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: 3EXPL: 0CVE-2020-3272 – Cisco Prime Network Registrar DHCP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3272
A vulnerability in the DHCP server of Cisco Prime Network Registrar could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation of incoming DHCP traffic. An attacker could exploit this vulnerability by sending a crafted DHCP request to an affected device. A successful exploit could allow the attacker to cause a restart of the DHCP server process, causing a DoS condition. Una vulnerabilidad en el servidor DHCP de Cisco Prime Network Registrar, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cpnr-dhcp-dos-BkEZfhLP • CWE-20: Improper Input Validation •
CVSS: 7.1EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3148 – Cisco Prime Network Registrar Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2020-3148
A vulnerability in the web-based interface of Cisco Prime Network Registrar (CPNR) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections in the web-based interface. An attacker could exploit this vulnerability by persuading a targeted user, with an active administrative session on the affected device, to click a malicious link. A successful exploit could allow an attacker to change the device's configuration, which could include the ability to edit or create user accounts of any privilege level. Some changes to the device's configuration could negatively impact the availability of networking services for other devices on networks managed by CPNR. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cpnr-csrf-WWTrDkyL • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1840 – Cisco Prime Network Registrar Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1840
A vulnerability in the DHCPv6 input packet processor of Cisco Prime Network Registrar could allow an unauthenticated, remote attacker to restart the server and cause a denial of service (DoS) condition on the affected system. The vulnerability is due to incomplete user-supplied input validation when a custom extension attempts to change a DHCPv6 packet received by the application. An attacker could exploit this vulnerability by sending malformed DHCPv6 packets to the application. An exploit could allow the attacker to trigger a restart of the service which, if exploited repeatedly, might lead to a DoS condition. This vulnerability can only be exploited if the administrator of the server has previously installed custom extensions that attempt to modify the packet details before the packet has been processed. • http://www.securityfocus.com/bid/108033 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-pnr-dos • CWE-665: Improper Initialization •
