CVSS: 9.3EPSS: 0%CPEs: 23EXPL: 0CVE-2021-1433 – Cisco IOS XE SD-WAN Software vDaemon Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2021-1433
A vulnerability in the vDaemon process in Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. This vulnerability is due to insufficient bounds checking when the device processes traffic. An attacker could exploit this vulnerability by sending crafted traffic to the device. The attacker must have a man-in-the-middle position between Cisco vManage and an associated device that is running an affected version of Cisco IOS XE SD-WAN Software. An exploit could allow the attacker to conduct a controllable buffer overflow attack (and possibly execute arbitrary commands as the root user) or cause a device reload, resulting in a denial of service (DoS) condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-buffover-CqdRWLc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.3EPSS: 0%CPEs: 26EXPL: 0CVE-2021-1432 – Cisco IOS XE SD-WAN Software Arbitrary Command Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1432
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as the root user. The attacker must be authenticated on the affected device as a low-privileged user to exploit this vulnerability. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by injecting arbitrary commands to a file as a lower-privileged user. The commands are then executed on the device by the root user. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-sdwarbcmdexec-sspOMUr3 • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

https://notcve.org/view.php?id=CVE-2021-1431
A vulnerability in the vDaemon process of Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a device to reload, resulting a denial of service (DoS) condition. This vulnerability is due to insufficient handling of malformed packets. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

CVSS: 5.3EPSS: 0%CPEs: 23EXPL: 0CVE-2021-1236 – Multiple Cisco Products Snort Application Detection Engine Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1236
Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección de aplicaciones de Snort que podría permitir a un atacante remoto no autenticado omitir las políticas configuradas en un sistema afectado. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-app-bypass-cSBYCATq https://www.debian.org/security/2023/dsa-5354 • CWE-670: Always-Incorrect Control Flow Implementation •
CVSS: 5.8EPSS: 0%CPEs: 48EXPL: 0CVE-2021-1224 – Multiple Cisco Products Snort TCP Fast Open File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1224
Multiple Cisco products are affected by a vulnerability with TCP Fast Open (TFO) when used in conjunction with 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 detection of the HTTP payload if it is contained at least partially within the TFO connection handshake. An attacker could exploit this vulnerability by sending crafted TFO packets with an HTTP payload through an affected device. A successful exploit could allow the attacker to bypass configured file policy for HTTP packets and deliver a malicious payload. Múltiples productos de Cisco están afectados por una vulnerabilidad con TCP Fast Open (TFO) cuando se usan en conjunto con 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-snort-tfo-bypass-MmzZrtes https://www.debian.org/security/2023/dsa-5354 • CWE-693: Protection Mechanism Failure •
