Sid:
2051

--
Summary:
designated root directory of a web server.

--
Impact:

unauthorized party.

--

be performaed against the server.

--
Attack Scenarios:
The attacker merely needs to enter a URL using ../ to traverse the file 
system for example:
http://www.foo.com/cgi-bin/cached_feed.cgi?../../../etc/passwd

--
Ease of Attack:
Simple

--
False Positives:
None Known

--
False Negatives:
None Known

--
Corrective Action:
Upgrade to version 2.0 or later
