CVSS: 8.8EPSS: 0%CPEs: 31EXPL: 0CVE-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 •
CVSS: 8.6EPSS: 0%CPEs: 149EXPL: 0CVE-2019-1740 – Cisco IOS and IOS XE Software Network-Based Application Recognition Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1740
A vulnerability in the Network-Based Application Recognition (NBAR) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability are due to a parsing issue on DNS packets. An attacker could exploit this vulnerability by sending crafted DNS packets through routers that are running an affected version and have NBAR enabled. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la funcionalidad NBAR (Network-Based Application Recognition) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque que el dispositivo afectado se recargue. • http://www.securityfocus.com/bid/107597 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-nbar • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 14EXPL: 0CVE-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 •
CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0477 – Cisco IOS XE Software Command Injection Vulnerabilities
https://notcve.org/view.php?id=CVE-2018-0477
A vulnerability in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability exist because the affected software improperly sanitizes command arguments, failing to prevent access to certain internal data structures on an affected device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit these vulnerabilities on the device by executing CLI commands that contain custom arguments. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device. Una vulnerabilidad en el analizador CLI de Cisco IOS XE Software podría permitir que un atacante local autenticado ejecute comandos en el shell Linux subyacente de un dispositivo afectado con privilegios root. • http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-iosxe-cmdinj • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.5EPSS: 0%CPEs: 1195EXPL: 0CVE-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 •
