CVE-2021-40438 | 9 Apache, Broadcom, Debian and 6 more | 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more | 2025-02-06 | 6.8 MEDIUM | 9.0 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-2019-0211 | 8 Apache, Canonical, Debian and 5 more | 27 Http Server, Ubuntu Linux, Debian Linux and 24 more | 2025-02-06 | 7.2 HIGH | 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-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 5 Http Server, Fedora, Cloud Backup and 2 more | 2025-02-04 | 7.5 HIGH | 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-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2025-02-04 | 4.3 MEDIUM | 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-2007-4465 | 1 Apache | 1 Http Server | 2025-01-17 | 4.3 MEDIUM | 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 | 1 Apache | 1 Http Server | 2025-01-16 | 4.6 MEDIUM | 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 | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2025-01-14 | 7.8 HIGH | 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 | 2 Apache, Netapp | 2 Http Server, Clustered Data Ontap | 2024-12-02 | N/A | 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 | 2 Apache, Microsoft | 2 Http Server, Windows | 2024-11-21 | N/A | 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 | N/A | 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 | 2 Apache, Netapp | 2 Http Server, Clustered Data Ontap | 2024-11-21 | N/A | 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 | 2 Apache, Netapp | 2 Http Server, Clustered Data Ontap | 2024-11-21 | N/A | 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 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Ontap | 2024-11-21 | N/A | 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 | 3 Apache, Debian, Fedoraproject | 3 Http Server, Debian Linux, Fedora | 2024-11-21 | N/A | 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 | 1 Apache | 1 Http Server | 2024-11-21 | N/A | 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-2023-31122 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2024-11-21 | N/A | 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 | 3 Apache, Debian, Unbit | 3 Http Server, Debian Linux, Uwsgi | 2024-11-21 | N/A | 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 | 1 Apache | 1 Http Server | 2024-11-21 | N/A | 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 | 1 Apache | 1 Http Server | 2024-11-21 | N/A | 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 | 1 Apache | 1 Http Server | 2024-11-21 | N/A | 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. |
