CVE-2020-3545 – Cisco FXOS Software Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2020-3545
A vulnerability in Cisco FXOS Software could allow an authenticated, local attacker with administrative credentials to cause a buffer overflow condition. The vulnerability is due to incorrect bounds checking of values that are parsed from a specific file. An attacker could exploit this vulnerability by supplying a crafted file that, when it is processed, may cause a stack-based buffer overflow. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system with root privileges. An attacker would need to have valid administrative credentials to exploit this vulnerability. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fxos-buffer-cSdmfWUt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2020-3166 – Cisco FXOS Software CLI Arbitrary File Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2020-3166
A vulnerability in the CLI of Cisco FXOS Software could allow an authenticated, local attacker to read or write arbitrary files on the underlying operating system (OS). The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by including crafted arguments to a specific CLI command. A successful exploit could allow the attacker to read or write to arbitrary files on the underlying OS. Una vulnerabilidad en la CLI de Cisco FXOS Software, podría permitir a un atacante local autenticado leer o escribir archivos arbitrarios en el sistema operativo (SO) subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fxos-cli-file • CWE-20: Improper Input Validation •
CVE-2020-3167 – Cisco FXOS and UCS Manager Software CLI Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3167
A vulnerability in the CLI of Cisco FXOS Software and Cisco UCS Manager Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS). The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by including crafted arguments to specific commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS with the privileges of the currently logged-in user for all affected platforms excluding Cisco UCS 6400 Series Fabric Interconnects. On Cisco UCS 6400 Series Fabric Interconnects, the injected commands are executed with root privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fxos-ucs-cmdinj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2020-3169 – Cisco FXOS Software CLI Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3169
A vulnerability in the CLI of Cisco FXOS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with a privilege level of root on an affected device. The vulnerability is due to insufficient validation of arguments passed to a specific CLI command on the affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with root privileges. An attacker would need valid administrator credentials to exploit this vulnerability. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fpwr-cmdinj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2020-3172 – Cisco FXOS and NX-OS Software Cisco Discovery Protocol Arbitrary Code Execution and Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3172
A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code as root or cause a DoS condition on the affected device. Note: Cisco Discovery Protocol is a Layer 2 protocol. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fxos-nxos-cdp • CWE-20: Improper Input Validation •
