CVSS: 7.8EPSS: 0%CPEs: 38EXPL: 0CVE-2019-1726 – Cisco NX-OS Software CLI Bypass to Internal Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1726
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to access internal services that should be restricted on an affected device, such as the NX-API. The vulnerability is due to insufficient validation of arguments passed to a certain CLI command. An attacker could exploit this vulnerability by including malicious input as the argument to the affected command. A successful exploit could allow the attacker to bypass intended restrictions and access internal services of the device. An attacker would need valid device credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/108409 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-cli-bypass • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.2EPSS: 0%CPEs: 211EXPL: 0CVE-2019-1649 – Cisco Secure Boot Hardware Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2019-1649
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. • http://www.securityfocus.com/bid/108350 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot https://www.kb.cert.org/vuls/id/400865 https://www.us-cert.gov/ics/advisories/icsa-20-072-03 • CWE-284: Improper Access Control CWE-667: Improper Locking •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1618 – Cisco Nexus 9000 Series Switches Standalone NX-OS Mode Tetration Analytics Agent Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2019-1618
A vulnerability in the Tetration Analytics agent for Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an authenticated, local attacker to execute arbitrary code as root. The vulnerability is due to an incorrect permissions setting. An attacker could exploit this vulnerability by replacing valid agent files with malicious code. A successful exploit could result in the execution of code supplied by the attacker. Nexus 9000 Series Switches in Standalone NX-OS Mode are affected running versions prior to 7.0(3)I7(5). • http://www.securityfocus.com/bid/107322 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-tetra-ace • CWE-275: Permission Issues CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.4EPSS: 0%CPEs: 18EXPL: 1CVE-2019-1617 – Cisco Nexus 9000 Series Switches Standalone NX-OS Mode Fibre Channel over Ethernet NPV Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1617
A vulnerability in the Fibre Channel over Ethernet (FCoE) N-port Virtualization (NPV) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability is due to an incorrect processing of FCoE packets when the fcoe-npv feature is uninstalled. An attacker could exploit this vulnerability by sending a stream of FCoE frames from an adjacent host to an affected device. An exploit could allow the attacker to cause packet amplification to occur, resulting in the saturation of interfaces and a DoS condition. Nexus 9000 Series Switches in Standalone NX-OS Mode are affected running software versions prior to 7.0(3)I7(5) and 9.2(2). • http://www.securityfocus.com/bid/107336 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-npv-dos • CWE-913: Improper Control of Dynamically-Managed Code Resources •

https://notcve.org/view.php?id=CVE-2019-1616
A vulnerability in the Cisco Fabric Services component of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a buffer overflow, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Cisco Fabric Services packets. An attacker could exploit this vulnerability by sending a crafted Cisco Fabric Services packet to an affected device. A successful exploit could allow the attacker to cause a buffer overflow, resulting in process crashes and a DoS condition on the device. MDS 9000 Series Multilayer Switches are affected running software versions prior to 6.2(25), 8.1(1b), 8.3(1). • http://www.securityfocus.com/bid/107395 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-fabric-dos • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
