CVSS: 5.3EPSS: 0%CPEs: 64EXPL: 0CVE-2023-45648 – Apache Tomcat: Trailer header parsing too lenient
https://notcve.org/view.php?id=CVE-2023-45648
Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue. Vulnerabilidad de validación de entrada incorrecta en Apache Tomcat.Tomcat desde 11.0.0-M1 hasta 11.0.0-M11, desde 10.1.0-M1 hasta 10.1.13, desde 9.0.0-M1 hasta 9.0.81 y desde 8.5.0 hasta 8.5 .93 no analizaron correctamente los encabezados de las colas HTTP. Un encabezado de avance no válido y especialmente manipulado podría hacer que Tomcat trate una sola solicitud como solicitudes múltiples, lo que genera la posibilidad de contrabando de solicitudes cuando está detrás de un proxy inverso. Se recomienda a los usuarios actualizar a la versión 11.0.0-M12 en adelante, 10.1.14 en adelante, 9.0.81 en adelante o 8.5.94 en adelante, que solucionan el problema. • http://www.openwall.com/lists/oss-security/2023/10/10/10 https://lists.apache.org/thread/2pv8yz1pyp088tsxfb7ogltk9msk0jdp https://lists.debian.org/debian-lts-announce/2023/10/msg00020.html https://security.netapp.com/advisory/ntap-20231103-0007 https://www.debian.org/security/2023/dsa-5521 https://www.debian.org/security/2023/dsa-5522 https://access.redhat.com/security/cve/CVE-2023-45648 https://bugzilla.redhat.com/show_bug.cgi?id=2243749 • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 1%CPEs: 64EXPL: 0CVE-2023-42795 – Apache Tomcat: Failure during request clean-up leads to sensitive data leaking to subsequent requests
https://notcve.org/view.php?id=CVE-2023-42795
Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from 8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. Vulnerabilidad de limpieza incompleta en Apache Tomcat.

Se recomienda a los usuarios actualizar a la versión 11.0.0-M12 en adelante, 10.1.14 en adelante, 9.0.81 en adelante o 8.5.94 en adelante, lo que soluciona el problema.

https://notcve.org/view.php?id=CVE-2023-42794
Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress refactoring that exposed a potential denial of service on Windows if a web application opened a stream for an uploaded file but failed to close the stream. The file would never be deleted from disk creating the possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. Vulnerabilidad de limpieza incompleta en Apache Tomcat. El fork interno de Commons FileUpload empaquetado con Apache Tomcat 9.0.70 a 9.0.80 y 8.5.85 a 8.5.93 incluía una refactorización en curso que expuso una posible denegación de servicio en Windows si una aplicación web abría una secuencia para un archivo cargado pero no lograba cerrar la secuencia. El archivo nunca se eliminaría del disco, creando la posibilidad de una eventual denegación de servicio debido a que el disco esté lleno. • http://www.openwall.com/lists/oss-security/2023/10/10/8 https://lists.apache.org/thread/vvbr2ms7lockj1hlhz5q3wmxb2mwcw82 https://access.redhat.com/security/cve/CVE-2023-42794 https://bugzilla.redhat.com/show_bug.cgi?id=2243751 • CWE-459: Incomplete Cleanup •
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: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-41081 – Apache Tomcat Connectors: Unexpected use of first declared worker in mod_jk for unmapped request
https://notcve.org/view.php?id=CVE-2023-41081
Important: Authentication Bypass CVE-2023-41081 The mod_jk component of Apache Tomcat Connectors in some circumstances, such as when a configuration included "JkOptions +ForwardDirectories" but the configuration did not provide explicit mounts for all possible proxied requests, mod_jk would use an implicit mapping and map the request to the first defined worker. Such an implicit mapping could result in the unintended exposure of the status worker and/or bypass security constraints configured in httpd. As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. Only mod_jk is affected by this issue. The ISAPI redirector is not affected. This issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48. Users are recommended to upgrade to version 1.2.49, which fixes the issue.
