-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Title: Symantec Scan Engine Multiple Vulnerabilities Threat: Moderate Impact: Unauthorized access Product: Symantec Scan Engine Situation Overview: Three vulnerabilities have been discovered in the Symantec Scan Engine. Symantec Scan Engine is a TCP/IP server and programming interface that enables third parties to incorporate support for Symantec content scanning technologies into their proprietary applications. This gateway-level product should not be confused with Symantec's desktop product. The Symantec Scan Engine fails to properly authenticate web-based user logins. Anyone with knowledge of the underlying communication mechanism can control the Scan Engine server. Symantec Scan Engine uses a static private DSA key for SSL communications. This key cannot be changed by end users and is easily extracted. This opens the product to a potential man-in-the-middle attack. There is a vulnerability in Symantec Scan Engine that allows unauthenticated remote users to download any file located under the Symantec Scan Engine installation directory. For instance, the configuration file, the scanning logs, and the current virus definitions can all be accessed by any remote user using regular or specially crafted HTTP requests.
