CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 1CVE-2023-36478 – HTTP/2 HPACK integer overflow and buffer allocation
https://notcve.org/view.php?id=CVE-2023-36478
Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. • http://www.openwall.com/lists/oss-security/2023/10/18/4 https://github.com/eclipse/jetty.project/pull/9634 https://github.com/eclipse/jetty.project/releases/tag/jetty-10.0.16 https://github.com/eclipse/jetty.project/releases/tag/jetty-11.0.16 https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.53.v20231009 https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgh7-54f2-x98r https://lists.debian.org/debian-lts-announce/2023/10/msg00045.html https:&# • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
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 •

In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using MultipartFormDataParser creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used. En Jenkins versión 2.423 y anteriores, LTS versión 2.414.1 y anteriores, el procesamiento de cargas de archivos utilizando MultipartFormDataParser crea archivos temporales en el directorio temporal predeterminado del sistema con los permisos predeterminados para archivos recién creados, lo que potencialmente permite a los atacantes con acceso al sistema de archivos del controlador Jenkins leer y escriba los archivos antes de usarlos. • http://www.openwall.com/lists/oss-security/2023/09/20/5 https://www.jenkins.io/security/advisory/2023-09-20/#SECURITY-3073 • CWE-377: Insecure Temporary File •
