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 •

Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types. La ejecución remota de código es posible con Apache Tomcat en versiones anteriores a 6.0.48, 7.x en versiones anteriores a 7.0.73, 8.x en versiones anteriores a 8.0.39, 8.5.x en versiones anteriores a 8.5.7 y 9.x en versiones anteriores a 9.0.0.M12 si JmxRemoteLifecycleListener es utilizado y un atacante puede llegar a los puertos JMX. El problema existe porque este oyente no se actualizó por coherencia con el parche de Oracle CVE-2016-3427 que afectó a los tipos de credenciales.

CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-6325 – tomcat: tomcat writable config files allow privilege escalation
https://notcve.org/view.php?id=CVE-2016-6325
The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 5 hasta la versión 7, JBoss Web Server 3.0 y JBoss EWS 2 utiliza permisos débiles para (1) /etc/sysconfig/tomcat y (2) /etc/tomcat/tomcat.conf, lo que permite a usuarios locales obtener privilegios aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. • http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93478 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://bugzilla.redhat.com/show_bug.cgi?id=1367447 https://access.redhat.com/security/cve/CVE-2016-6325 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
