--
Impact:
Arbitrary code execution, information disclosure and possible cross site scripting.

--
Detailed Information:
Multiple vulnerabilities exist in Apple Quick Time Streaming Server and Apple Darwin Streamin Server, such that an attacker can gain information on the file system as an intelligence gathering activity for an attack on vulnerable services.

It is also possible for an attacker to inject malicious code into the log file for the server, the impact of this would be to execute the code when viewed by the administrator.

It is also directly vulnerable to cross site scripting issues.

--
Affected Systems:
Apple Darwin Streaming Server 4.1.2
Apple Quicktime Streaming Server 4.1.1

--
Attack Scenarios:
In the case of injecting code to the log files, the attacker would need to make requests to the streaming server with the code inserted in the request.

The attacker can execute an attack on the file system contents using a browser, the attacker needs to include a NULL byte in the request to reveal the directory structure.

The cross site scripting issue does not need anything specific to be done.
