CVSS: 8.6EPSS: 0%CPEs: 5EXPL: 0CVE-2021-1353 – Cisco StarOS IPv4 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1353
A vulnerability in the IPv4 protocol handling of Cisco StarOS could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory leak that occurs during packet processing. An attacker could exploit this vulnerability by sending a series of crafted IPv4 packets through an affected device. A successful exploit could allow the attacker to exhaust the available memory and cause an unexpected restart of the npusim process, leading to a DoS condition on the affected device. Una vulnerabilidad en el manejo del protocolo IPv4 de Cisco StarOS, podría permitir a un atacante no autenticado remoto causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asr-mem-leak-dos-MTWGHKk3 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 8.6EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3500 – Cisco StarOS IPv6 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3500
A vulnerability in the IPv6 implementation of Cisco StarOS 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 to an affected device with the goal of reaching the vulnerable section of the input buffer. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. This vulnerability is specific to IPv6 traffic. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asr5k-ipv6-dos-ce3zhF8m • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
