1 CVE-2019-10098 601 2019-09-25 2019-10-09
5.8
None Remote Medium Not required Partial Partial None
In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL.
2 CVE-2019-10092 79 XSS 2019-09-26 2019-09-30
4.3
None Remote Medium Not required None Partial None
In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed.
3 CVE-2019-10082 416 2019-09-26 2019-09-27
6.4
None Remote Low Not required Partial None Partial
In Apache HTTP Server 2.4.18-2.4.39, using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown.
4 CVE-2019-10081 119 Overflow 2019-08-15 2019-08-30
5.0
None Remote Low Not required None None Partial
HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client.
5 CVE-2019-0220 399 2019-06-11 2019-06-25
5.0
None Remote Low Not required Partial None None
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.
6 CVE-2019-0211 264 Exec Code 2019-04-08 2019-06-11
7.2
None Local Low Not required Complete Complete Complete
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.
7 CVE-2019-0197 444 2019-06-11 2019-06-17
4.9
None Remote Medium Single system None Partial Partial
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.
8 CVE-2019-0196 416 2019-06-11 2019-06-17
5.0
None Remote Low Not required None None Partial
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.
9 CVE-2018-17199 384 2019-01-30 2019-07-23
5.0
None Remote Low Not required None Partial None
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.
10 CVE-2018-11763 20 2018-09-25 2019-06-11
4.3
None Remote Medium Not required None None Partial
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.
11 CVE-2018-1333 400 DoS 2018-06-18 2019-10-02
5.0
None Remote Low Not required None None Partial
By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33).
12 CVE-2018-1312 287 2018-03-26 2019-07-29
6.8
None Remote Medium Not required Partial Partial Partial
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.
13 CVE-2018-1283 20 2018-03-26 2019-08-15
3.5
None Remote Medium Single system None Partial None
In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.
14 CVE-2017-15715 20 2018-03-26 2019-08-15
6.8
None Remote Medium Not required Partial Partial Partial
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.
15 CVE-2017-15710 787 DoS 2018-03-26 2019-08-15
5.0
None Remote Low Not required None None Partial
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all.
16 CVE-2017-9798 416 2017-09-18 2019-04-23
5.0
None Remote Low Not required Partial None None
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
17 CVE-2017-9788 20 DoS +Info 2017-07-13 2019-08-15
6.4
None Remote Low Not required Partial None Partial
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
18 CVE-2017-7679 119 Overflow 2017-06-19 2018-06-02
7.5
None Remote Low Not required Partial Partial Partial
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.
19 CVE-2017-7668 20 2017-06-19 2018-06-02
7.5
None Remote Low Not required Partial Partial Partial
The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
20 CVE-2017-7659 476 2017-07-26 2018-06-02
5.0
None Remote Low Not required None None Partial
A maliciously constructed HTTP/2 request could cause mod_http2 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process.
21 CVE-2017-3169 476 2017-06-19 2018-06-02
7.5
None Remote Low Not required Partial Partial Partial
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
22 CVE-2017-3167 287 Bypass 2017-06-19 2018-06-02
7.5
None Remote Low Not required Partial Partial Partial
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
