https://notcve.org/view.php?id=CVE-2018-0472
05 Oct 2018 — 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 all... • http://www.securityfocus.com/bid/105418 • CWE-20: Improper Input Validation •

CVE-2018-0131
https://notcve.org/view.php?id=CVE-2018-0131
14 Aug 2018 — A vulnerability in the implementation of RSA-encrypted nonces in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to obtain the encrypted nonces of an Internet Key Exchange Version 1 (IKEv1) session. The vulnerability exists because the affected software responds incorrectly to decryption failures. An attacker could exploit this vulnerability sending crafted ciphertexts to a device configured with IKEv1 that uses RSA-encrypted nonces. A successful exploit could al... • http://www.securityfocus.com/bid/105074 • CWE-326: Inadequate Encryption Strength •

CVE-2018-0257
https://notcve.org/view.php?id=CVE-2018-0257
19 Apr 2018 — 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... • http://www.securityfocus.com/bid/103948 • CWE-399: Resource Management Errors •

CVE-2018-0194
https://notcve.org/view.php?id=CVE-2018-0194
02 Apr 2018 — Multiple vulnerabilities in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to inject arbitrary commands into the CLI of the affected software, which could allow the attacker to gain access to the underlying Linux shell of an affected device and execute commands with root privileges on the device. The vulnerabilities exist because the affected software does not sufficiently sanitize command arguments before passing commands to the Linux shell for execution. An attacker c... • http://www.securityfocus.com/bid/103547 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

CVE-2018-0188
https://notcve.org/view.php?id=CVE-2018-0188
28 Mar 2018 — Multiple vulnerabilities in the web-based user interface (web UI) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web UI of the affected software. The vulnerabilities are due to insufficient input validation of certain parameters that are passed to the affected software via the web UI. An attacker could exploit these vulnerabilities by persuading a user of the affected UI to access a malicious link or by intercepti... • http://www.securityfocus.com/bid/103551 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2018-0159 – Cisco IOS and XE Software Internet Key Exchange Version 1 Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0159
28 Mar 2018 — A vulnerability in the implementation of Internet Key Exchange Version 1 (IKEv1) functionality in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of specific IKEv1 packets. An attacker could exploit this vulnerability by sending crafted IKEv1 packets to an affected device during an IKE negotiation. A successful exploit could all... • http://www.securityfocus.com/bid/103562 • CWE-20: Improper Input Validation •

CVE-2018-0183
https://notcve.org/view.php?id=CVE-2018-0183
28 Mar 2018 — A vulnerability in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to gain access to the underlying Linux shell of an affected device and execute arbitrary commands with root privileges on the device. The vulnerability is due to the affected software improperly sanitizing command arguments to prevent access to internal data structures on a device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit this vulnerability o... • http://www.securityfocus.com/bid/103555 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •

CVE-2018-0174 – Cisco IOS Software and Cisco IOS XE Software Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2018-0174
28 Mar 2018 — A vulnerability in the DHCP option 82 encapsulation functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software performs incomplete input validation of option 82 information that it receives in DHCP Version 4 (DHCPv4) packets from DHCP relay agents. An attacker could exploit this vulnerability by sending a crafted DH... • http://www.securityfocus.com/bid/103554 • CWE-20: Improper Input Validation •
