brute force and reuse that session identifier to take over an ongoing session. In this way, an attacker could take actions within the management interface with privileges up to the level of the administrative user. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sbswitch-session-JZAS5jnY • CWE-287: Improper Authentication •
CVSS: 6.1EPSS: 0%CPEs: 92EXPL: 0CVE-2020-3121 – Cisco Small Business Smart and Managed Switches Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2020-3121
A vulnerability in the web-based management interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link and access a specific page. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Small Business Smart and Managed Switches, podría permitir a un atacante remoto no autenticado llevar a cabo un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200122-sbsms-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
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 •
