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 •

https://notcve.org/view.php?id=CVE-2021-1145
A vulnerability in the Secure FTP (SFTP) of Cisco StarOS for Cisco ASR 5000 Series Routers could allow an authenticated, remote attacker to read arbitrary files on an affected device. To exploit this vulnerability, the attacker would need to have valid credentials on the affected device. The vulnerability is due to insecure handling of symbolic links. An attacker could exploit this vulnerability by sending a crafted SFTP command to an affected device. A successful exploit could allow the attacker to read arbitrary files on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-staros-file-read-L3RDvtey • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •

https://notcve.org/view.php?id=CVE-2020-3602
A vulnerability in the CLI of Cisco StarOS operating system for Cisco ASR 5000 Series Routers could allow an authenticated, local attacker to elevate privileges on an affected device. The vulnerability is due to insufficient input validation of CLI commands. An attacker could exploit this vulnerability by sending crafted commands to the CLI. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the root user on the affected device. To exploit this vulnerability, an attacker would need to have valid credentials on an affected device and know the password for the cli test-commands command. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-staros-privilege-esc-pyb7YTd • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

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 •
