Session Authentication Bypass Vulnerability


August 14, 2008

-- Affected Vendors:


-- 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
