CVSS: 7.8EPSS: 0%CPEs: 44EXPL: 0CVE-2019-1601 – Cisco NX-OS Software Unauthorized Filesystem Access Vulnerability
https://notcve.org/view.php?id=CVE-2019-1601
A vulnerability in the filesystem permissions of Cisco NX-OS Software could allow an authenticated, local attacker to gain read and write access to a critical configuration file. The vulnerability is due to a failure to impose strict filesystem permissions on the targeted device. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow an attacker to use the content of this configuration file to bypass authentication and log in as any user of the device. MDS 9000 Series Multilayer Switches are affected in versions prior to 6.2(25), 8.1(1b), and 8.3(1). • http://www.securityfocus.com/bid/107404 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-file-access • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 8.6EPSS: 0%CPEs: 55EXPL: 0CVE-2019-1599 – Cisco NX-OS Software Netstack Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1599
A vulnerability in the network stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to an issue with allocating and freeing memory buffers in the network stack. An attacker could exploit this vulnerability by sending crafted TCP streams to an affected device in a sustained way. A successful exploit could cause the network stack of an affected device to run out of available buffers, impairing operations of control plane and management plane protocols, resulting in a DoS condition. Note: This vulnerability can be triggered only by traffic that is destined to an affected device and cannot be exploited using traffic that transits an affected device. • http://www.securityfocus.com/bid/107342 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-netstack • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2019-1600
A vulnerability in the file system permissions of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to access sensitive information that is stored in the file system of an affected system. The vulnerability is due to improper implementation of file system permissions. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow the attacker to access sensitive and critical files. Firepower 4100 Series Next-Generation Firewalls are affected in versions prior to 2.2.2.91 and 2.3.1.110. • http://www.securityfocus.com/bid/107399 http://www.securityfocus.com/bid/107404 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-directory • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.4EPSS: 0%CPEs: 31EXPL: 0CVE-2019-1594 – Cisco NX-OS Software 802.1X Extensible Authentication Protocol over LAN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1594
A vulnerability in the 802.1X implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete input validation of Extensible Authentication Protocol over LAN (EAPOL) frames. An attacker could exploit this vulnerability by sending a crafted EAPOL frame to an interface on the targeted device. A successful exploit could allow the attacker to cause the Layer 2 (L2) forwarding process to restart multiple times, leading to a system-level restart of the device and a DoS condition. Note: This vulnerability affects only NX-OS devices configured with 802.1X functionality. • http://www.securityfocus.com/bid/107325 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nx-os-lan-auth • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.4EPSS: 0%CPEs: 3EXPL: 0CVE-2019-1595 – Cisco Nexus 5600 and 6000 Series Switches Fibre Channel over Ethernet Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1595
A vulnerability in the Fibre Channel over Ethernet (FCoE) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an incorrect allocation of an internal interface index. An adjacent attacker with the ability to submit a crafted FCoE packet that crosses affected interfaces could trigger this vulnerability. A successful exploit could allow the attacker to cause a packet loop and high throughput on the affected interfaces, resulting in a DoS condition. This vulnerability has been fixed in version 7.3(5)N1(1). • http://www.securityfocus.com/bid/107320 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nexus-fbr-dos • CWE-913: Improper Control of Dynamically-Managed Code Resources •
