CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2020-3601 – Cisco StarOS Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3601
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. To exploit this vulnerability, an attacker would need to have valid administrative credentials on an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-staros-priv-esc-gGCUMFxv • 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: 55EXPL: 0CVE-2019-16019 – Cisco IOS XR Software BGP EVPN Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-16019
Multiple vulnerabilities in the implementation of Border Gateway Protocol (BGP) Ethernet VPN (EVPN) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerabilities are due to incorrect processing of BGP update messages that contain crafted EVPN attributes. An attacker could exploit these vulnerabilities by sending BGP EVPN update messages with malformed attributes to be processed by an affected system. A successful exploit could allow the attacker to cause the BGP process to restart unexpectedly, resulting in a DoS condition. The Cisco implementation of BGP accepts incoming BGP traffic only from explicitly defined peers. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200122-ios-xr-evpn • CWE-399: Resource Management Errors •

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 •
