Description:
Ziv Kamir has reported some vulnerabilities in Xerver, which can be exploited by malicious people to conduct cross-site scripting attacks, and disclose system and sensitive information.
1) The problem is that it is possible to disclose the source code of script files by appending a dot to the filename in a HTTP request.
Example:
http://[host]/script.pl.
2) The problem is that the content of a directory can be disclosed even when there is an index file by appending a null character to the path in a HTTP request.
Example:
http://[host]/%00/
This can further be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site via a specially crafted path.
Example:
http://[host]/%00/[code]
The vulnerabilities have been reported in version 4.17. Other versions may also be affected.
Solution:
Update to version 4.20.
