CVSS v3.1 |
| Off-by-one error in the ldap scheme handling in the Rewrite module (mod_rewrite) in Apache 1.3 from 1.3.28, 2.0.46 and other versions before 2.0.59, and 2.2, when RewriteEngine is enabled, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted URLs that are not properly handled using certain rewrite rules. |
| Apache 2.2.2, when running on Windows, allows remote attackers to read source code of CGI programs via a request that contains uppercase (or alternate case) characters that bypass the case-sensitive ScriptAlias directive, but allow access to the file on case-insensitive file systems. |
| The Apache web server for Win32 may provide access to restricted files when a . (dot) is appended to a requested URL. |
| A default configuration of Apache on Debian GNU/Linux sets the ServerRoot to /usr/doc, which allows remote users to read documentation files for the entire server. |
| Apache WWW server 1.3.1 and earlier allows remote attackers to cause a denial of service (resource exhaustion) via a large number of MIME headers with the same name, aka the "sioux" vulnerability. |
| Cross site scripting vulnerabilities in Apache 1.3.0 through 1.3.11 allow remote attackers to execute script as other web site visitors via (1) the printenv CGI (printenv.pl), which does not encode its output, (2) pages generated by the ap_send_error_response function such as a default 404, which does not add an explicit charset, or (3) various messages that are generated by certain Apache modules or core code. NOTE: the printenv issue might still exist for web browsers that can render text/plain content types as HTML, such as Internet Explorer, but CVE regards this as a design limitation of those browsers, not Apache. The printenv.pl/acuparam vector, discloser on 20070724, is one such variant. |
| The default installation of Apache before 1.3.19 allows remote attackers to list directories instead of the multiview index.html file via an HTTP request for a path that contains many / (slash) characters, which causes the path to be mishandled by (1) mod_negotiation, (2) mod_dir, or (3) mod_autoindex. |
| The default installation of Apache before 1.3.19 on Mandrake Linux 7.1 through 8.0 and Linux Corporate Server 1.0.1 allows remote attackers to list the directory index of arbitrary web directories. |
| Apache for Win32 before 1.3.24, and 2.0.x before 2.0.34-beta, allows remote attackers to execute arbitrary commands via shell metacharacters (a | pipe character) provided as arguments to batch (.bat) or .cmd scripts, which are sent unfiltered to the shell interpreter, typically cmd.exe. |
| Cross-site scripting vulnerability in auction.pl of MakeBid Auction Deluxe 3.30 allows remote attackers to obtain information from other users via the form fields (1) TITLE, (2) DESCTIT, (3) DESC, (4) searchstring, (5) ALIAS, (6) EMAIL, (7) ADDRESS1, (8) ADDRESS2, (9) ADDRESS3, (10) PHONE1, (11) PHONE2, (12) PHONE3, or (13) PHONE4. |
| Cross-site scripting (XSS) vulnerability in the default error page of Apache 2.0 before 2.0.43, and 1.3.x up to 1.3.26, when UseCanonicalName is "Off" and support for wildcard DNS is present, allows remote attackers to execute script as other web page visitors via the Host: header, a different vulnerability than CAN-2002-1157. |
| Apache before 2.0.44, when running on unpatched Windows 9x and Me operating systems, allows remote attackers to cause a denial of service or execute arbitrary code via an HTTP request containing MS-DOS device names. |
| Apache 1.3 before 1.3.25 and Apache 2.0 before version 2.0.46 does not filter terminal escape sequences from its access logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences, a different vulnerability than CVE-2003-0020. |
| In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by trusted clients is possible using TLS 1.3 session resumption.
Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host. |
| Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi) passes the shell-escaped query string to #exec cmd="..." directives.
This issue affects Apache HTTP Server before 2.4.66.
Users are recommended to upgrade to version 2.4.66, which fixes the issue. |
| 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. |
| 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. |
| 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. |
| Server-Side Request Forgery (SSRF) vulnerability
in Apache HTTP Server on Windows
with AllowEncodedSlashes On and MergeSlashes Off allows to potentially leak NTLM
hashes to a malicious server via SSRF and malicious requests or content
Users are recommended to upgrade to version 2.4.66, which fixes the issue. |
| Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache HTTP Server through environment variables set via the Apache configuration unexpectedly superseding variables calculated by the server for CGI programs.
This issue affects Apache HTTP Server from 2.4.0 through 2.4.65.
Users are recommended to upgrade to version 2.4.66 which fixes the issue. |
