CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0485 – Cisco IOS and IOS XE Software SM-1T3/E3 Service Module Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0485
A vulnerability in the SM-1T3/E3 firmware on Cisco Second Generation Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated Services Router (ISR4451-X) could allow an unauthenticated, remote attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of user input. An attacker could exploit this vulnerability by first connecting to the SM-1T3/E3 module console and entering a string sequence. A successful exploit could allow the attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a DoS condition on an affected device. Una vulnerabilidad en el firmware SM-1T3/E3 en Cisco Second Generation Integrated Services Routers (ISR G2) y Cisco 4451-X Integrated Services Router (ISR4451-X) podría permitir que un atacante remoto no autenticado provoque que el router ISR G2 o el módulo SM-1T3/E3 en ISR4451-X se recargue, resultando en una denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/105433 http://www.securitytracker.com/id/1041736 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-sm1t3e3 • CWE-19: Data Processing Errors CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0472 – Cisco IOS XE Software and Cisco ASA 5500-X Series Adaptive Security Appliance IPsec Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0472
A vulnerability in the IPsec driver code of multiple Cisco IOS XE Software platforms and the Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to improper processing of malformed IPsec Authentication Header (AH) or Encapsulating Security Payload (ESP) packets. An attacker could exploit this vulnerability by sending malformed IPsec packets to be processed by an affected device. An exploit could allow the attacker to cause a reload of the affected device. Una vulnerabilidad en el código del controlador IPsec de múltiples plataformas Cisco IOS XE Software y Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) podría permitir que un atacante remoto no autenticado provoque la recarga del dispositivo. • http://www.securityfocus.com/bid/105418 http://www.securitytracker.com/id/1041735 http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-04 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ipsec • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0470 – Cisco IOS XE Software HTTP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0470
A vulnerability in the web framework of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a buffer overflow condition on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the affected software improperly parsing malformed HTTP packets that are destined to a device. An attacker could exploit this vulnerability by sending a malformed HTTP packet to an affected device for processing. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, resulting in a DoS condition. Una vulnerabilidad en el framework web de Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar provoque un desbordamiento de búfer en un dispositivo afectado, lo que resulta en una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105397 http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-webdos • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •
CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0481 – Cisco IOS XE Software Command Injection Vulnerabilities
https://notcve.org/view.php?id=CVE-2018-0481
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: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-2018-15374 – Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2018-15374
A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install a malicious software image or file on an affected device. The vulnerability is due to the affected software improperly verifying digital signatures for software images and files that are uploaded to a device. An attacker could exploit this vulnerability by uploading a malicious software image or file to an affected device. A successful exploit could allow the attacker to bypass digital signature verification checks for software images and files and install a malicious software image or file on the affected device. Una vulnerabilidad en la funcionalidad de verificación de imágenes de Cisco IOS XE Software podría permitir que un atacante local autenticado instale una imagen o archivo de software malicioso en un dispositivo afectado. • http://www.securityfocus.com/bid/105415 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-digsig • CWE-347: Improper Verification of Cryptographic Signature •
