CVE-2019-0211 8 Apache, Canonical, Debian and 5 more 28 Http Server, Ubuntu Linux, Debian Linux and 25 more 2025-01-23 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-2007-4465 2 Apache, Redhat 6 Http Server, Certificate System, Enterprise Linux and 3 more 2025-01-17 6.1 Medium
Cross-site scripting (XSS) vulnerability in mod_autoindex.c in the Apache HTTP Server before 2.2.6, when the charset on a server-generated page is not defined, allows remote attackers to inject arbitrary web script or HTML via the P parameter using the UTF-7 charset. NOTE: it could be argued that this issue is due to a design limitation of browsers that attempt to perform automatic content type detection.
CVE-2004-0747 2 Apache, Redhat 2 Http Server, Enterprise Linux 2025-01-16 7.8 High
Buffer overflow in Apache 2.0.50 and earlier allows local users to gain apache privileges via a .htaccess file that causes the overflow during expansion of environment variables.
CVE-2019-9517 12 Apache, Apple, Canonical and 9 more 28 Http Server, Traffic Server, Mac Os X and 25 more 2025-01-14 7.5 High
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.
CVE-2024-38476 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2024-12-02 9.8 Critical
Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue.
CVE-2024-40898 3 Apache, Microsoft, Redhat 3 Http Server, Windows, Jboss Core Services 2024-11-21 7.5 High
SSRF in Apache HTTP Server on Windows with mod_rewrite in server/vhost context, allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests. Users are recommended to upgrade to version 2.4.62 which fixes this issue. 
CVE-2024-40725 1 Apache 1 Http Server 2024-11-21 5.3 Medium
A partial fix for  CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 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 2.4.62, which fixes this issue.
CVE-2024-38477 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2024-11-21 7.5 High
null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash the server via a malicious request. Users are recommended to upgrade to version 2.4.60, which fixes this issue.
CVE-2024-38474 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2024-11-21 9.8 Critical
Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag "UnsafeAllow3F" is specified.
CVE-2024-27316 4 Apache, Fedoraproject, Netapp and 1 more 7 Http Server, Fedora, Ontap and 4 more 2024-11-21 7.5 High
HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
CVE-2023-45802 4 Apache, Debian, Fedoraproject and 1 more 6 Http Server, Debian Linux, Fedora and 3 more 2024-11-21 5.9 Medium
When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During "normal" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out. Users are recommended to upgrade to version 2.4.58, which fixes the issue.
CVE-2023-43622 2 Apache, Redhat 2 Http Server, Enterprise Linux 2024-11-21 7.5 High
An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the server, similar to the well known "slow loris" attack pattern. This has been fixed in version 2.4.58, so that such connection are terminated properly after the configured connection timeout. This issue affects Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which fixes the issue.
CVE-2023-38709 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2024-11-21 7.3 High
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.
CVE-2023-31122 3 Apache, Fedoraproject, Redhat 4 Http Server, Fedora, Enterprise Linux and 1 more 2024-11-21 7.5 High
Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server: through 2.4.57.
CVE-2023-27522 4 Apache, Debian, Redhat and 1 more 6 Http Server, Debian Linux, Enterprise Linux and 3 more 2024-11-21 7.5 High
HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can truncate/split the response forwarded to the client.
CVE-2023-25690 2 Apache, Redhat 8 Http Server, Enterprise Linux, Jboss Core Services and 5 more 2024-11-21 9.8 Critical
Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
CVE-2022-37436 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2024-11-21 5.3 Medium
Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client.
CVE-2022-36760 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2024-11-21 9.0 Critical
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 2.4.54 and prior versions.
CVE-2022-31813 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Clustered Data Ontap and 3 more 2024-11-21 9.8 Critical
Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application.
CVE-2022-30556 4 Apache, Fedoraproject, Netapp and 1 more 5 Http Server, Fedora, Clustered Data Ontap and 2 more 2024-11-21 7.5 High
Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.
