CVSS: 7.5EPSS: 81%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2023-20235
A vulnerability in the on-device application development workflow feature for the Cisco IOx application hosting infrastructure in Cisco IOS XE Software could allow an authenticated, remote attacker to access the underlying operating system as the root user. This vulnerability exists because Docker containers with the privileged runtime option are not blocked when they are in application development mode. An attacker could exploit this vulnerability by using the Docker CLI to access an affected device. The application development workflow is meant to be used only on development systems and not in production systems. Una vulnerabilidad en la función de flujo de trabajo de desarrollo de aplicaciones en el dispositivo para la infraestructura de alojamiento de aplicaciones Cisco IOx en el software Cisco IOS XE podría permitir que un atacante remoto autenticado acceda al sistema operativo subyacente como usuario root. Esta vulnerabilidad existe porque los contenedores Docker con la opción de tiempo de ejecución privilegiado no se bloquean cuando están en modo de desarrollo de aplicaciones. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rdocker-uATbukKn • CWE-269: Improper Privilege Management CWE-552: Files or Directories Accessible to External Parties •
CVSS: 6.5EPSS: 0%CPEs: 64EXPL: 0CVE-2023-20056 – Cisco Access Point Software Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-20056
A vulnerability in the management CLI of Cisco access point (AP) software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to cause an affected device to reload spontaneously, resulting in a DoS condition. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-cli-dos-tc2EKEpu • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2023-20097
A vulnerability in Cisco access points (AP) software could allow an authenticated, local attacker to inject arbitrary commands and execute them with root privileges. This vulnerability is due to improper input validation of commands that are issued from a wireless controller to an AP. An attacker with Administrator access to the CLI of the controller could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to gain full root access on the AP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironetap-cmdinj-6bjT4FL8 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 6.8EPSS: 0%CPEs: 46EXPL: 0CVE-2023-20082 – Cisco IOS XE Software for Cisco Catalyst 9300 Series Switches Secure Boot Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2023-20082
A vulnerability in Cisco IOS XE Software for Cisco Catalyst 9300 Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust. This vulnerability is due to errors that occur when retrieving the public release key that is used for image signature verification. An attacker could exploit this vulnerability by modifying specific variables in the Serial Peripheral Interface (SPI) flash memory of an affected device. A successful exploit could allow the attacker to execute persistent code on the underlying operating system. Note: In Cisco IOS XE Software releases 16.11.1 and later, the complexity of an attack using this vulnerability is high. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-c9300-spi-ace-yejYgnNQ • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
