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-2024-38477 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2025-02-13 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-2024-38476 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2025-02-13 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-2024-38475 3 Apache, Netapp, Redhat 9 Http Server, Ontap 9, Enterprise Linux and 6 more 2025-02-13 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-2024-38474 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2025-02-13 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 2025-02-13 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-2023-43622 2 Apache, Redhat 2 Http Server, Enterprise Linux 2025-02-13 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 3 Apache, Fedoraproject, Redhat 4 Http Server, Fedora, Enterprise Linux and 1 more 2025-02-13 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 2025-02-13 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 2025-02-13 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-2006-20001 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2025-02-13 7.5 High
A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. This issue affects Apache HTTP Server 2.4.54 and earlier.
CVE-2023-38709 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2025-02-13 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-2022-37436 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Core Services 2025-02-13 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 2025-02-13 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-2021-40438 10 Apache, Broadcom, Debian and 7 more 25 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 22 more 2025-02-06 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-2019-0211 8 Apache, Canonical, Debian and 5 more 28 Http Server, Ubuntu Linux, Debian Linux and 25 more 2025-02-06 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 6 Http Server, Fedora, Cloud Backup and 3 more 2025-02-04 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 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 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.
