2021-12-20 CVE-2021-44790 A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. Http_server, Mac_os_x, Macos, Debian_linux, Fedora, Cloud_backup, Communications_element_manager, Communications_operations_monitor, Communications_session_report_manager, Communications_session_route_manager, Http_server, Instantis_enterprisetrack, Zfs_storage_appliance_kit, Tenable\.sc 9.8
2020-10-12 CVE-2020-13943 If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources. Tomcat, Debian_linux, Instantis_enterprisetrack, Sd\-Wan_edge 4.3
2021-06-29 CVE-2021-33503 An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in the authority component, the authority regular expression exhibits catastrophic backtracking, causing a denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect. Fedora, Enterprise_manager_ops_center, Instantis_enterprisetrack, Zfs_storage_appliance_kit, Urllib3 7.5
2019-08-13 CVE-2019-9517 Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. Http_server, Traffic_server, Swiftnio, Ubuntu_linux, Debian_linux, Fedora, Web_gateway, Clustered_data_ontap, Node\.js, Leap, Communications_element_manager, Graalvm, Instantis_enterprisetrack, Retail_xstore_point_of_service, Enterprise_linux, Jboss_core_services, Jboss_enterprise_application_platform, Openshift_service_mesh, Quay, Software_collections, Diskstation_manager, Skynas, Vs960hd_firmware 7.5
2020-11-12 CVE-2019-17566 Apache Batik is vulnerable to server-side request forgery, caused by improper input validation by the "xlink:href" attributes. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests. Batik, Api_gateway, Business_intelligence, Communications_application_session_controller, Communications_metasolv_solution, Communications_offline_mediation_controller, Enterprise_repository, Financial_services_analytical_applications_infrastructure, Fusion_middleware_mapviewer, Hospitality_opera_5, Hyperion_financial_reporting, Instantis_enterprisetrack, Jd_edwards_enterpriseone_tools, Retail_integration_bus, Retail_order_broker, Retail_order_management_system_cloud_service, Retail_point\-Of\-Service, Retail_returns_management 7.5
2021-12-20 CVE-2021-44224 A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). Http_server, Mac_os_x, Macos, Debian_linux, Fedora, Communications_element_manager, Communications_operations_monitor, Communications_session_report_manager, Communications_session_route_manager, Http_server, Instantis_enterprisetrack, Tenable\.sc 8.2
2021-09-16 CVE-2021-34798 Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. Http_server, Brocade_fabric_operating_system_firmware, Debian_linux, Fedora, Cloud_backup, Clustered_data_ontap, Storagegrid, Communications_cloud_native_core_network_function_cloud_native_environment, Enterprise_manager_base_platform, Http_server, Instantis_enterprisetrack, Peoplesoft_enterprise_peopletools, Zfs_storage_appliance_kit, Ruggedcom_nms, Sinec_nms, Sinema_remote_connect_server, Sinema_server, Tenable\.sc 7.5
2021-10-05 CVE-2021-41524 While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. Http_server, Fedora, Cloud_backup, Instantis_enterprisetrack 7.5
2021-10-05 CVE-2021-41773 A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in... Http_server, Fedora, Cloud_backup, Instantis_enterprisetrack 7.5
2021-03-01 CVE-2021-25329 The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. Tomcat, Debian_linux, Agile_plm, Communications_cloud_native_core_policy, Communications_cloud_native_core_security_edge_protection_proxy, Communications_instant_messaging_server, Database, Graph_server_and_client, Instantis_enterprisetrack, Managed_file_transfer, Mysql_enterprise_monitor, Siebel_ui_framework 7.0
