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') •

A vulnerability in Cisco IOS XE Software running on Cisco cBR Series Converged Broadband Routers could allow an unauthenticated, adjacent attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the incorrect handling of certain DHCP packets. An attacker could exploit this vulnerability by sending certain DHCP packets to a specific segment of an affected device. A successful exploit could allow the attacker to increase CPU usage on the affected device and cause a DoS condition.

A vulnerability in the Zone-Based Firewall code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a device to reload. The vulnerability is due to the way fragmented packets are handled in the firewall code. An attacker could exploit this vulnerability by sending fragmented IP Version 4 or IP Version 6 packets through an affected device. An exploit could allow the attacker to cause the device to crash, resulting in a denial of service (DoS) condition. The following releases of Cisco IOS XE Software are vulnerable: Everest-16.4.1, Everest-16.4.2, Everest-16.5.1, Everest-16.5.1b, Everest-16.6.1, Everest-16.6.1a. • http://www.securityfocus.com/bid/103561 http://www.securitytracker.com/id/1040593 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-fwip • CWE-19: Data Processing Errors •

A vulnerability in Cisco IOS XE Software could allow an unauthenticated, remote attacker to log in to a device running an affected release of Cisco IOS XE Software with the default username and password that are used at initial boot, aka a Static Credential Vulnerability. The vulnerability is due to an undocumented user account with privilege level 15 that has a default username and password. An attacker could exploit this vulnerability by using this account to remotely connect to an affected device. A successful exploit could allow the attacker to log in to the device with privilege level 15 access. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software Release 16.x. • http://www.securityfocus.com/bid/103539 http://www.securitytracker.com/id/1040579 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-xesc • CWE-798: Use of Hard-coded Credentials •
