Exploits a file disclosure vulnerability in Webmin (CVE-2006-3392)
|
|
|
|
Webmin before 1.290 and Usermin before 1.220 calls the simplify_path function before decoding HTML.
|
|
This allows arbitrary files to be read, without requiring authentication, using "..%01" sequences
|
|
to bypass the removal of "../" directory traversal sequences.
