Buffer overflows in the ApacheBench benchmark support program (ab.c) in Apache before 1.3.27, and Apache 2.x before 2.0.43, allow a malicious web server to cause a denial of service and possibly execute arbitrary code via a long response.
Apache 1.3 through 1.3.24, and Apache 2.0 through 2.0.36, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a chunk-encoded HTTP request that causes Apache to use an incorrect size.
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.
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.
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.
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.
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 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.
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.
