Sid:
1569

--
Summary:
This event is generated when an attempt is made to execute a directory
traversal attack.

--
Impact:
Information disclosure. This is a directory traversal attempt which can
lead to information disclosure and possible exposure of sensitive
system information.

--
Detailed Information:
Directory traversal attacks usually target web, web applications and ftp
servers that do not correctly check the path to a file when requested by
the client.

This can lead to the disclosure of sensitive system information which may
be used by an attacker to further compromise the system.

--
Affected Systems:

	AHG EZshopper v3.0 and v2.0 for UNIX

--
Attack Scenarios:
An authorized user or anonymous user can use the directory traversal 
technique, to browse folders outside the ftp root directory. Information
gathered may be used in further attacks against the host.

--
Ease of Attack:
Simple. No exploit software required.

--
False Positives:
None known

--
False Negatives:
None known

--
Corrective Action:
Apply the appropriate vendor supplied patches

Upgrade the software to the latest non-affected version.
