Cross-site scripting (XSS) vulnerability in Webmin 1.540 and earlier allows local users to inject arbitrary web script or HTML via a chfn command that changes the real (aka Full Name) field, related to useradmin/index.cgi and useradmin/user-lib.pl.

Cross-site scripting (XSS) vulnerability in Webmin before 1.500 and Usermin before 1.430 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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.

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.

The web mail functionality in Usermin 1.x and Webmin 1.x allows remote attackers to execute arbitrary commands via shell metacharacters in an e-mail message.
