There is a vulnerability in Apache 2.0 through 2.035 that could disclose the real path to a CGI script or other file.


A vulnerability in the Apache web server could disclose sensitive information. Quoting from the Apache Change Log:

*) [Security] Added the APLOG_TOCLIENT flag to ap_log_rerror() to explicitly tell the server that warning messages should be sent to the client in addition to being recorded in the error log. Prior to this change, ap_log_rerror() always sent warning messages to the client. In one case, a faulty CGI script caused the server to send a warning message to the client that contained the full path to the CGI script. This could be considered a minor security exposure. [Bill Stoddard]

This vulnerability may disclose sensitive information.


Sensitive information may be disclosed.


if you are running version 2.0, upgrade to Apache 2.036 or later.
