CVSS: 6.7EPSS: 0%CPEs: 45EXPL: 0CVE-2019-1600 – Cisco FXOS and NX-OS Software Unauthorized Directory Access Vulnerability
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 •
CVSS: 7.2EPSS: 0%CPEs: 55EXPL: 0CVE-2017-12301
https://notcve.org/view.php?id=CVE-2017-12301
A vulnerability in the Python scripting subsystem of Cisco NX-OS Software could allow an authenticated, local attacker to escape the Python parser and gain unauthorized access to the underlying operating system of the device. The vulnerability exists due to insufficient sanitization of user-supplied parameters that are passed to certain Python functions within the scripting sandbox of the affected device. An attacker could exploit this vulnerability to escape the scripting sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user. To exploit this vulnerability, an attacker must have local access and be authenticated to the targeted device with administrative or Python execution privileges. These requirements could limit the possibility of a successful exploit. • http://www.securitytracker.com/id/1039622 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171018-ppe • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 67EXPL: 0CVE-2017-3883
https://notcve.org/view.php?id=CVE-2017-3883
A vulnerability in the authentication, authorization, and accounting (AAA) implementation of Cisco Firepower Extensible Operating System (FXOS) and NX-OS System Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability occurs because AAA processes prevent the NX-OS System Manager from receiving keepalive messages when an affected device receives a high rate of login attempts, such as in a brute-force login attack. System memory can run low on the FXOS devices under the same conditions, which could cause the AAA process to unexpectedly restart or cause the device to reload. An attacker could exploit this vulnerability by performing a brute-force login attack against a device that is configured with AAA security services. A successful exploit could allow the attacker to cause the affected device to reload. • http://www.securityfocus.com/bid/101493 http://www.securitytracker.com/id/1039614 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbst03846en_us https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171018-aaavty • CWE-770: Allocation of Resources Without Limits or Throttling •
