6.7 8.5 5.1 AV:A/AC:L/AU:S/C:C/I:P/A:P
The Management Console in Symantec NetBackup appliance is susceptible to a
directory traversal vulnerability. An unauthorized network user could
potentially access and download privileged files.
Symantec NetBackup Appliance 2.0.x All Upgrade to Symantec NetBackup
Appliance 2.5.x or later
Symantec was notified of a directory traversal vulnerability in Symantecs
NetBackup Appliance 2.0.x Management Console web interface. Successfully
exploitation could potentially allow an authorized but unprivileged network
user access to privileged files to include system files that could be
leveraged to potentially gain unauthorized network access.
In a normal installation the Symantec NetBackup appliance management interface
should not be externally accessible from the network environment. This
restriction reduces exposure to the issue from external sources. However, an
authorized but unprivileged network user or an external attacker able to
successfully leverage network access could attempt to exploit the issue.
Symantec Response Symantec engineers had previously indentified this issue
during our internal reviews. It has been addressed in Symantec NetBackup
appliance 2.5.x. Symantec strongly recommends customers migrate from NetBackup
appliance 2.0.x to NetBackup appliance 2.5.x or later.
Updates are available through normal customer support locations.
Best Practices As part of best practices, Symantec strongly recommends:
* Restrict access to administration or management systems to privileged users.
* Restrict remote access, if required, to trusted/authorized systems only.
* Run under the principle of least privilege where possible to limit the
impact of threats.
* Keep all operating systems and applications updated with the latest vendor
* Follow a multi-layered approach to security. Run both firewall and
anti-malware applications, at a minimum, to provide multiple points of
detection and protection to both inbound and outbound threats.
* Deploy network and host-based 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
