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.
Apache before 1.3.20 on Windows and OS/2 systems allows remote attackers to cause a denial of service (GPF) via an HTTP request for a URI that contains a large number of / (slash) or other characters, which causes certain functions to dereference a null pointer.
Apache 1.3.20 with Multiviews enabled allows remote attackers to view directory contents and bypass the index page via a URL containing the "M=D" query string.
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, (...
PHP for Windows, when installed on Apache 2.0.28 beta as a standalone CGI module, allows remote attackers to obtain the physical path of the php.exe via a request with malformed arguments such as /123, which leaks the pathname in the error message.
PHP, when installed with Apache and configured to search for index.php as a default web page, allows remote attackers to obtain the full pathname of the server via the HTTP OPTIONS method, which reveals the pathname in the resulting error message.
split-logfile in Apache 1.3.20 allows remote attackers to overwrite arbitrary files that end in the .log extension via an HTTP request with a / (slash) in the Host: header.
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...
Apache 1.3.20 on Windows servers allows remote attackers to bypass the default index page and list directory contents via a URL with a large number of / (slash) characters.
Apache on MacOS X Client 10.0.3 with the HFS+ file system allows remote attackers to bypass access restrictions via a URL that contains some characters whose case is not matched by Apache's filters.
mod_proxy in Apache 1.2.5 and earlier allows remote attackers to cause a denial of service via malformed FTP commands, which causes Apache to dump core.
Apache allows remote attackers to conduct a denial of service via a large number of MIME headers.
Multiple buffer overflows in smbvalid/smbval SMB authentication library, as used in Apache::AuthenSmb and possibly other modules, allows remote attackers to execute arbitrary commands via (1) a long username, (2) a long password, and (3) other unspecified methods.
A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes.
guestbook.pl cleanses user-inserted SSI commands by removing text between "<!--" and "-->" separators, which allows remote attackers to execute arbitrary commands when guestbook.pl is run on Apache 1.3.9 and possibly other versions, since Apache allows other closing sequences bes...
htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack.
mod_rewrite in Apache 1.3.12 and earlier allows remote attackers to read arbitrary files if a RewriteRule directive is expanded to include a filename whose name contains a regular expression.
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/.
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.
The Apache 1.3.x HTTP server for Windows platforms allows remote attackers to list directory contents by requesting a URL containing a large number of / characters.
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.
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.
