Description:
Three vulnerabilities has been reported in Symantec Scan Engine, which can be exploited by malicious people to disclose potentially sensitive information, bypass authentication and conduct man-in-the-middle (MITM) attacks.
1) A design error in the authentication mechanism used by Symantec Scan Engine can be exploited to gain access to the web-based administrative interface via specially-crafted XML requests sent to the server using its proprietary protocol.
2) Symantec Scan Engine uses a static private DSA key for SSL communications between the server and the administrative control application. This key cannot be changed and can potentially be exploited in a man-in-the-middle attack to decrypt all communications between the Scan Engine and an administrative client.
3) Symantec Scan Engine does not properly restrict access to files within the installation directory. This can be exploited by unauthenticated users to download any file located under the directory, such as the configuration file, the scanning logs, and the current virus definitions via HTTP requests.
The vulnerabilities have been reported in version 5.0.
Solution:
Update to version 5.1.
