CVE-2014-0118 3 Apache, Debian, Redhat 4 Http Server, Debian Linux, Enterprise Linux and 1 more 2022-09-14 4.3 MEDIUM N/A
The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size.
CVE-2014-0226 4 Apache, Debian, Oracle and 1 more 7 Http Server, Debian Linux, Enterprise Manager Ops Center and 4 more 2022-09-14 6.8 MEDIUM N/A
Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c.
CVE-2018-1312 5 Apache, Canonical, Debian and 2 more 14 Http Server, Ubuntu Linux, Debian Linux and 11 more 2022-09-07 6.8 MEDIUM 9.8 CRITICAL
In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.
CVE-2016-5387 8 Apache, Canonical, Debian and 5 more 21 Http Server, Ubuntu Linux, Debian Linux and 18 more 2022-09-07 6.8 MEDIUM 8.1 HIGH
The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.
CVE-2016-8743 4 Apache, Debian, Netapp and 1 more 12 Http Server, Debian Linux, Clustered Data Ontap and 9 more 2022-09-07 5.0 MEDIUM 7.5 HIGH
Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution.
CVE-2019-0197 6 Apache, Canonical, Fedoraproject and 3 more 12 Http Server, Ubuntu Linux, Fedora and 9 more 2022-09-07 4.9 MEDIUM 4.2 MEDIUM
A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue.
CVE-2022-30522 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-09-07 5.0 MEDIUM 7.5 HIGH
If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
CVE-2014-3581 4 Apache, Canonical, Oracle and 1 more 9 Http Server, Ubuntu Linux, Enterprise Manager Ops Center and 6 more 2022-09-07 5.0 MEDIUM N/A
The cache_merge_headers_out function in modules/cache/cache_util.c in the mod_cache module in the Apache HTTP Server before 2.4.11 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty HTTP Content-Type header.
CVE-2022-26377 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-24 5.0 MEDIUM 7.5 HIGH
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.
CVE-2022-28614 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-24 5.0 MEDIUM 5.3 MEDIUM
The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against current headers to resolve the issue.
CVE-2022-28615 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-24 6.4 MEDIUM 9.1 CRITICAL
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.
CVE-2022-29404 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-24 5.0 MEDIUM 7.5 HIGH
In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0) may cause a denial of service due to no default limit on possible input size.
CVE-2022-31813 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-19 7.5 HIGH 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 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2022-08-19 5.0 MEDIUM 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.
CVE-1999-0289 2 Apache, Microsoft 2 Http Server, Windows 2022-08-17 5.0 MEDIUM N/A
The Apache web server for Win32 may provide access to restricted files when a . (dot) is appended to a requested URL.
CVE-1999-0107 1 Apache 1 Http Server 2022-08-17 5.0 MEDIUM N/A
Buffer overflow in Apache 1.2.5 and earlier allows a remote attacker to cause a denial of service with a large number of GET requests containing a large number of / characters.
CVE-1999-0071 1 Apache 1 Http Server 2022-08-17 7.5 HIGH N/A
Apache httpd cookie buffer overflow for versions 1.1.1 and earlier.
CVE-1999-0045 2 Apache, Netscape 4 Http Server, Commerce Server, Communications Server and 1 more 2022-08-17 7.5 HIGH N/A
List of arbitrary files on Web host via nph-test-cgi script.
CVE-1999-0236 2 Apache, Illinois 2 Http Server, Ncsa Httpd 2022-08-17 5.0 MEDIUM 7.5 HIGH
ScriptAlias directory in NCSA and Apache httpd allowed attackers to read CGI programs.
CVE-2020-1927 8 Apache, Broadcom, Canonical and 5 more 14 Http Server, Brocade Fabric Operating System, Ubuntu Linux and 11 more 2022-07-25 5.8 MEDIUM 6.1 MEDIUM
In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.
