CVSS: 6.6EPSS: 0%CPEs: 49EXPL: 0CVE-2021-34724 – Cisco IOS XE SD-WAN Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34724
A vulnerability in the Cisco IOS XE SD-WAN Software CLI could allow an authenticated, local attacker to elevate privileges and execute arbitrary code on the underlying operating system as the root user. An attacker must be authenticated on an affected device as a PRIV15 user. This vulnerability is due to insufficient file system protection and the presence of a sensitive file in the bootflash directory on an affected device. An attacker could exploit this vulnerability by overwriting an installer file stored in the bootflash directory with arbitrary commands that can be executed with root-level privileges. A successful exploit could allow the attacker to read and write changes to the configuration database on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxesdwan-privesc-VP4FG3jD • CWE-284: Improper Access Control •
CVSS: 7.2EPSS: 0%CPEs: 63EXPL: 1CVE-2021-1383 – Cisco IOS XE SD-WAN Software Parameter Injection Vulnerabilities
https://notcve.org/view.php?id=CVE-2021-1383
Multiple vulnerabilities in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to access the underlying operating system with root privileges. These vulnerabilities are due to insufficient input validation of certain CLI commands. An attacker could exploit these vulnerabilities by authenticating to the device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to access the underlying operating system with root privileges. • https://github.com/orangecertcc/security-research/security/advisories/GHSA-vw54-f9mw-g46r https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xesdwpinj-V4weeqzU • CWE-20: Improper Input Validation CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
CVSS: 10.0EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3375 – Cisco SD-WAN Solution Software Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2020-3375
A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to information that they are not authorized to access, make changes to the system that they are not authorized to make, and execute commands on an affected system with privileges of the root user. Una vulnerabilidad en Cisco SD-WAN Solution Software podría permitir a un atacante remoto no autenticado causar un desbordamiento del búfer sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdbufof-h5f5VSeL • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3216 – Cisco IOS XE SD-WAN Software Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3216
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, physical attacker to bypass authentication and gain unrestricted access to the root shell of an affected device. The vulnerability exists because the affected software has insufficient authentication mechanisms for certain commands. An attacker could exploit this vulnerability by stopping the boot initialization of an affected device. A successful exploit could allow the attacker to bypass authentication and gain unrestricted access to the root shell of the affected device. Una vulnerabilidad en Cisco IOS XE SD-WAN Software, podría permitir a un atacante físico no autenticado omitir la autenticación y conseguir acceso sin restricciones al shell root de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-auth-b-NzwhJHH7 • CWE-287: Improper Authentication •
