CVSS: 7.5EPSS: 83%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 •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2022-20762 – Cisco Ultra Cloud Core - Subscriber Microservices Infrastructure Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-20762
A vulnerability in the Common Execution Environment (CEE) ConfD CLI of Cisco Ultra Cloud Core - Subscriber Microservices Infrastructure (SMI) software could allow an authenticated, local attacker to escalate privileges on an affected device. This vulnerability is due to insufficient access control in the affected CLI. An attacker could exploit this vulnerability by authenticating as a CEE ConfD CLI user and executing a specific CLI command. A successful exploit could allow an attacker to access privileged containers with root privileges.

CVSS: 7.2EPSS: 0%CPEs: 5EXPL: 0CVE-2022-20665 – Cisco StarOS Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2022-20665
A vulnerability in the CLI of Cisco StarOS could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient input validation of CLI commands. An attacker could exploit this vulnerability by sending crafted commands to the CLI. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the root user. To exploit this vulnerability, an attacker would need to have valid administrative credentials on an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-staros-cmdinj-759mNT4n • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
