Overview
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 7.6.0.2 through Upgrade to Symantec NetBackup
for Linux/Unix 7.6.1 OpsCenter 7.6.1.1 or apply
the mitigation identified below
Products Not Affected
Product Version
Symantec NetBackup OpsCenter for Linux/Unix 7.6.0.1 and prior
Symantec NetBackup OpsCenter for Windows All
Details
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
application.
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 7.6.1.1. 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 7.6.1.1 is available through the following link for
download and README information:
http://www.symantec.com/business/support/index?page=productlanding&key=58596
Mitigations/Workaround
Symantec recommends customers upgrade to the latest Symantec NetBackup
OpsCenter 7.6.1.1 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
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
