2025-04-29 CVE-2025-3891 A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability. Http_server, Debian_linux, Enterprise_linux N/A
2024-04-04 CVE-2023-38709 Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. Http_server, Macos, Fabric_operating_system, Debian_linux, Fedora, Ontap, Ontap_tools N/A
2024-04-04 CVE-2024-24795 HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue. Http_server, Macos, Fabric_operating_system, Debian_linux, Fedora, Ontap, Ontap_tools N/A
2021-09-16 CVE-2021-40438 A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. Http_server, Brocade_fabric_operating_system_firmware, Debian_linux, F5os, Fedora, Cloud_backup, Clustered_data_ontap, Storagegrid, Enterprise_manager_ops_center, Http_server, Instantis_enterprisetrack, Secure_global_desktop, Zfs_storage_appliance_kit, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_arm_64, Enterprise_linux_for_arm_64_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_ibm_z_systems_eus_s390x, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_update_services_for_sap_solutions, Enterprise_linux_workstation, Jboss_core_services, Software_collections, Rocky_linux, Ruggedcom_nms, Sinec_nms, Sinema_remote_connect_server, Sinema_server, Tenable\.sc 9.0
2020-08-07 CVE-2020-11993 Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. Http_server, Ubuntu_linux, Debian_linux, Fedora, Clustered_data_ontap, Leap, Communications_element_manager, Communications_session_report_manager, Communications_session_route_manager, Enterprise_manager_ops_center, Hyperion_infrastructure_technology, Instantis_enterprisetrack, Zfs_storage_appliance_kit 7.5
2021-08-16 CVE-2021-33193 A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48. Http_server, Debian_linux, Fedora, Secure_backup, Zfs_storage_appliance_kit, Tenable\.sc 7.5
2021-09-16 CVE-2021-36160 A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). 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 7.5
2021-09-16 CVE-2021-39275 ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. Http_server, Debian_linux, Fedora, Cloud_backup, Clustered_data_ontap, Storagegrid, Http_server, Instantis_enterprisetrack, Zfs_storage_appliance_kit, Sinec_nms, Sinema_server 9.8
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
