CVSS: 8.6EPSS: 0%CPEs: 322EXPL: 0CVE-2019-1752 – Cisco IOS and IOS XE Software ISDN Interface Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1752
A vulnerability in the ISDN functions of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of specific values in the Q.931 information elements. An attacker could exploit this vulnerability by calling the affected device with specific Q.931 information elements being present. An exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. Una vulnerabilidad en las funciones ISDN 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/107589 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-isdn • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 930EXPL: 0CVE-2019-1748 – Cisco IOS and IOS XE Software Network Plug-and-Play Agent Certificate Validation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1748
A vulnerability in the Cisco Network Plug-and-Play (PnP) agent of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data. The vulnerability exists because the affected software insufficiently validates certificates. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt and modify confidential information on user connections to the affected software. Una vulnerabilidad en el agente Cisco Network Plug-and-Play (PnP) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado obtenga acceso no autorizado a datos sensibles. • http://www.securityfocus.com/bid/107619 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-pnp-cert • CWE-295: Improper Certificate Validation •
CVSS: 8.8EPSS: 0%CPEs: 155EXPL: 0CVE-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. Una vulnerabilidad en el software Cisco IOS XE podría permitir que un atacante local autenticado inyecte comandos arbitrarios que se ejecutan con privilegios elevados. • http://www.securityfocus.com/bid/107588 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-xecmd • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
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.
