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-2019-1737 – Cisco IOS and IOS XE Software IP Service Level Agreement Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1737
A vulnerability in the processing of IP Service Level Agreement (SLA) packets by Cisco IOS Software and Cisco IOS XE software could allow an unauthenticated, remote attacker to cause an interface wedge and an eventual denial of service (DoS) condition on the affected device. The vulnerability is due to improper socket resources handling in the IP SLA responder application code. An attacker could exploit this vulnerability by sending crafted IP SLA packets to an affected device. An exploit could allow the attacker to cause an interface to become wedged, resulting in an eventual denial of service (DoS) condition on the affected device. Una vulnerabilidad en el procesamiento de los paquetes IP SLA (Service Level Agreement) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque una cuña (wedge) en la interfaz y, finalmente, una denegación de servicio (DoS) en el dispositivo afectado. • http://www.securityfocus.com/bid/107604 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-ipsla-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
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-2018-0197 – Cisco IOS and IOS XE Software VLAN Trunking Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0197
A vulnerability in the VLAN Trunking Protocol (VTP) subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to corrupt the internal VTP database on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to a logic error in how the affected software handles a subset of VTP packets. An attacker could exploit this vulnerability by sending VTP packets in a sequence that triggers a timeout in the VTP message processing code of the affected software. A successful exploit could allow the attacker to impact the ability to create, modify, or delete VLANs and cause a DoS condition. There are workarounds that address this vulnerability. • http://www.securityfocus.com/bid/105424 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-vtp • CWE-20: Improper Input Validation •
