| CVE-2019-0211 | 8 Apache, Canonical, Debian and 5 more | 28 Http Server, Ubuntu Linux, Debian Linux and 25 more | 2025-07-28 | 7.8 High |
| In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. | ||||
| CVE-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2025-07-28 | 7.5 High |
| 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 the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013. | ||||
| CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Cloud Backup and 3 more | 2025-07-28 | 9.8 Critical |
| It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. 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 only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions. | ||||
| CVE-2021-40438 | 11 Apache, Broadcom, Debian and 8 more | 45 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 42 more | 2025-07-28 | 9 Critical |
| 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. | ||||
| CVE-2024-38475 | 3 Apache, Netapp, Redhat | 9 Http Server, Ontap 9, Enterprise Linux and 6 more | 2025-07-28 | 9.1 Critical |
| Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained. | ||||
| CVE-2025-3891 | 3 Apache, Debian, Redhat | 7 Http Server, Debian Linux, Enterprise Linux and 4 more | 2025-07-28 | 7.5 High |
| 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. | ||||
| CVE-2025-54090 | 1 Apache | 1 Http Server | 2025-07-27 | 6.3 Medium |
| A bug in Apache HTTP Server 2.4.64 results in all "RewriteCond expr ..." tests evaluating as "true". Users are recommended to upgrade to version 2.4.65, which fixes the issue. | ||||
| CVE-2010-0425 | 5 Apache, Broadcom, Ibm and 2 more | 6 Http Server, Vmware Ace Management Server, Http Server and 3 more | 2025-07-24 | N/A |
| modules/arch/win32/mod_isapi.c in mod_isapi in the Apache HTTP Server 2.0.37 through 2.0.63, 2.2.0 through 2.2.14, and 2.3.x before 2.3.7, when running on Windows, does not ensure that request processing is complete before calling isapi_unload for an ISAPI .dll module, which allows remote attackers to execute arbitrary code via unspecified vectors related to a crafted request, a reset packet, and "orphaned callback pointers." | ||||
| CVE-2024-43204 | 2 Apache, Apache Software Foundation | 2 Http Server, Apache Http Server | 2025-07-15 | 7.5 High |
| SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker. Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request. Users are recommended to upgrade to version 2.4.64 which fixes this issue. | ||||
| CVE-2024-36387 | 3 Apache, Netapp, Redhat | 4 Http Server, Ontap, Enterprise Linux and 1 more | 2025-07-10 | 5.4 Medium |
| Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference, leading to a crash of the server process, degrading performance. | ||||
| CVE-2024-39884 | 2 Apache, Netapp | 2 Http Server, Ontap Tools | 2025-07-01 | 6.2 Medium |
| A regression in the core of Apache HTTP Server 2.4.60 ignores some use of the legacy content-type based configuration of handlers. "AddType" and similar configuration, under some circumstances where files are requested indirectly, result in source code disclosure of local content. For example, PHP scripts may be served instead of interpreted. Users are recommended to upgrade to version 2.4.61, which fixes this issue. | ||||
| CVE-2024-39573 | 3 Apache, Netapp, Redhat | 5 Http Server, Ontap, Enterprise Linux and 2 more | 2025-07-01 | 7.5 High |
| Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy. Users are recommended to upgrade to version 2.4.60, which fixes this issue. | ||||
| CVE-2024-38473 | 4 Apache, Apache Software Foundation, Netapp and 1 more | 6 Http Server, Apache Http Server, Ontap and 3 more | 2025-07-01 | 8.1 High |
| Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests. Users are recommended to upgrade to version 2.4.60, which fixes this issue. | ||||
| CVE-2024-38472 | 4 Apache, Apache Software Foundation, Netapp and 1 more | 4 Http Server, Apache Http Server, Ontap and 1 more | 2025-07-01 | 7.5 High |
| SSRF in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.60 which fixes this issue. Note: Existing configurations that access UNC paths will have to configure new directive "UNCList" to allow access during request processing. | ||||
| CVE-2023-38709 | 7 Apache, Apple, Broadcom and 4 more | 9 Http Server, Macos, Fabric Operating System and 6 more | 2025-06-30 | 7.3 High |
