Description:
Two vulnerabilities have been reported in Usermin, where the most critical can be exploited by malicious people to compromise a vulnerable system.
1) An input validation error within the web mail functionality can be exploited to inject arbitrary shell commands, which will be executed when a user views a specially crafted HTML mail.
Successful exploitation allows execution of arbitrary commands with the privileges of the Usermin user.
This vulnerability has been reported in Usermin 1.070 and 1.080.
2) Malicious, local users can exploit an unspecified error within the installation routine by creating the "/tmp/.webmin" directory before the installation routine does so.
This vulnerability affects both Usermin and Webmin.
Solution:
Update to version Usermin 1.090.
http://www.webmin.com/index6.html
Update to version Webmin 1.160.
