|---|---|---|---|---|
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2024-08-04 | 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-2019-0220 | 6 Apache, Canonical, Debian and 3 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2024-08-04 | N/A |
| A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them. | ||||
| CVE-2019-0211 | 8 Apache, Canonical, Debian and 5 more | 28 Http Server, Ubuntu Linux, Debian Linux and 25 more | 2024-08-04 | 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-2019-0217 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-08-04 | 7.5 High |
| In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions. | ||||
| CVE-2019-0215 | 3 Apache, Fedoraproject, Redhat | 3 Http Server, Fedora, Enterprise Linux | 2024-08-04 | N/A |
| In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions. | ||||
| CVE-2019-0196 | 4 Apache, Canonical, Debian and 1 more | 5 Http Server, Ubuntu Linux, Debian Linux and 2 more | 2024-08-04 | N/A |
| A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly. | ||||
| CVE-2019-0197 | 6 Apache, Canonical, Fedoraproject and 3 more | 12 Http Server, Ubuntu Linux, Fedora and 9 more | 2024-08-04 | 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-2020-35452 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-08-04 | 7.3 High |
| Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow | ||||
| CVE-2020-13950 | 5 Apache, Debian, Fedoraproject and 2 more | 8 Http Server, Debian Linux, Fedora and 5 more | 2024-08-04 | 7.5 High |
| Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service | ||||
| CVE-2020-13938 | 4 Apache, Mcafee, Microsoft and 1 more | 4 Http Server, Epolicy Orchestrator, Windows and 1 more | 2024-08-04 | 5.5 Medium |
| Apache HTTP Server versions 2.4.0 to 2.4.46 Unprivileged local users can stop httpd on Windows | ||||
| CVE-2020-11985 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Rhel Software Collections | 2024-08-04 | 5.3 Medium |
| IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. | ||||
| CVE-2020-11984 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-08-04 | 9.8 Critical |
| Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE | ||||
| CVE-2020-11993 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-08-04 | 7.5 High |
| Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. | ||||
| CVE-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 28 Http Server, Ubuntu Linux, Debian Linux and 25 more | 2024-08-04 | 7.5 High |
| Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | ||||
| CVE-2020-1934 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-08-04 | 5.3 Medium |
| In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. | ||||
| CVE-2020-1927 | 9 Apache, Broadcom, Canonical and 6 more | 17 Http Server, Brocade Fabric Operating System, Ubuntu Linux and 14 more | 2024-08-04 | 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. | ||||
| CVE-2021-44790 | 8 Apache, Apple, Debian and 5 more | 20 Http Server, Mac Os X, Macos and 17 more | 2024-08-04 | 9.8 Critical |
| A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. | ||||
| CVE-2021-44224 | 7 Apache, Apple, Debian and 4 more | 15 Http Server, Mac Os X, Macos and 12 more | 2024-08-04 | 8.2 High |
| A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). | ||||
| CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Cloud Backup and 3 more | 2024-08-04 | 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 | 2024-08-04 | 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. | ||||
