Risk Impact
High

Details
Symantec has provided product updates for all supported products affected by a remote access vulnerability allowing unauthorized remote access and the downloading of arbitrary files. This issue impacts the backup servers for VERITAS Backup Exec, media servers running the VERITAS NetWare Media Server Option, and the system running the remote agents indicated above. An encrypted but static password is transferred during the authentication process between the agent and the server that, when properly manipulated can be leveraged to gain remote access to the application and download arbitrary files from and to the backup server. A public exploit has been released to the metasploit framework.

Symantec Response
Symantec product engineers quickly validated this issue and delivered fixes and Technical Support documentation for the following supported product versions:

VERITAS Backup Exec for Windows Servers
http://support.veritas.com/docs/278434

VERITAS Backup Exec for NetWare Servers
http://support.veritas.com/docs/278431

VERITAS NetBackup for NetWare Media Server Option

Symantec recommends customers immediately apply the latest update for their supported product versions as soon as they are available to protect against these types of threats.

Customers running unsupported product versions are strongly advised to upgrade to the latest supported version and apply all updates. The risk for this issue can be substantially mitigated if port 10000 is not available outside of the perimeter network.

Symantec also recommends customers immediately apply updated security signatures

Mitigation Recommendations:
Symantec Response has created IPS/IDS signatures to detect and prevent attempts to exploit this issue.

Symantec ManHunt 3.0 signatures are available for update from the Symantec Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Product_MH.html

Symantec Network Security Appliance 7100 signatures are available for update from the Symantec Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Product_SNS.html

Symantec Gateway Security 2.0 signatures are available for update from the Symantec Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Product_SGS.html

Symantec Client Security 2.0 and 3.0 signatures are available for update via LiveUpdate and from the Security Response Update Center at:
http://www.symantec.com/avcenter/security/Content/Product/Product_SCS.html

Customers using Symantec Client Security 2.0 and 3.0 should have already uploaded this signature if they run LiveUpdate regularly. If not, Symantec recommends customers manually running Symantec LiveUpdate to ensure they are running the most current protection. Symantec recommends customers block external access to the service (TCP port 10000) at the network perimeter until they can effectively update their affected systems. If required, permit access for trusted or internal network resources only.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy network intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities.

As a part of normal best practices, users should keep vendor-supplied patches for all application software and operating systems up-to-date.
