Apache Tomcat 4.0.3 for Windows allows remote attackers to obtain the web root path via an HTTP request for a resource that does not exist, such as lpt9, which leaks the information in an error message.
Apache Tomcat 4.0.1 allows remote attackers to obtain the web root path via HTTP requests for JSP files preceded by (1) +/, (2) >/, (3) </, and (4) %20/, which leaks the pathname in an error message.
Unknown vulnerability in Apache 1.3.19 running on HP Secure OS for Linux 1.0 allows remote attackers to cause "unexpected results" via an HTTP request.
PHP, when installed on Windows with Apache and ScriptAlias for /php/ set to c:/php/, allows remote attackers to read arbitrary files and possibly execute arbitrary programs via an HTTP request for php.exe with a filename in the query string.
Apache before 1.3.24, when writing to the log file, records a spoofed hostname from the reverse lookup of an IP address, even when a double-reverse lookup fails, which allows remote attackers to hide the original source of activities.
Tomcat 4.0 through 4.1.12, using mod_jk 1.2.1 module on Apache 1.3 through 1.3.27, allows remote attackers to cause a denial of service (desynchronized communications) via an HTTP GET request with a Transfer-Encoding chunked field with invalid values.
A regression error in the Debian distributions of the apache-ssl package (before 1.3.9 on Debian 2.2, and before 1.3.26 on Debian 3.0), for Apache 1.3.27 and earlier, allows local users to read or modify the Apache password file via a symlink attack on temporary files when the administrator runs (1) htpasswd or (2) htdigest, a re-introduction of a vulnerability that was originally identified and addressed by CVE-2001-0131.
The shared memory scoreboard in the HTTP daemon for Apache 1.3.x before 1.3.27 allows any user running as the Apache UID to send a SIGUSR1 signal to any process as root, resulting in a denial of service (process kill) or possibly other behaviors that would not normally be allowed, by modifying the parent[].pid and parent[].last_rtime segments in the scoreboard.
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.
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.
