CVSS: 7.2EPSS: 0%CPEs: 49EXPL: 0CVE-2021-34725 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-34725
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root-level privileges on the underlying operating system. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected 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 execute commands with root-level privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-maapi-privesc-KSUg7QSS • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
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 •

https://notcve.org/view.php?id=CVE-2021-34723
A vulnerability in a specific CLI command that is run on Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the configuration database of an affected device. This vulnerability is due to insufficient validation of specific CLI command parameters. An attacker could exploit this vulnerability by issuing that command with specific parameters. A successful exploit could allow the attacker to overwrite the content of the configuration database and gain root-level access to an affected device. Una vulnerabilidad en un comando CLI específico que se ejecuta en Cisco IOS XE SD-WAN Software podría permitir a un atacante local autenticado sobrescribir archivos arbitrarios en la base de datos de configuración de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxesdwan-arbfileov-MVOF3ZZn • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 6.8EPSS: 0%CPEs: 203EXPL: 0CVE-2021-34703 – Cisco IOS and IOS XE Software Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34703
A vulnerability in the Link Layer Discovery Protocol (LLDP) message parser of Cisco IOS Software and Cisco IOS XE Software could allow an attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to improper initialization of a buffer. An attacker could exploit this vulnerability via any of the following methods: An authenticated, remote attacker could access the LLDP neighbor table via either the CLI or SNMP while the device is in a specific state. An unauthenticated, adjacent attacker could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then waiting for an administrator of the device or a network management system (NMS) managing the device to retrieve the LLDP neighbor table of the device via either the CLI or SNMP. An authenticated, adjacent attacker with SNMP read-only credentials or low privileges on the device CLI could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then accessing the LLDP neighbor table via either the CLI or SNMP. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-lldp-dos-sBnuHSjT • CWE-456: Missing Initialization of a Variable CWE-665: Improper Initialization •
CVSS: 5.8EPSS: 0%CPEs: 26EXPL: 0CVE-2021-1495 – Multiple Cisco Products Snort HTTP Detection Engine File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1495
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured file policy for HTTP. The vulnerability is due to incorrect handling of specific HTTP header parameters. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured file policy for HTTP packets and deliver a malicious payload. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección Snort que podría permitir a un atacante remoto no autenticado omitir una política de archivos configurada para HTTP. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-http-fp-bp-KfDdcQhc https://www.debian.org/security/2023/dsa-5354 • CWE-755: Improper Handling of Exceptional Conditions •
