CVSS: 7.2EPSS: 0%CPEs: 12EXPL: 0CVE-2019-12709 – Cisco IOS XR Software for Cisco ASR 9000 VMAN CLI Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-12709
A vulnerability in a CLI command related to the virtualization manager (VMAN) in Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with root privileges. The vulnerability is due to insufficient validation of arguments passed to a specific VMAN CLI command on an affected device. An attacker who has valid administrator access to an affected device could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to run arbitrary commands on the underlying operating system with root privileges, which may lead to complete system compromise. Una vulnerabilidad en un comando de la CLI relacionado con el virtualization manager (VMAN) en el Software Cisco IOS XR, para Cisco ASR 9000 Series Aggregation Services Routers, podría permitir a un atacante local autenticado ejecutar comandos arbitrarios en el sistema operativo Linux subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-xr-asr9k-privesc • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
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: 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 •
