** DISPUTED ** The Apache HTTP Server, when accessed through a TCP connection with a large window size, allows remote attackers to cause a denial of service (network bandwidth consumption) via a Range header that specifies multiple copies of the same fragment. NOTE: the severity of this issue has been disputed by third parties, who state that the large window size required by the attack is not normally supported or configured by the server, or that a DDoS-style attack would accomplish the same goal.
CVE-2009-3555 7 Apache, Canonical, Debian and 4 more 7 Http Server, Ubuntu Linux, Debian Linux and 4 more 2021-02-05 5.8 MEDIUM N/A

The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk Multi-Processing Module 2.2.11-01 and 2.2.11-02 for the Apache HTTP Server does not properly handle certain configuration sections that specify NiceValue but not AssignUserID, which might allow remote attackers to gain privileges by leveraging the root uid and root gid of an mpm-itk process.

** DISPUTED ** The mod_php module for the Apache HTTP Server allows local users with write access to PHP scripts to send signals to the server's process group and use the server's file descriptors, as demonstrated by sending a STOP signal, then intercepting incoming connections on the server's TCP port. NOTE: the PHP developer has disputed this vulnerability, saying "The opened file descriptors are opened by Apache. It is the job of Apache to protect them ... Not a bug in PHP."
CVE-2006-4110 1 Apache 1 Http Server 2018-10-17 4.3 MEDIUM N/A
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.
CVE-2007-3303 1 Apache 1 Http Server 2018-10-16 4.9 MEDIUM N/A
Apache httpd 2.0.59 and 2.2.4, with the Prefork MPM module, allows local users to cause a denial of service via certain code sequences executed in a worker process that (1) stop request processing by killing all worker processes and preventing creation of replacements or (2) hang the system by forcing the master process to fork an arbitrarily large number of worker processes. NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.
CVE-2007-6514 2 Apache, Linux 2 Http Server, Linux Kernel 2018-10-15 4.3 MEDIUM N/A
Apache HTTP Server, when running on Linux with a document root on a Windows share mounted using smbfs, allows remote attackers to obtain unprocessed content such as source files for .php programs via a trailing "\" (backslash), which is not handled by the intended AddType directive.
CVE-2007-6203 1 Apache 1 Http Server 2018-10-15 4.3 MEDIUM N/A
Apache HTTP Server 2.0.x and 2.2.x does not sanitize the HTTP Method specifier header from an HTTP request when it is reflected back in a "413 Request Entity Too Large" error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated via an HTTP request containing an invalid Content-length value, a similar issue to CVE-2006-3918.
CVE-2009-0796 1 Apache 2 Http Server, Mod Perl 2018-10-10 2.6 LOW N/A

CVE-2011-1928 1 Apache 2 Apr-util, Http Server 2018-01-06 4.3 MEDIUM N/A
The fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library 1.4.3 and 1.4.4, and the Apache HTTP Server 2.2.18, allows remote attackers to cause a denial of service (infinite loop) via a URI that does not match unspecified types of wildcard patterns, as demonstrated by attacks against mod_autoindex in httpd when a /*/WEB-INF/ configuration pattern is used. NOTE: this issue exists because of an incorrect fix for CVE-2011-0419.
CVE-2011-3639 1 Apache 10 Http Server, Http Server2.0a1, Http Server2.0a2 and 7 more 2017-12-29 4.3 MEDIUM N/A
The mod_proxy module in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x before 2.2.18, when the Revision 1179239 patch is in place, does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers by using the HTTP/0.9 protocol with a malformed URI containing an initial @ (at sign) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.
CVE-2014-3250 3 Apache, Puppet, Redhat 3 Http Server, Puppet, Linux 2017-12-27 4.0 MEDIUM 6.5 MEDIUM

CVE-2003-1418 1 Apache 1 Http Server 2017-10-20 4.3 MEDIUM N/A
Apache HTTP Server 1.3.22 through 1.3.27 on OpenBSD allows remote attackers to obtain sensitive information via (1) the ETag header, which reveals the inode number, or (2) multipart MIME boundary, which reveals child process IDs (PID).
CVE-2004-0173 1 Apache 1 Http Server 2017-10-10 5.0 MEDIUM N/A
Directory traversal vulnerability in Apache 1.3.29 and earlier, and Apache 2.0.48 and earlier, when running on Cygwin, allows remote attackers to read arbitrary files via a URL containing "..%5C" (dot dot encoded backslash) sequences.

PHP 4.3.4 and earlier in Apache 1.x and 2.x (mod_php) can leak global variables between virtual hosts that are handled by the same Apache child process but have different settings, which could allow remote attackers to obtain sensitive information.
CVE-2000-0868 2 Apache, Suse 2 Http Server, Suse Linux 2017-10-10 5.0 MEDIUM N/A
The default configuration of Apache 1.3.12 in SuSE Linux 6.4 allows remote attackers to read source code for CGI scripts by replacing the /cgi-bin/ in the requested URL with /cgi-bin-sdb/.
CVE-2001-0042 1 Apache 1 Http Server 2017-10-10 5.0 MEDIUM N/A
PHP 3.x (PHP3) on Apache 1.3.6 allows remote attackers to read arbitrary files via a modified .. (dot dot) attack containing "%5c" (encoded backslash) sequences.
CVE-2001-1072 1 Apache 1 Http Server 2017-10-10 5.0 MEDIUM N/A
Apache with mod_rewrite enabled on most UNIX systems allows remote attackers to bypass RewriteRules by inserting extra / (slash) characters into the requested path, which causes the regular expression in the RewriteRule to fail.
CVE-2000-0869 2 Apache, Suse 2 Http Server, Suse Linux 2017-10-10 5.0 MEDIUM N/A
The default configuration of Apache 1.3.12 in SuSE Linux 6.4 enables WebDAV, which allows remote attackers to list arbitrary directories via the PROPFIND HTTP request method.
CVE-2012-3526 2 Apache, Thomas Eibner 2 Http Server, Mod Rpaf 2017-08-29 5.0 MEDIUM N/A
The reverse proxy add forward module (mod_rpaf) 0.5 and 0.6 for the Apache HTTP Server allows remote attackers to cause a denial of service (server or application crash) via multiple X-Forwarded-For headers in a request.
CVE-2012-1181 1 Apache 2 Http Server, Mod Fcgid 2017-08-29 5.0 MEDIUM N/A
fcgid_spawn_ctl.c in the mod_fcgid module 2.3.6 for the Apache HTTP Server does not recognize the FcgidMaxProcessesPerClass directive for a virtual host, which makes it easier for remote attackers to cause a denial of service (memory consumption) via a series of HTTP requests that triggers a process count higher than the intended limit.
CVE-2007-1741 1 Apache 1 Http Server 2017-07-29 6.2 MEDIUM N/A
Multiple race conditions in suexec in Apache HTTP Server (httpd) 2.2.3 between directory and file validation, and their usage, allow local users to gain privileges and execute arbitrary code by renaming directories or performing symlink attacks. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root."
