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 •
CVSS: 7.8EPSS: 30%CPEs: 114EXPL: 4CVE-2012-1493 – F5 BIG-IP - Authentication Bypass (PoC)
https://notcve.org/view.php?id=CVE-2012-1493
F5 BIG-IP appliances 9.x before 9.4.8-HF5, 10.x before 10.2.4, 11.0.x before 11.0.0-HF2, and 11.1.x before 11.1.0-HF3, and Enterprise Manager before 2.1.0-HF2, 2.2.x before 2.2.0-HF1, and 2.3.x before 2.3.0-HF3, use a single SSH private key across different customers' installations and do not properly restrict access to this key, which makes it easier for remote attackers to perform SSH logins via the PubkeyAuthentication option. El dispositivo F5 BIG-IP v9.x anteriores a v9.4.8-HF5, v10.x anteriores a v10.2.4, v11.0.x anteriores a v11.0.0-HF2, y v11.1.x anteriores a v11.1.0-HF3, y Enterprise Manager anteriores a v2.1.0-HF2, v2.2.x anteriores a v2.2.0-HF1, y v2.3.x anteriores a v2.3.0-HF3, usa una clave privada SSH en distintas instalaciones de clientes, y no restringe el acceso a la mismas de forma adecuada, lo que facilita a atacantes remotos hacer login SSH a través de la opción PubkeyAuthentication. F5 ships a public/private key pair on BIG-IP appliances that allows passwordless authentication to any other BIG-IP box. Since the key is easily retrievable, an attacker can use it to gain unauthorized remote access as root. • https://www.exploit-db.com/exploits/19064 https://www.exploit-db.com/exploits/19091 https://www.exploit-db.com/exploits/19099 http://support.f5.com/kb/en-us/solutions/public/13000/600/sol13600.html http://www.theregister.co.uk/2012/06/13/f5_kit_metasploit_exploit https://github.com/rapid7/metasploit-framework/blob/master/modules/exploits/linux/ssh/f5_bigip_known_privkey.rb https://www.trustmatta.com/advisories/MATTA-2012-002.txt • CWE-255: Credentials Management Errors •
