The remote host is vulnerable to multiple attack vectors.
The remote host is running the Apple Quicktime Streaming Server. This version is vulnerable to a remote directory traversal flaw. An attacker exploiting this flaw would be able to access data outside of the web root. In addition, several remote denial of service (DoS) flaws have been reported in this version of QTSS. Thirdly, this version of QTSS has been reported prone to script disclosure attacks. An attacker exploiting this flaw would be able to read script source code. This could lead to more sophisticated attacks.
Upgrade to Apple Quicktime Server 4.1.4 or higher.
