CVSS: 7.2EPSS: 0%CPEs: 33EXPL: 0CVE-2019-1727 – Cisco NX-OS Software Python Parser Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1727
A vulnerability in the Python scripting subsystem of Cisco NX-OS Software could allow an authenticated, local attacker to escape the Python parser and issue arbitrary commands to elevate the attacker's privilege level. The vulnerability is due to insufficient sanitization of user-supplied parameters that are passed to certain Python functions in the scripting sandbox of the affected device. An attacker could exploit this vulnerability to escape the scripting sandbox and execute arbitrary commands to elevate the attacker's privilege level. To exploit this vulnerability, the 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.securityfocus.com/bid/108341 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-pyth-escal • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.2EPSS: 0%CPEs: 50EXPL: 0CVE-2019-1728 – Cisco FXOS and NX-OS Software Secure Configuration Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1728
A vulnerability in the Secure Configuration Validation functionality of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to run arbitrary commands at system boot time with the privileges of root. The vulnerability is due to a lack of proper validation of system files when the persistent configuration information is read from the file system. An attacker could exploit this vulnerability by authenticating to the device and overwriting the persistent configuration storage with malicious executable files. An exploit could allow the attacker to run arbitrary commands at system startup and those commands will run as the root user. The attacker must have valid administrative credentials for the device. • http://www.securityfocus.com/bid/108391 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-conf-bypass • CWE-347: Improper Verification of Cryptographic Signature •
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: 6.5EPSS: 0%CPEs: 100EXPL: 0CVE-2019-1690 – Cisco Application Policy Infrastructure Controller IPv6 Link-Local Address Vulnerability
https://notcve.org/view.php?id=CVE-2019-1690
A vulnerability in the management interface of Cisco Application Policy Infrastructure Controller (APIC) software could allow an unauthenticated, adjacent attacker to gain unauthorized access on an affected device. The vulnerability is due to a lack of proper access control mechanisms for IPv6 link-local connectivity imposed on the management interface of an affected device. An attacker on the same physical network could exploit this vulnerability by attempting to connect to the IPv6 link-local address on the affected device. A successful exploit could allow the attacker to bypass default access control restrictions on an affected device. Cisco Application Policy Infrastructure Controller (APIC) devices running versions prior to 4.2(0.21c) are affected. • http://www.securityfocus.com/bid/107317 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-apic-ipv6 • CWE-284: Improper Access Control •
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 •
