CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1711 – Cisco IOS XR gRPC Software Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1711
A vulnerability in the Event Management Service daemon (emsd) of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of gRPC requests. An attacker could exploit this vulnerability by repeatedly sending unauthenticated gRPC requests to the affected device. A successful exploit could cause the emsd process to crash, resulting in a DoS condition. Resolved in Cisco IOS XR 6.5.1 and later. • http://www.securityfocus.com/bid/108017 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-ios-xr-dos • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 12EXPL: 0CVE-2019-1686 – Cisco ASR 9000 Series Aggregation Services Routers ACL Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1686
A vulnerability in the TCP flags inspection feature for access control lists (ACLs) on Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to bypass protection offered by a configured ACL on an affected device. The vulnerability is due to incorrect processing of the ACL applied to an interface of an affected device when Cisco Express Forwarding load balancing using the 3-tuple hash algorithm is enabled. An attacker could exploit this vulnerability by sending traffic through an affected device that should otherwise be denied by the configured ACL. An exploit could allow the attacker to bypass protection offered by a configured ACL on the affected device. There are workarounds that address this vulnerability. • http://www.securityfocus.com/bid/108026 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-iosxracl • CWE-284: Improper Access Control •
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 •
CVSS: 6.8EPSS: 0%CPEs: 19EXPL: 0CVE-2018-15428 – Cisco IOS XR Software Border Gateway Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15428
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. 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, malformed attribute 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 only from explicitly defined peers. • http://www.securitytracker.com/id/1041790 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-iosxr-dos • CWE-20: Improper Input Validation •
