Webmin, Usermin: File Disclosure Webmin and Usermin are vulnerable to an arbitrary file disclosure through a specially crafted URL. webmin/usermin 2006-08-06 2006-08-06 138552 remote 1.290 1.290 1.220 1.220

Webmin is a web-based interface for Unix-like systems. Usermin is a simplified version of Webmin designed for use by normal users rather than system administrators.

A vulnerability in both Webmin and Usermin has been discovered by Kenny Chen, wherein simplify_path is called before the HTML is decoded.

A non-authenticated user can read any file on the server using a specially crafted URL.

For a temporary workaround, IP Access Control can be setup on Webmin and Usermin.

All Webmin users should update to the latest stable version:

# emerge --sync # emerge --ask --verbose --oneshot ">=app-admin/webmin-1.290"

All Usermin users should update to the latest stable version:

# emerge --sync # emerge --ask --verbose --oneshot ">=app-admin/usermin-1.220" CVE-2006-3392 koon hlieberman
