Description:
Two vulnerabilities have been reported in Webmin and Usermin, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose potentially sensitive information.
1) Some input passed in a NULL character ("%00") in the URL isn't properly verified before being used. This can be exploited to disclose the source code of arbitrary CGI and Perl programs.
2) Some input passed in a NULL character ("%00") in the URL isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities have been reported in the following versions:
* Webmin versions prior to 1.296.
* Usermin versions prior to 1.226.
Solution:
