ZDI-08-053: Symantec Veritas Storage Foundation Scheduler Service NULL 
Session Authentication Bypass Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-053
August 14, 2008

-- Affected Vendors:
Symantec

-- Affected Products:
Symantec Veritas Storage Foundation

-- Vulnerability Details:
This vulnerability allows an attacker to execute arbitrary code on
vulnerable installations of Symantec Veritas Storage Foundation. User
interaction is not required to exploit this vulnerability.
Authentication is not required to exploit this vulnerability.

The specific flaw exists in the functionality exposed by the Storage
Foundation for Windows Scheduler Service, VxSchedService.exe, which
listens by default on TCP port 4888. The management console allows NULL
NTLMSSP authentication thereby enabling a remote attacker to add,
modify, or delete snapshots schedules and consequently run arbitrary
code under the context of the SYSTEM user. 

-- Vendor Response:
Symantec has issued an update to correct this vulnerability. More
details can be found at:
