CVSS: 5.9EPSS: 0%CPEs: 239EXPL: 0CVE-2019-1757 – Cisco IOS and IOS XE Software Smart Call Home Certificate Validation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1757
A vulnerability in the Cisco Smart Call Home feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. 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 confidential information on user connections to the affected software. Una vulnerabilidad en la funcionalidad Cisco Smart Call Home de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado obtenga acceso de lectura no autorizado a datos sensibles mediante un certificado inválido. • http://www.securityfocus.com/bid/107617 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-call-home-cert • CWE-295: Improper Certificate Validation •
CVSS: 4.7EPSS: 0%CPEs: 72EXPL: 0CVE-2019-1758 – Cisco IOS Software Catalyst 6500 Series 802.1x Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1758
A vulnerability in 802.1x function of Cisco IOS Software on the Catalyst 6500 Series Switches could allow an unauthenticated, adjacent attacker to access the network prior to authentication. The vulnerability is due to how the 802.1x packets are handled in the process path. An attacker could exploit this vulnerability by attempting to connect to the network on an 802.1x configured port. A successful exploit could allow the attacker to intermittently obtain access to the network. Una vulnerabilidad en la función 802.1x del software Cisco IOS en los switches Catalyst 6500 Series podría permitir que un atacante adyacente sin autenticar acceda a la red antes de autenticarse. • http://www.securityfocus.com/bid/107616 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-c6500 • CWE-287: Improper Authentication •
CVSS: 9.0EPSS: 0%CPEs: 16EXPL: 0CVE-2019-1756 – Cisco IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1756
A vulnerability in Cisco IOS XE Software could allow an authenticated, remote attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability occurs because the affected software improperly sanitizes user-supplied input. An attacker who has valid administrator access to an affected device could exploit this vulnerability by supplying a username with a malicious payload in the web UI and subsequently making a request to a specific endpoint in the web UI. A successful exploit could allow the attacker to run arbitrary commands as the root user, allowing complete compromise of the system. Una vulnerabilidad en el software Cisco IOS XE podría permitir que un atacante remoto autenticado ejecute comandos en el shell de Linux subyacente de un dispositivo afectado con privilegios root. • http://www.securityfocus.com/bid/107598 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-iosxe-cmdinject • CWE-20: Improper Input Validation •
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 •

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 •
