OpsCenter Server Reflected Cross-Site Scripting

Symantec NetBackup OpsCenter Server Reflected XSS - High

Symantec NetBackup OpsCenter is an optional web based application that,
if installed, is installed separately in a customer's environment for
advanced monitoring, alerting, and reporting capabilities. Symantec
NetBackup OpsCenter is susceptible to a reflected cross-site scripting
(XSS) in the web console that could result in unauthorized access to the
application with the privileges of the affected user's browser.

Affected Products

Product				Version		Solution(s)

Symantec NetBackup OpsCenter	7.7 and prior	Upgrade to Symantec NetBackup OpsCenter 7.7.1


Symantec was notified of a reflected XSS in the optional Symantec NetBackup
OpsCenter advanced monitoring, alerting, and reporting application
console. XSS issues are the result of insufficient validation/sanitation
of user input and server output. A successful exploitation of this issue
is possible should a properly authenticated administrative user click on
a maliciously-crafted link with a logged-in browser also being used to
manage the OpsCenter console.

Cross-site scripting is a trust exploitation requiring enticing a previously
authenticated user to click on a malicious URL. To be exposed to other
than another authorized network user, an external attacker would need to
successfully entice an authorized, privileged Symantec OpsCenter console
user to visit a malicious web site or click on a malicious HTML link in
an email in any attempts to take advantage of this issue.

In a normal installation, the Symantec NetBackup OpsCenter should not
be externally accessible from 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 gain unauthorized access to
a logged-in authorized user's browser.

Symantec Response

Symantec engineers verified this issue and have resolved it in Symantec
NetBackup OpsCenter 7.7.1. 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 issues.

Update Information

NetBackup OpsCenter 7.7.1 is available through the
following link for download and README information:

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

    Restrict access of administration or management systems to privileged

    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 patches.

    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 vulnerabilities

Symantec would like to thank Guy Dahan for reporting this issue and
coordinating with us as we resolved it.
