CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2019-1710 – Cisco IOS XR 64-Bit Software for Cisco ASR 9000 Series Aggregation Services Routers Network Isolation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1710
A vulnerability in the sysadmin virtual machine (VM) on Cisco ASR 9000 Series Aggregation Services Routers running Cisco IOS XR 64-bit Software could allow an unauthenticated, remote attacker to access internal applications running on the sysadmin VM. The vulnerability is due to incorrect isolation of the secondary management interface from internal sysadmin applications. An attacker could exploit this vulnerability by connecting to one of the listening internal applications. A successful exploit could result in unstable conditions, including both a denial of service and remote unauthenticated access to the device. This vulnerability has been fixed in Cisco IOS XR 64-bit Software Release 6.5.3 and 7.0.1, which will edit the calvados_boostrap.cfg file and reload the device. • http://www.securityfocus.com/bid/108007 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-asr9k-exr • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1681 – Cisco Network Convergence System 1000 Series TFTP Directory Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2019-1681
A vulnerability in the TFTP service of Cisco Network Convergence System 1000 Series software could allow an unauthenticated, remote attacker to retrieve arbitrary files from the targeted device, possibly resulting in information disclosure. The vulnerability is due to improper validation of user-supplied input within TFTP requests processed by the affected software. An attacker could exploit this vulnerability by using directory traversal techniques in malicious requests sent to the TFTP service on a targeted device. An exploit could allow the attacker to retrieve arbitrary files from the targeted device, resulting in the disclosure of sensitive information. This vulnerability affects Cisco IOS XR Software releases prior to Release 6.5.2 for Cisco Network Convergence System 1000 Series devices when the TFTP service is enabled. • http://www.securityfocus.com/bid/107107 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-ncs • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-0418
A vulnerability in the Local Packet Transport Services (LPTS) feature set of Cisco ASR 9000 Series Aggregation Services Router Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of input and validation checking on certain Precision Time Protocol (PTP) ingress traffic to an affected device. An attacker could exploit this vulnerability by injecting malformed traffic into an affected device. A successful exploit could allow the attacker to cause services on the device to become unresponsive, resulting in a DoS condition.

https://notcve.org/view.php?id=CVE-2018-0241
A vulnerability in the UDP broadcast forwarding function of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to improper handling of UDP broadcast packets that are forwarded to an IPv4 helper address. An attacker could exploit this vulnerability by sending multiple UDP broadcast packets to the affected device. An exploit could allow the attacker to cause a buffer leak on the affected device, eventually resulting in a DoS condition requiring manual intervention to recover. This vulnerability affects all Cisco IOS XR platforms running 6.3.1, 6.2.3, or earlier releases of Cisco IOS XR Software when at least one IPv4 helper address is configured on an interface of the device. • http://www.securityfocus.com/bid/103929 http://www.securitytracker.com/id/1040710 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-iosxr • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2018-0136
A vulnerability in the IPv6 subsystem of Cisco IOS XR Software Release 5.3.4 for the Cisco Aggregation Services Router (ASR) 9000 Series could allow an unauthenticated, remote attacker to trigger a reload of one or more Trident-based line cards, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect handling of IPv6 packets with a fragment header extension. An attacker could exploit this vulnerability by sending IPv6 packets designed to trigger the issue either to or through the Trident-based line card. A successful exploit could allow the attacker to trigger a reload of Trident-based line cards, resulting in a DoS during the period of time the line card takes to restart. This vulnerability affects Cisco Aggregation Services Router (ASR) 9000 Series when the following conditions are met: The router is running Cisco IOS XR Software Release 5.3.4, and the router has installed Trident-based line cards that have IPv6 configured. • http://www.securityfocus.com/bid/102905 http://www.securitytracker.com/id/1040315 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180131-ipv6 • CWE-20: Improper Input Validation •
