CVSS: 8.4EPSS: 0%CPEs: 34EXPL: 0CVE-2019-1950 – Cisco IOS XE SD-WAN Software Default Credentials Vulnerability
https://notcve.org/view.php?id=CVE-2019-1950
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-cred-EVGSF259 • CWE-255: Credentials Management Errors CWE-1188: Initialization of a Resource with an Insecure Default •

A memory leak vulnerability exists in Cisco IOS before 15.2(1)T due to a memory leak in the HTTP PROXY Server process (aka CSCtu52820), when configured with Cisco ISR Web Security with Cisco ScanSafe and User Authenticaiton NTLM configured. Se presenta una vulnerabilidad de pérdida de memoria en Cisco IOS versiones anteriores a 15.2(1)T, debido a una pérdida de memoria en el proceso de HTTP PROXY Server (también se conoce como CSCtu52820), cuando se configuró con Cisco ISR Web Security con Cisco ScanSafe y User Authenticaiton NTLM configurado. • https://www.cisco.com/c/en/us/td/docs/ios/15_2m_and_t/release/notes/15_2m_and_t/152-1TCAVS.html • CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.4EPSS: 0%CPEs: 208EXPL: 0CVE-2020-3120 – Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3120
A vulnerability in the Cisco Discovery Protocol implementation for Cisco FXOS Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing check when the affected software processes Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to exhaust system memory, causing the device to reload. Cisco Discovery Protocol is a Layer 2 protocol. • http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-fxnxos-iosxr-cdp-dos • CWE-190: Integer Overflow or Wraparound •
CVSS: 8.8EPSS: 0%CPEs: 53EXPL: 0CVE-2020-3118 – Cisco IOS XR Software Discovery Protocol Format String Vulnerability
https://notcve.org/view.php?id=CVE-2020-3118
A vulnerability in the Cisco Discovery Protocol implementation for Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability is due to improper validation of string input from certain fields in Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device.

CVSS: 7.7EPSS: 0%CPEs: 78EXPL: 0CVE-2019-16027 – Cisco IOS XR Software Intermediate System–to–Intermediate System Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-16027
A vulnerability in the implementation of the Intermediate System–to–Intermediate System (IS–IS) routing protocol functionality in Cisco IOS XR Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition in the IS–IS process. The vulnerability is due to improper handling of a Simple Network Management Protocol (SNMP) request for specific Object Identifiers (OIDs) by the IS–IS process. An attacker could exploit this vulnerability by sending a crafted SNMP request to the affected device. A successful exploit could allow the attacker to cause a DoS condition in the IS–IS process. Una vulnerabilidad en la implementación de la funcionalidad del protocolo de enrutamiento Intermediate System–to–Intermediate System (IS–IS) en Cisco IOS XR Software, podría permitir a un atacante remoto autenticado causar una condición de denegación de servicio (DoS) en el proceso IS–IS. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200122-ios-xr-dos • CWE-20: Improper Input Validation •
