Symantec NetBackup OpsCenter is an optional web based application that, if 
installed, is installed separately in a customers environment for advanced 
monitoring, alerting, and reporting capabilities. Symantec NetBackup OpsCenter
for Linux/Unix is susceptible to Javascript injection that could potentially 
result in privileged access to the application.

Affected Products

Product                       Version          Solution(s)
Symantec NetBackup OpsCenter through  Upgrade to Symantec NetBackup 
for Linux/Unix                7.6.1            OpsCenter or apply 
                                               the mitigation identified below

Products Not Affected

Product                                        Version
Symantec NetBackup OpsCenter for Linux/Unix and prior
Symantec NetBackup OpsCenter for Windows       All


Symantec was notified of a javascript injection in the optional Symantec 
NetBackup OpsCenter advanced monitoring, alerting, and reporting application.
The application fails to properly filter/sanitize incoming javascript input, 
which could potentially allow injection and execution of specifically 
formatted content. Successful exploitation could potentially result in data 
loss or corruption, denial of service or complete compromise of the OpsCenter

In a normal installation, the Symantec NetBackup OpsCenter should not be 
externally accessible external to the network environment. Any attempt to 
exploit this issue would require network access either by an authorized 
network user or an external attacker able to leverage network access.

Symantec Response 

Symantec engineers verified this issue and have resolved it in Symantec 
NetBackup OpsCenter Customers should upgrade to this release to avoid 
potential incidents of this nature.

Symantec is not aware of exploitation of or adverse customer impact from these

Update Information

NetBackup OpsCenter is available through the following link for 
download and README information: 


Symantec recommends customers upgrade to the latest Symantec NetBackup 
OpsCenter release if installed in their environment. However, if 
unable to upgrade immediately, there is a workaround available to mitigate 
this issue in the affected versions of NetBackup OpsCenter per instructions in
TechAlert TECH227777, http://symantec.com/docs/TECH227777 .

Best Practices As part of normal best practices, Symantec strongly recommends
that customers:

- - Restrict access of 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 exploit by 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
