CVSS: 10.0EPSS: 3%CPEs: 2EXPL: 0CVE-2018-0151 – Cisco IOS Software and Cisco IOS XE Software Quality of Service Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2018-0151
A vulnerability in the quality of service (QoS) subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges. The vulnerability is due to incorrect bounds checking of certain values in packets that are destined for UDP port 18999 of an affected device. An attacker could exploit this vulnerability by sending malicious packets to an affected device. When the packets are processed, an exploitable buffer overflow condition may occur. A successful exploit could allow the attacker to execute arbitrary code on the affected device with elevated privileges. • http://www.securityfocus.com/bid/103540 http://www.securitytracker.com/id/1040582 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-qos • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.6EPSS: 0%CPEs: 15EXPL: 0CVE-2018-0155 – Cisco Catalyst Bidirectional Forwarding Detection Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0155
A vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to cause a crash of the iosd process, causing a denial of service (DoS) condition. The vulnerability is due to insufficient error handling when the BFD header in a BFD packet is incomplete. An attacker could exploit this vulnerability by sending a crafted BFD message to or across an affected switch. A successful exploit could allow the attacker to trigger a reload of the system. This vulnerability affects Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5), Catalyst 4948E Ethernet Switch (K5). • http://www.securityfocus.com/bid/103565 http://www.securitytracker.com/id/1040587 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-05 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-bfd • CWE-388: 7PK - Errors CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.8EPSS: 0%CPEs: 298EXPL: 0CVE-2018-0156 – Cisco IOS Software and Cisco IOS XE Software Smart Install Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0156
A vulnerability in the Smart Install feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of packet data. An attacker could exploit this vulnerability by sending a crafted packet to an affected device on TCP port 4786. Only Smart Install client switches are affected. Cisco devices that are configured as a Smart Install director are not affected by this vulnerability. • http://www.securityfocus.com/bid/103569 http://www.securitytracker.com/id/1040596 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-04 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-05 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-smi • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •
CVSS: 8.6EPSS: 2%CPEs: 59EXPL: 0CVE-2018-0158 – Cisco IOS and XE Software Internet Key Exchange Memory Leak Vulnerability
https://notcve.org/view.php?id=CVE-2018-0158
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition.

CVSS: 7.8EPSS: 0%CPEs: 26EXPL: 0CVE-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
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 allow the attacker to cause an affected device to reload, resulting in a DoS condition.
