Sambar Server is a multi-threaded HTTP server for Microsoft Windows and Unix systems.
|
|
|
|
Sambar WWW Server is bundled with a sample script('pagecount') which creates temporary files on the host. However, it is possible for a remote attacker to craft a web request which will cause pagecount to overwrite existing files. Files attacked in this manner will be corrupted.
|
|
|
|
Loss of critical data and a denial of services may occur if system files are overwritten.
|
|
|
|
http://sambarserver/session/pagecount?page=index will create a file in Sambar temp directory with name 'index'
|
|
|
|
http://sambarserver/session/pagecount?page=../../../../../../autoexec.bat then the script will rewrite the first symbols of c:\autoexec.bat with it's number.

|
So we are able to add some text to any file on the disk. |
