CVSS: 5.5EPSS: 0%CPEs: 106EXPL: 0CVE-2019-1734 – Cisco FXOS and NX-OS Software Sensitive File Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-1734
A vulnerability in the implementation of a CLI diagnostic command in Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to view sensitive system files that should be restricted. The attacker could use this information to conduct additional reconnaissance attacks. The vulnerability is due to incomplete role-based access control (RBAC) verification. An attacker could exploit this vulnerability by authenticating to the device and issuing a specific CLI diagnostic command with crafted user-input parameters. An exploit could allow the attacker to perform an arbitrary read of a file on the device, and the file may contain sensitive information. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-fxos-info • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-1966 – Cisco Unified Computing System Fabric Interconnect root Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1966
A vulnerability in a specific CLI command within the local management (local-mgmt) context for Cisco UCS Fabric Interconnect Software could allow an authenticated, local attacker to gain elevated privileges as the root user on an affected device. The vulnerability is due to extraneous subcommand options present for a specific CLI command within the local-mgmt context. An attacker could exploit this vulnerability by authenticating to an affected device, entering the local-mgmt context, and issuing a specific CLI command and submitting user input. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device. The attacker would need to have valid user credentials for the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-ucs-privescalation • CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 8.8EPSS: 0%CPEs: 26EXPL: 0CVE-2019-1901 – Cisco Nexus 9000 Series ACI Mode Switch Software Link Layer Discovery Protocol Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2019-1901
A vulnerability in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an adjacent, unauthenticated attacker to cause a denial of service (DoS) condition or execute arbitrary code with root privileges. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to the targeted device. A successful exploit may lead to a buffer overflow condition that could either cause a DoS condition or allow the attacker to execute arbitrary code with root privileges. Note: This vulnerability cannot be exploited by transit traffic through the device; the crafted packet must be targeted to a directly connected interface. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190731-nxos-bo • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 65EXPL: 0CVE-2019-1768 – Cisco NX-OS Software Buffer Overflow and Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1768
A vulnerability in the implementation of a specific CLI command for Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to cause a buffer overflow condition or perform command injection. This could allow the attacker to execute arbitrary commands with elevated privileges on the underlying operating system of an affected device. 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 of the affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. • http://www.securityfocus.com/bid/108386 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-overflow-inj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.6EPSS: 0%CPEs: 205EXPL: 0CVE-2019-1858 – Cisco FXOS and NX-OS Software Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1858
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the SNMP application to leak system memory, which could cause an affected device to restart unexpectedly. The vulnerability is due to improper error handling when processing inbound SNMP packets. An attacker could exploit this vulnerability by sending multiple crafted SNMP packets to an affected device. A successful exploit could allow the attacker to cause the SNMP application to leak system memory because of an improperly handled error condition during packet processing. Over time, this memory leak could cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. • http://www.securityfocus.com/bid/108358 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-snmp-dos • CWE-20: Improper Input Validation CWE-755: Improper Handling of Exceptional Conditions •
