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 •

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. • https://github.com/fullhunt/log4j-scan https://github.com/Puliczek/CVE-2021-44228-PoC-log4j-bypass-words https://github.com/cyberstruggle/L4sh https://github.com/woodpecker-appstore/log4j-payload-generator https://github.com/tangxiaofeng7/apache-log4j-poc https://www.exploit-db.com/exploits/51183 https://www.exploit-db.com/exploits/50592 https://www.exploit-db.com/exploits/50590 https://github.com/logpresso/CVE-2021-44228-Scanner https://github.com/jas502n/Log4j2-CVE-2021-44228 h • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-502: Deserialization of Untrusted Data CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •

A vulnerability in the web-based UI of Cisco Secure Access Control Server could allow an authenticated, remote attacker to gain read access to certain information in an affected system. The vulnerability is due to improper handling of XML External Entities (XXEs) when parsing an XML file. An attacker could exploit this vulnerability by convincing the administrator of an affected system to import a crafted XML file. Una vulnerabilidad en la interfaz web de usuario de Cisco Secure Access Control Server podría permitir que un atacante remoto autenticado obtenga acceso de lectura a determinada información en un sistema afectado. La vulnerabilidad se debe a una gestión incorrecta de XXE (Entidades Externas XML) a la hora de analizar sintácticamente un archivo XML. • http://www.securityfocus.com/bid/105289 http://www.securitytracker.com/id/1041688 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180905-acsxxe • CWE-611: Improper Restriction of XML External Entity Reference •
