CVSS: 8.6EPSS: 0%CPEs: 43EXPL: 0CVE-2019-1616 – Cisco NX-OS Software Cisco Fabric Services Denial of Service Vulnerability
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 •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2019-1603 – Cisco NX-OS Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1603
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to escalate lower-level privileges to the administrator level. The vulnerability is due to insufficient authorization enforcement. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. A successful exploit could allow an attacker to make configuration changes to the system as administrator. Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4). • http://www.securityfocus.com/bid/107328 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-privesc • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2019-1604 – Cisco NX-OS Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1604
A vulnerability in the user account management interface of Cisco NX-OS Software could allow an authenticated, local attacker to gain elevated privileges on an affected device. The vulnerability is due to an incorrect authorization check of user accounts and their associated Group ID (GID). An attacker could exploit this vulnerability by taking advantage of a logic error that will permit the use of higher privileged commands than what is necessarily assigned. A successful exploit could allow an attacker to execute commands with elevated privileges on the underlying Linux shell of an affected device. Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22), 8.2(3), and 8.3(2). • http://www.securityfocus.com/bid/107323 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-privesca • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
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 •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2019-1596 – Cisco NX-OS Software Bash Shell Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1596
A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level to root. The attacker must authenticate with valid user credentials. The vulnerability is due to incorrect permissions of a system executable. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level to root. • http://www.securityfocus.com/bid/107340 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-pe • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
