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: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-1145 – Cisco StarOS for Cisco ASR 5000 Series Routers Arbitrary File Read Vulnerability
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 •
CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3244 – Cisco ASR 5000 Series Aggregation Services Routers Enhanced Charging Service Rule Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3244
A vulnerability in the Enhanced Charging Service (ECS) functionality of Cisco ASR 5000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to bypass the traffic classification rules on an affected device. The vulnerability is due to insufficient input validation of user traffic going through an affected device. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to bypass the traffic classification rules and potentially avoid being charged for traffic consumption. Una vulnerabilidad en la funcionalidad Enhanced Charging Service (ECS) de Routers de Servicios de Agregación Cisco ASR 5000 Series, podría permitir a un atacante remoto no autenticado omitir las reglas de clasificación de tráfico sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asr5k-ecs-bypass-2LqfPCL • CWE-20: Improper Input Validation •
CVSS: 6.8EPSS: 0%CPEs: 4EXPL: 0CVE-2019-16026 – Cisco Mobility Management Entity Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-16026
A vulnerability in the implementation of the Stream Control Transmission Protocol (SCTP) on Cisco Mobility Management Entity (MME) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an eNodeB that is connected to an affected device. The vulnerability is due to insufficient input validation of SCTP traffic. An attacker could exploit this vulnerability by leveraging a man-in-the-middle position between the eNodeB and the MME and then sending a crafted SCTP message to the MME. A successful exploit would cause the MME to stop sending SCTP messages to the eNodeB, triggering a DoS condition. Una vulnerabilidad en la implementación del Stream Control Transmission Protocol (SCTP) en Cisco Mobility Management Entity (MME), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un eNodeB que esté conectado en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-mme-dos • CWE-20: Improper Input Validation •
