CVSS: 8.8EPSS: 0%CPEs: 47EXPL: 0CVE-2023-20076 – Cisco IOx Application Hosting Environment Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2023-20076
A vulnerability in the Cisco IOx application hosting environment could allow an authenticated, remote attacker to execute arbitrary commands as root on the underlying host operating system. This vulnerability is due to incomplete sanitization of parameters that are passed in for activation of an application. An attacker could exploit this vulnerability by deploying and activating an application in the Cisco IOx application hosting environment with a crafted activation payload file. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying host operating system. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-8whGn5dL • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-233: Improper Handling of Parameters •
CVSS: 7.7EPSS: 0%CPEs: 1446EXPL: 0CVE-2022-20920 – Cisco IOS and IOS XE Software SSH Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20920
A vulnerability in the SSH implementation of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. This vulnerability is due to improper handling of resources during an exceptional situation. An attacker could exploit this vulnerability by continuously connecting to an affected device and sending specific SSH requests. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en la implementación de SSH del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto autenticado causara la recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssh-excpt-dos-FzOBQTnk • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.7EPSS: 0%CPEs: 109EXPL: 0CVE-2022-20679 – Cisco IOS XE Software IPSec Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20679
A vulnerability in the IPSec decryption routine of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to buffer exhaustion that occurs while traffic on a configured IPsec tunnel is being processed. An attacker could exploit this vulnerability by sending traffic to an affected device that has a maximum transmission unit (MTU) of 1800 bytes or greater. A successful exploit could allow the attacker to cause the device to reload. To exploit this vulnerability, the attacker may need access to the trusted network where the affected device is in order to send specific packets to be processed by the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-qfp-ipsec-GQmqvtqV • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 62EXPL: 0CVE-2022-20682 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20682
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to inadequate input validation of incoming CAPWAP packets encapsulating multicast DNS (mDNS) queries. An attacker could exploit this vulnerability by connecting to a wireless network and sending a crafted mDNS query, which would flow through and be processed by the wireless controller. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento del protocolo de control y aprovisionamiento de puntos de acceso inalámbricos (CAPWAP) de Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-c9800-capwap-mdns-6PSn7gKU • CWE-476: NULL Pointer Dereference CWE-690: Unchecked Return Value to NULL Pointer Dereference •
CVSS: 8.6EPSS: 0%CPEs: 101EXPL: 0CVE-2022-20683 – Cisco IOS XE Software for Catalyst 9800 Series Wireless Controllers Application Visibility and Control Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20683
A vulnerability in the Application Visibility and Control (AVC-FNF) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient packet verification for traffic inspected by the AVC feature. An attacker could exploit this vulnerability by sending crafted packets from the wired network to a wireless client, resulting in the crafted packets being processed by the wireless controller. A successful exploit could allow the attacker to cause a crash and reload of the affected device, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad de visibilidad y control de aplicaciones (AVC-FNF) de Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-c9800-fnf-dos-bOL5vLge • CWE-124: Buffer Underwrite ('Buffer Underflow') CWE-787: Out-of-bounds Write •
