Security Advisories Relating to Symantec Products - Symantec Veritas NetBackup Administration JAVA GUI Elevation of Privilege


September 24, 2008

Revision History


Risk Impact


Remote Access (adjacent network)Yes
Local AccessNo
Authentication RequiredYes
Exploit availableNo


A non-privileged but authorized user could potentially leverage Symantec Veritas NetBackup JAVA Administration Graphical User Interface (GUI) to execute code with elevated privileges on the server.

Affected Products

Symantec Veritas NetBackup Enterprise Server and Symantec Veritas NetBackup Server5.1All5.1 MP7
6.0All6.0 MP7

Note: Product versions prior to those listed above are NOT supported. Customers running legacy product versions should upgrade and apply available updates.

Unaffected Products

The Java Administration GUI (jnbSA) in affected versions of Veritas NetBackup could potentially allow an authorized but non-privileged user to run commands which would normally require a higher privilege to execute. The malicious user would need to be authenticated on the system and logged in to the GUI in order to attempt to exploit this vulnerability.

Symantec Response

Symantec engineers have verified that the vulnerability exists in the versions of Veritas NetBackup listed in the table above. Updates have been released to resolve the issue.

Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue.

The updates for affected products are available from the "Related Documents" section of the following Technote:



A successful attacker must be logged in to the GUI to launch an attack. Access to the NetBackup server should be limited to trusted users.

Customers who want to limit exposure to any possibility of this type of attempt prior to upgrading can disable the JAVA GUI as follows:

move the bpjava* binaries out of ’/usr/openv/netbackup/bin’ (UNIX/Linux)


out of ‘\VERITAS\Netbackup\bin’ (Windows)

Best Practices

As part of normal best practices, Symantec strongly recommends:
  • Restrict access to administration or management systems to privileged users.
  • Restrict remote access, if it is required, to trusted/authorized systems only.
  • Run under the principle of least privilege where possible to limit the impact of potential exploits.
  • Keep all operating systems and applications updated with the latest vendor patches.
  • Follow a multi-layered approach to security. Run both firewall and antivirus applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
  • 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


Symantec would like to thank Kyle Noonan of Sun Microsystems for reporting this issue and coordinating with us on the resolution.
