Symantec Encryption Management Server Web Email Protection XSS
Details
Symantec was notified of an XSS issue existing in the Symantec Encryption Management Server web management interface. The issue is in the Web Email Protection component. Web Email Protection does not properly sanitize user-submitted HTML, which could allow arbitrary script to run in the context of the management console. A malicious individual would require either an authenticated Web Email Protection account, or be able to entice an authenticated Web Email Protection user to submit a specifically-configured encrypted email attachment. Interaction with the attached code during decryption and viewing could trigger the arbitrary code. Successful exploitation could potentially result in disclosure of or unauthorized access to, sensitive information on the server.
