CSRF exists in Webmin 1.850. By sending a GET request to at/create_job.cgi containing dir=/&cmd= in the URI, an attacker to execute arbitrary commands.
Webmin before 1.860 has XSS with resultant remote code execution. Under the 'Others/File Manager' menu, there is a 'Download from remote URL' option to download a file from a remote server. After setting up a malicious server, one can wait for a file download request and then send an XSS payload that will lead to Remote Code Execution, as demonstrated by an OS command in the value attribute of a name='cmd' input element.
Multiple Cross-site scripting (XSS) vulnerabilities in Webmin before 1.850 allow remote attackers to inject arbitrary web script or HTML via the sec parameter to view_man.cgi, the referers parameter to change_referers.cgi, or the name parameter to save_user.cgi. NOTE: these issues were not fixed in 1.840.
Multiple cross-site scripting vulnerabilities in Webmin versions prior to 1.830 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Cross-site scripting (XSS) vulnerability in Webmin before 1.690 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors. NOTE: this might overlap CVE-2014-3924.
Cross-site scripting (XSS) vulnerability in Webmin before 1.690, when referrer checking is disabled, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: this might overlap CVE-2014-3924.
Multiple cross-site scripting (XSS) vulnerabilities in Webmin before 1.690 and Usermin before 1.600 allow remote attackers to inject arbitrary web script or HTML via vectors related to popup windows.
Cross-site scripting (XSS) vulnerability in view.cgi in Webmin before 1.680 allows remote attackers to inject arbitrary web script or HTML via the search parameter.
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.
