CVSS: 8.1EPSS: 0%CPEs: 418EXPL: 0CVE-2021-34739 – Cisco Small Business Series Switches Session Credentials Replay Vulnerability
https://notcve.org/view.php?id=CVE-2021-34739
A vulnerability in the web-based management interface of multiple Cisco Small Business Series Switches could allow an unauthenticated, remote attacker to replay valid user session credentials and gain unauthorized access to the web-based management interface of an affected device. This vulnerability is due to insufficient expiration of session credentials. An attacker could exploit this vulnerability by conducting a man-in-the-middle attack against an affected device to intercept valid session credentials and then replaying the intercepted credentials toward the same device at a later time. A successful exploit could allow the attacker to access the web-based management interface with administrator privileges. Una vulnerabilidad en la interfaz de administración basada en web de varios switches Cisco Small Business Series podría permitir a un atacante remoto no autenticado reproducir credenciales de sesión de usuario válidas y conseguir acceso no autorizado a la interfaz de administración basada en web de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-smb-switches-tokens-UzwpR4e5 • CWE-613: Insufficient Session Expiration •
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 •
