CVE-2003-0189 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.
CVE-2003-0789 1 Apache 1 Http Server 2021-06-06 10.0 HIGH N/A
mod_cgid in Apache before 2.0.48, when using a threaded MPM, does not properly handle CGI redirect paths, which could cause Apache to send the output of a CGI program to the wrong client.

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 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 via a malformed URI containing an initial @ (at sign) character.

mod_ssl in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (CPU consumption) by aborting an SSL connection in a way that causes an Apache child process to enter an infinite loop.
CVE-2004-0747 1 Apache 1 Http Server 2021-06-06 4.6 MEDIUM N/A
Buffer overflow in Apache 2.0.50 and earlier allows local users to gain apache privileges via a .htaccess file that causes the overflow during expansion of environment variables.
CVE-2000-1205 1 Apache 1 Http Server 2021-06-06 4.3 MEDIUM N/A
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.
CVE-2010-2791 2 Apache, Unix 2 Http Server, Unix 2021-06-06 5.0 MEDIUM N/A
mod_proxy in httpd in Apache HTTP Server 2.2.9, when running on Unix, does not close the backend connection if a timeout occurs when reading a response from a persistent connection, which allows remote attackers to obtain a potentially sensitive response intended for a different client in opportunistic circumstances via a normal HTTP request. NOTE: this is the same issue as CVE-2010-2068, but for a different OS and set of affected versions.
CVE-2013-4352 1 Apache 1 Http Server 2021-06-06 4.3 MEDIUM N/A
The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value.
CVE-2011-4317 1 Apache 1 Http Server 2021-06-06 4.3 MEDIUM N/A
The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21, 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 via a malformed URI containing an @ (at sign) character and a : (colon) character in invalid positions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.
CVE-2004-0493 5 Apache, Avaya, Gentoo and 2 more 8 Http Server, Converged Communications Server, S8300 and 5 more 2021-06-06 6.4 MEDIUM N/A
The ap_get_mime_headers_core function in Apache httpd 2.0.49 allows remote attackers to cause a denial of service (memory exhaustion), and possibly an integer signedness error leading to a heap-based buffer overflow on 64 bit systems, via long header lines with large numbers of space or tab characters.

CVE-2002-0840 2 Apache, Oracle 5 Http Server, Application Server, Database Server and 2 more 2021-06-06 6.8 MEDIUM N/A
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.
