CVE Hub

The ap_log_rerror function in Apache 2.0 through 2.035, when a CGI application encounters an error, sends error messages to the client that include the full path for the server, which allows remote attackers to obtain sensitive information.

The dbm and shm session cache code in mod_ssl before 2.8.7-1.3.23, and Apache-SSL before 1.3.22+1.46, does not properly initialize memory using the i2d_SSL_SESSION function, which allows remote attackers to use a buffer overflow to execute arbitrary code via a large client certificate that is signed by a trusted Certificate Authority (CA), which produces a large serialized session.

The log files in Apache web server contain information directly supplied by clients and does not filter or quote control characters, which could allow remote attackers to hide HTTP requests and spoof source IP addresses when logs are viewed with UNIX programs such as cat, tail, and grep.

mod_usertrack in Apache 1.3.11 through 1.3.20 generates session ID's using predictable information including host IP address, system time and server process ID, which allows local users to obtain session ID's and bypass authentication when these session ID's are used for authentication.

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.

PHP Apache module 4.0.4 and earlier allows remote attackers to bypass .htaccess access restrictions via a malformed HTTP request on an unrestricted page that causes PHP to use those access controls on the next page that is requested.

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.

htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack.

IBM HTTP Server 1.3.6 (based on Apache) allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a long GET request.

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 (httpd.conf) on SuSE 6.4 includes an alias for the /usr/doc directory, which allows remote attackers to read package documentation and obtain system configuration information via an HTTP request for the /doc/packages URL.

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 default configuration of mod_perl for Apache as installed on Mandrake Linux 6.1 through 7.1 sets the /perl/ directory to be browseable, which allows remote attackers to list the contents of that directory.

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 Snoop servlet in Jakarta Tomcat 3.1 and 3.0 under Apache reveals sensitive system information when a remote attacker requests a nonexistent URL with a .snp extension.

Jakarta Tomcat 3.1 under Apache reveals physical path information when a remote attacker requests a URL that does not exist, which generates an error message that includes the physical path.

Trustix installs the httpsd program for Apache-SSL with world-writeable permissions, which allows local users to replace it with a Trojan horse.

Vulnerability in the mod_vhost_alias virtual hosting module for Apache 1.3.9, 1.3.11 and 1.3.12 allows remote attackers to obtain the source code for CGI programs if the cgi-bin directory is under the document root.

The source.asp example script in the Apache ASP module Apache::ASP 1.93 and earlier allows remote attackers to modify files.

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.

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.

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.

The Apache web server for Win32 may provide access to restricted files when a . (dot) is appended to a requested URL.

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 besides "-->".
