CVSS: 8.1EPSS: 0%CPEs: 50EXPL: 0CVE-2021-1227 – Cisco NX-OS Software NX-API Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2021-1227
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. This vulnerability is due to insufficient CSRF protections for the NX-API on an affected device. An attacker could exploit this vulnerability by persuading a user of the NX-API to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user. The attacker could view and modify the device configuration. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-nxapi-csrf-wRMzWL9z • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 8.6EPSS: 0%CPEs: 386EXPL: 0CVE-2020-3517 – Cisco FXOS and NX-OS Software Cisco Fabric Services Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3517
A vulnerability in the Cisco Fabric Services component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated attacker to cause process crashes, which could result in a denial of service (DoS) condition on an affected device. The attack vector is configuration dependent and could be remote or adjacent. For more information about the attack vector, see the Details section of this advisory. The vulnerability is due to insufficient error handling when the affected software parses Cisco Fabric Services messages. An attacker could exploit this vulnerability by sending malicious Cisco Fabric Services messages to an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fxos-nxos-cfs-dos-dAmnymbd • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 0CVE-2020-3338 – Cisco NX-OS Software IPv6 Protocol Independent Multicast Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3338
A vulnerability in the Protocol Independent Multicast (PIM) feature for IPv6 networks (PIM6) of Cisco NX-OS 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 error handling when processing inbound PIM6 packets. An attacker could exploit this vulnerability by sending multiple crafted PIM6 packets to an affected device. A successful exploit could allow the attacker to cause the PIM6 application to leak system memory. Over time, this memory leak could cause the PIM6 application to stop processing legitimate PIM6 traffic, leading to a DoS condition on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-pim-memleak-dos-tC8eP7uw • CWE-404: Improper Resource Shutdown or Release CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.6EPSS: 0%CPEs: 67EXPL: 0CVE-2020-3398 – Cisco NX-OS Software Border Gateway Protocol Multicast VPN Session Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3398
A vulnerability in the Border Gateway Protocol (BGP) Multicast VPN (MVPN) implementation of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a BGP session to repeatedly reset, causing a partial denial of service (DoS) condition due to the BGP session being down. The vulnerability is due to incorrect parsing of a specific type of BGP MVPN update message. An attacker could exploit this vulnerability by sending this BGP MVPN update message to a targeted device. A successful exploit could allow the attacker to cause the BGP peer connections to reset, which could lead to BGP route instability and impact traffic. The incoming BGP MVPN update message is valid but is parsed incorrectly by the NX-OS device, which could send a corrupted BGP update to the configured BGP peer. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxosbgp-mvpn-dos-K8kbCrJp • CWE-20: Improper Input Validation •
CVSS: 9.0EPSS: 0%CPEs: 83EXPL: 0CVE-2020-3454 – Cisco NX-OS Software Call Home Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3454
A vulnerability in the Call Home feature of Cisco NX-OS Software could allow an authenticated, remote attacker to inject arbitrary commands that could be executed with root privileges on the underlying operating system (OS). The vulnerability is due to insufficient input validation of specific Call Home configuration parameters when the software is configured for transport method HTTP. An attacker could exploit this vulnerability by modifying parameters within the Call Home configuration on an affected device. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying OS. Una vulnerabilidad en la funcionalidad Call Home de Cisco NX-OS Software, podría permitir a un atacante remoto autenticado inyectar comandos arbitrarios que podrían ser ejecutados con privilegios root en el sistema operativo (SO) subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-callhome-cmdinj-zkxzSCY • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
