Symantec VERITAS Storage Foundation Administration Service DoS Vulnerability



The VERITAS Storage Foundation is made up of the Veritas File System, Veritas Volume Replicator (VVR) products and some other utilities. It allows virtualization of storage over a variety of platforms, and contains a remote administration application to configure and monitor the elements of the storage network. More information can be found at the following URL.



Remote exploitation of an input validation vulnerability in VERITAS Software Corp.'s Storage Foundation 4.3 Enterprise Administration service could allow an unauthenticated attacker to consume excessive resources or crash the service.

The vulnerability specifically exists in the handling of packets delivered to the VVR Administration service port, TCP/8199. By sending specially crafted requests to a vulnerable host, attackers are able to control the size value for memory allocation. In cases where requests are made for more memory than the system is able to allocate, the service attempts to write to an invalid pointer, which crashes the service. If allocation succeeds, the resulting memory will not be released until the connection is closed. This allows a resource consumption denial of service attack.


Successful exploitation of this vulnerability allows remote attackers to cause the affected service to terminate. As no checks are made that the values given make sense, it is possible to cause the service to allocate large amounts of memory, potentially causing severely degraded system performance and instability in other processes.

Crashing the administration service, which is restarted after 60 seconds, would most likely not directly impact the operation of the replication service itself. However, it likely the resource consumption variation would prevent the affected system from being usable for the duration of the attack.


iDefense Labs confirmed that VERITAS Storage Foundation for Windows version 4.3.01 is vulnerable. It is suspected that all previous versions are vulnerable.


Applying traffic filtering to the affected port, allowing only hosts that an administrator uses, will help mitigate exposure to the vulnerability.
