CVE-2019-1745 – Cisco IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1745
A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with elevated privileges. The vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected commands. An exploit could allow the attacker to gain root privileges on the affected device.

CVE-2019-1743 – Cisco IOS XE Software Arbitrary File Upload Vulnerability
https://notcve.org/view.php?id=CVE-2019-1743
A vulnerability in the web UI framework of Cisco IOS XE Software could allow an authenticated, remote attacker to make unauthorized changes to the filesystem of the affected device. The vulnerability is due to improper input validation. An attacker could exploit this vulnerability by crafting a malicious file and uploading it to the device. An exploit could allow the attacker to gain elevated privileges on the affected device. Una vulnerabilidad en el framework de la interfaz web del software Cisco IOS XE podría permitir que un atacante remoto autenticado realice cambios no autorizados en el sistema de archivos del dispositivo afectado. • http://www.securityfocus.com/bid/107591 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-afu • CWE-20: Improper Input Validation •
CVE-2019-1741 – Cisco IOS XE Software Encrypted Traffic Analytics Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1741
A vulnerability in the Cisco Encrypted Traffic Analytics (ETA) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to a logic error that exists when handling a malformed incoming packet, leading to access to an internal data structure after it has been freed. An attacker could exploit this vulnerability by sending crafted, malformed IP packets to an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition. Una vulnerabilidad en la característica ETA (Cisco Encrypted Traffic Analytics) del software Cisco IOS XE podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS). • http://www.securityfocus.com/bid/107614 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-eta-dos • CWE-20: Improper Input Validation CWE-416: Use After Free •
CVE-2018-15377 – Cisco IOS and IOS XE Software Plug and Play Agent Memory Leak Vulnerability
https://notcve.org/view.php?id=CVE-2018-15377
A vulnerability in the Cisco Network Plug and Play agent, also referred to as the Cisco Open Plug-n-Play agent, of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to insufficient input validation by the affected software. An attacker could exploit this vulnerability by sending invalid data to the Cisco Network Plug and Play agent on an affected device. A successful exploit could allow the attacker to cause a memory leak on the affected device, which could cause the device to reload. Una vulnerabilidad en el agente Cisco Network Plug and Play también llamado agente Cisco Open Plug-n-Play, de Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante remoto no autenticado provoque una fuga de memoria en un dispositivo afectado. • https://ics-cert.us-cert.gov/advisories/ICSA-19-094-02 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-pnp-memleak • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2018-0173 – Cisco IOS and IOS XE Software Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2018-0173
A vulnerability in the Cisco IOS Software and Cisco IOS XE Software function that restores encapsulated option 82 information in DHCP Version 4 (DHCPv4) packets could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a Relay Reply denial of service (DoS) condition. The vulnerability exists because the affected software performs incomplete input validation of encapsulated option 82 information that it receives in DHCPOFFER messages from DHCPv4 servers. An attacker could exploit this vulnerability by sending a crafted DHCPv4 packet to an affected device, which the device would then forward to a DHCPv4 server. When the affected software processes the option 82 information that is encapsulated in the response from the server, an error could occur. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. • http://www.securityfocus.com/bid/103545 http://www.securitytracker.com/id/1040591 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-04 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-05 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-dhcpr2 https://www.tenable.com/security/research/tra-2018-06 • CWE-20: Improper Input Validation •
