CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1910 – Cisco IOS XR Software Intermediate System to Intermediate System Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1910
A vulnerability in the implementation of the Intermediate System–to–Intermediate System (IS–IS) routing protocol functionality in Cisco IOS XR Software could allow an unauthenticated attacker who is in the same IS–IS area to cause a denial of service (DoS) condition. The vulnerability is due to incorrect processing of crafted IS–IS link-state protocol data units (PDUs). An attacker could exploit this vulnerability by sending a crafted link-state PDU to an affected system to be processed. A successful exploit could allow the attacker to cause all routers within the IS–IS area to unexpectedly restart the IS–IS process, resulting in a DoS condition. This vulnerability affects Cisco devices if they are running a vulnerable release of Cisco IOS XR Software earlier than Release 6.6.3 and are configured with the IS–IS routing protocol. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190807-iosxr-isis-dos-1910 • CWE-20: Improper Input Validation •
CVSS: 6.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-1909 – Cisco IOS XR Software Border Gateway Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1909
A vulnerability in the implementation of Border Gateway Protocol (BGP) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to incorrect processing of certain BGP update messages. An attacker could exploit this vulnerability by sending BGP update messages that include a specific set of attributes to be processed by an affected system. A successful exploit could allow the attacker to cause the BGP process to restart unexpectedly, resulting in a DoS condition. The Cisco implementation of BGP accepts incoming BGP traffic from explicitly defined peers only. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-iosxr-bgp-dos • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2019-1712 – Cisco IOS XR Software Protocol Independent Multicast Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1712
A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the PIM process to restart, resulting in a denial of service condition on an affected device. The vulnerability is due to the incorrect processing of crafted AutoRP packets. An attacker could exploit this vulnerability by sending crafted packets to port UDP 496 on a reachable IP address on the device. A successful exploit could allow the attacker to cause the PIM process to restart. Software versions prior to 6.2.3, 6.3.2, 6.4.0, and 6.5.1 are affected. • http://www.securityfocus.com/bid/108025 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-iosxr-pim-dos • CWE-20: Improper Input Validation •
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 •
