US-CERT Vulnerability Note VU#118388
Symantec Scan Engine fails to properly perform authentication


	Symantec Scan Engine administrative web interface fails to
	properly authenticate users, which may allow a remote attacker
	to gain administrative access to the software.

I. Description

	The Symantec Scan Engine provides a programming interface to
	Symantec content scanning and virus detection services. The
	Symantec Scan Engine includes an administrative interface that
	is enabled and listening on port 8004/tcp by default.

	The web interface to Symantec Scan Engine uses a client-side
	Java applet to perform authentication. No authentication is
	performed on the server side.

II. Impact

	A remote, unauthenticated attacker may be able to gain access
	to the Symantec Scan Engine software. At the time of publication
	of this document, exploit code to remotely change the administrator
	password is available.

III. Solution

	Apply an update

	Apply an update to Symantec Scan Engine, as specified
	in the Symantec document SYM06-008.

	Restrict access

	You may wish to block access to the vulnerable software from
	outside your network perimeter, specifically by blocking access
	to the administrative port (8004/tcp by default). This will
	limit your exposure to attacks. However, blocking at the network
	perimeter would still allow attackers within the perimeter of
	your network to exploit the vulnerability. The use of host-based
	firewalls in addition to network-based firewalls can help
	restrict access to specific hosts within the network. It is
	important to understand your network's configuration and service
	requirements before deciding what changes are appropriate.
