Apache HTTP Server .var file request could disclose installation path
|apache-var-path-disclosure (9875)||Low Risk|
Apache HTTP Server could allow a remote attacker to obtain the full path to the Apache installation directory, caused by a vulnerability in the multiview type map negotiation. If a remote attacker sends a specially-crafted URL request appended with .var, the attacker could cause an error message to be returned that would contain the full path to the installation directory. An attacker could use this vulnerability to obtain sensitive information, such as the operating system and server version. This information could then be used to launch further attacks against the affected Web server.
Note: This vulnerability only affects non-Unix installations of Apache HTTP Server.
Upgrade to the latest version of Apache HTTP Server (2.0.40 or later), available from the Apache Web site. See References.

- CVE-2002-0654: Apache 2.0 through 2.0.39 on Windows, OS2, and Netware allows remote attackers to determine the full pathname of the server via (1) a request for a .var file, which leaks the pathname in the resulting error message, or (2) via an error message that occurs when a script (child process) cannot be invoked.
