[原文]VERITAS Backup Exec 9.0 through 10.0 for Windows Servers, and 9.0.4019 through 9.1.307 for Netware, allows remote attackers to cause a denial of service (Remote Agent crash) via (1) a crafted packet in NDMLSRVR.DLL or (2) a request packet with an invalid (non-0) "Error Status" value, which triggers a null dereference.


[CNNVD]Veritas Backup Exec 拒绝服务攻击漏洞(CNNVD-200506-212)

iDEFENSE Security Advisory 06.23.05-3 - Remote exploitation of a denial of service condition in Veritas Software Corp.'s Backup Exec allows attackers to crash the vulnerable service.

Veritas Backup Exec Remote Agent NDMLSRVR.DLL DoS Vulnerability

iDEFENSE Security Advisory 06.23.05
www.idefense.com/application/poi/display?id=270&type=vulnerabilities
June 23, 2005

I. BACKGROUND

VERITAS Backup Exec is an advanced backup and restore solution for 
Microsoft Windows server environments. More information is available 
from the vendor's website:

    http://veritas.com/Products/www?c=product&refId=57

II. DESCRIPTION

Remote exploitation of a denial of service condition in Veritas Software
Corp.'s Backup Exec allows attackers to crash the vulnerable service.

The Veritas Backup Exec Agent listens on TCP port 10000 and is
responsible for accepting connections from the backup server when a
backup is to occur. Typically the agent would be installed on most
servers and important workstations in an enterprise environment. Veritas
Backup Exec uses the standard NMDP protocol to communicate with the
listening agents.

The vulnerability specifically exists within NDMLSRVR.DLL due to a null
pointer dereference upon parsing of a maliciously crafted packet at the
following instruction:

    0x01053355 MOVZX EAX, WORD PTR [ESI]

An unhandled exception occurs resulting in a crash of the program and a
denial of service condition.

III. ANALYSIS

Exploitation does not require authentication, thereby allowing any 
remote attacker to cause the denial of service and disruption of backup 
capabilities.

IV. DETECTION

iDEFENSE has confirmed the existence of this vulnerability in Backup
Exec for Windows Servers version 10.0 and 10.0 SP1, the latest versions
available as of this report. It is suspected that older versions are
also vulnerable.

Several vendors ship or use Veritas software including Hitachi and NEC
Corporation.

V. WORKAROUND

Use a firewall to restrict incoming connections to trusted workstations 
running the Backup Exec client software which uses port 10000 TCP.

VI. VENDOR RESPONSE

The vendor has addressed this vulnerability in security advisory
VX05-001:

   http://seer.support.veritas.com/docs/276533.htm

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2005-0772 to this issue. This is a candidate for inclusion
in the CVE list (http://cve.mitre.org), which standardizes names for
security problems.
