Multiple cross-site scripting (XSS) vulnerabilities in chooser.cgi in Webmin before 1.330 and Usermin before 1.260 allow remote attackers to inject arbitrary web script or HTML via a crafted filename.
Usermin before 1.220 (20060629) allows remote attackers to read arbitrary files, possibly related to chfn/save.cgi not properly handling an empty shell parameter, which results in changing root's shell instead of the shell of a specified user.
Webmin before 1.296 and Usermin before 1.226 do not properly handle a URL with a null ("%00") character, which allows remote attackers to conduct cross-site scripting (XSS), read CGI program source code, list directories, and possibly execute programs.
Unknown vulnerability in (1) Webmin and (2) Usermin before 1.200 causes Webmin to change permissions and ownership of configuration files, with unknown impact.
