Webmin before 1.290 and Usermin before 1.220 calls the simplify_path function before decoding HTML, which allows remote attackers to read arbitrary files, as demonstrated using "..%01" sequences, which bypass the removal of "../" sequences before bytes such as "%01" are removed from the filename. NOTE: This is a different issue than CVE-2006-3274.

Directory traversal vulnerability in Webmin before 1.280, when run on Windows, allows remote attackers to read arbitrary files via \ (backslash) characters in the URL to certain directories under the web root, such as the image directory.
