CVSS: 10.0EPSS: 85%CPEs: 1EXPL: 1CVE-2018-0171 – Cisco IOS and IOS XE Software Smart Install Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2018-0171
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, or to execute arbitrary code on an affected device. The vulnerability is due to improper validation of packet data. An attacker could exploit this vulnerability by sending a crafted Smart Install message to an affected device on TCP port 4786. A successful exploit could allow the attacker to cause a buffer overflow on the affected device, which could have the following impacts: Triggering a reload of the device, Allowing the attacker to execute arbitrary code on the device, Causing an indefinite loop on the affected device that triggers a watchdog crash.

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: 8.6EPSS: 1%CPEs: 24EXPL: 0CVE-2018-0173 – Cisco IOS and IOS XE Software Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2018-0173
A vulnerability in the Cisco IOS Software and Cisco IOS XE Software function that restores encapsulated option 82 information in DHCP Version 4 (DHCPv4) packets could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a Relay Reply denial of service (DoS) condition. The vulnerability exists because the affected software performs incomplete input validation of encapsulated option 82 information that it receives in DHCPOFFER messages from DHCPv4 servers. An attacker could exploit this vulnerability by sending a crafted DHCPv4 packet to an affected device, which the device would then forward to a DHCPv4 server. When the affected software processes the option 82 information that is encapsulated in the response from the server, an error could occur. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. • http://www.securityfocus.com/bid/103545 http://www.securitytracker.com/id/1040591 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-dhcpr2 https://www.tenable.com/security/research/tra-2018-06 • CWE-20: Improper Input Validation •
CVSS: 6.3EPSS: 0%CPEs: 15EXPL: 0CVE-2018-0161 – Cisco IOS Software Resource Management Errors Vulnerability
https://notcve.org/view.php?id=CVE-2018-0161
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS Software running on certain models of Cisco Catalyst Switches could allow an authenticated, remote attacker to cause a denial of service (DoS) condition, aka a GET MIB Object ID Denial of Service Vulnerability. The vulnerability is due to a condition that could occur when the affected software processes an SNMP read request that contains a request for the ciscoFlashMIB object ID (OID). An attacker could trigger this vulnerability by issuing an SNMP GET request for the ciscoFlashMIB OID on an affected device. A successful exploit could cause the affected device to restart due to a SYS-3-CPUHOG. This vulnerability affects the following Cisco devices if they are running a vulnerable release of Cisco IOS Software and are configured to use SNMP Version 2 (SNMPv2) or SNMP Version 3 (SNMPv3): Cisco Catalyst 2960-L Series Switches, Cisco Catalyst Digital Building Series Switches 8P, Cisco Catalyst Digital Building Series Switches 8U. • http://www.securityfocus.com/bid/103573 http://www.securitytracker.com/id/1040589 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-snmp • CWE-399: Resource Management Errors •
