CVSS: 6.7EPSS: 0%CPEs: 47EXPL: 0CVE-2019-1615 – Cisco NX-OS Software Image Signature Verification Vulnerability
https://notcve.org/view.php?id=CVE-2019-1615
A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability is due to improper verification of digital signatures for software images. An attacker could exploit this vulnerability by loading an unsigned software image on an affected device. A successful exploit could allow the attacker to boot a malicious software image. Note: The fix for this vulnerability requires a BIOS upgrade as part of the software upgrade. • http://www.securityfocus.com/bid/107397 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-sig-verif • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1591 – Cisco Nexus 9000 Series Fabric Switches Application Centric Infrastructure Mode Shell Escape Vulnerability
https://notcve.org/view.php?id=CVE-2019-1591
A vulnerability in a specific CLI command implementation of Cisco Nexus 9000 Series ACI Mode Switch Software could allow an authenticated, local attacker to escape a restricted shell on an affected device. The vulnerability is due to insufficient sanitization of user-supplied input when issuing a specific CLI command with parameters on an affected device. An attacker could exploit this vulnerability by authenticating to the device CLI and issuing certain commands. A successful exploit could allow the attacker to escape the restricted shell and execute arbitrary commands with root-level privileges on the affected device. This vulnerability only affects Cisco Nexus 9000 Series ACI Mode Switches that are running a release prior to 14.0(3d). • http://www.securityfocus.com/bid/107311 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-shell-escape • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 20EXPL: 0CVE-2019-1593 – Cisco NX-OS Software Bash Shell Role-Based Access Control Bypass Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1593
A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. 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 by executing commands that should be restricted to other roles. • http://www.securityfocus.com/bid/107324 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nx-os-bash-escal • CWE-264: Permissions, Privileges, and Access Controls •
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 •

https://notcve.org/view.php?id=CVE-2019-1588
A vulnerability in the Cisco Nexus 9000 Series Fabric Switches running in Application-Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to read arbitrary files on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms of user-supplied input sent to an affected device. A successful exploit could allow the attacker unauthorized access to read arbitrary files on an affected device. This vulnerability has been fixed in version 14.0(1h). Una vulnerabilidad en Cisco Nexus 9000 Series Fabric Switches que se ejecuta en el modo Application-Centric Infrastructure (ACI) podría permitir a un atacante local autenticado leer archivos arbitrarios en un dispositivo afectado. • http://www.securityfocus.com/bid/107316 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-file-read • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •
