CVSS: 7.1EPSS: 0%CPEs: 149EXPL: 0CVE-2018-0282 – Cisco IOS and IOS XE Software TCP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0282
A vulnerability in the TCP socket code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a state condition between the socket state and the transmission control block (TCB) state. While this vulnerability potentially affects all TCP applications, the only affected application observed so far is the HTTP server. An attacker could exploit this vulnerability by sending specific HTTP requests at a sustained rate to a reachable IP address of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition on an affected device. • http://www.securityfocus.com/bid/106510 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190109-tcp • CWE-371: State Issues •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0475 – Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0475
A vulnerability in the implementation of the cluster feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation when handling Cluster Management Protocol (CMP) messages. An attacker could exploit this vulnerability by sending a malicious CMP message to an affected device. A successful exploit could allow the attacker to cause the switch to crash and reload or to hang, resulting in a DoS condition. If the switch hangs it will not reboot automatically, and it will need to be power cycled manually to recover. • http://www.securityfocus.com/bid/105404 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cmp • CWE-20: Improper Input Validation •
CVSS: 6.5EPSS: 0%CPEs: 1195EXPL: 0CVE-2018-0197 – Cisco IOS and IOS XE Software VLAN Trunking Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0197
A vulnerability in the VLAN Trunking Protocol (VTP) subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to corrupt the internal VTP database on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to a logic error in how the affected software handles a subset of VTP packets. An attacker could exploit this vulnerability by sending VTP packets in a sequence that triggers a timeout in the VTP message processing code of the affected software. A successful exploit could allow the attacker to impact the ability to create, modify, or delete VLANs and cause a DoS condition. There are workarounds that address this vulnerability. • http://www.securityfocus.com/bid/105424 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-vtp • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0473 – Cisco IOS Software Precision Time Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0473
A vulnerability in the Precision Time Protocol (PTP) subsystem of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of the Precision Time Protocol. The vulnerability is due to insufficient processing of PTP packets. An attacker could exploit this vulnerability by sending a custom PTP packet to, or through, an affected device. A successful exploit could allow the attacker to cause a DoS condition for the PTP subsystem, resulting in time synchronization issues across the network. Una vulnerabilidad en el subsistema Precision Time Protocol (PTP) de Cisco NX-OS Software podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en el protocolo PTP. • http://www.securityfocus.com/bid/105427 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-ptp • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2018-0255
A vulnerability in the device manager web interface of Cisco Industrial Ethernet Switches could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack against a user of an affected system. The vulnerability is due to insufficient CSRF protection by the device manager web interface. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link or visit an attacker-controlled website. A successful exploit could allow the attacker to submit arbitrary requests to an affected device via the device manager web interface with the privileges of the user. This vulnerability affects the following Cisco Industrial Ethernet (IE) Switches if they are running a vulnerable release of Cisco IOS Software: IE 2000 Series, IE 2000U Series, IE 3000 Series, IE 3010 Series, IE 4000 Series, IE 4010 Series, IE 5000 Series. • http://www.securitytracker.com/id/1040715 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-iess • CWE-352: Cross-Site Request Forgery (CSRF) •
