Date Id Summary Products Score Patch Annotated
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 7.5
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
2022-03-14 CVE-2022-23943 Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions. Http_server, Debian_linux, Fedora, Http_server, Zfs_storage_appliance_kit 9.8
2022-06-09 CVE-2022-26377 Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions. Http_server, Fedora, Clustered_data_ontap 7.5
2022-06-09 CVE-2022-28615 Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected. Http_server, Fedora, Clustered_data_ontap 9.1
