Overview
Symantec Brightmail Gateways Control Center is susceptible to cross-site
scripting and elevation of privilege vulnerabilities.
Affected Product(s)
Product Version Solution(s)
Symantec Brightmail Gateway All prior to 8.0.1 Upgrade to 8.0.1
or later
Details
Symantec was notified of cross-site scripting and elevation of privilege issues
present in the Brightmail Control Center, the web-based management console of
Symantecs Brightmail Gateway Appliance. The Control Center fails to properly
filter external client input from users authorized access to the console.
Scripts used for administrative functions may be susceptible to malicious
manipulation potentially allowing access to other users sessions, unauthorized
access to other systems on the internal network or unauthorized information
disclosure.
In addition, some console functions could potentially be leveraged by an
authorized but non-privileged Control Center user to gain unauthorized elevated
access on the Symantec Brightmail Gateway.
Symantec Response
Symantec product engineers have released an update for these issues in all
affected product versions. Symantec is not aware of any attempts to exploit
these issues. However, we recommend that all customers upgrade to
non-vulnerable versions to protect against potential attempts to exploit.
How to Obtain the Update
The upgrade is available through the Software Update function of Symantec
Brightmail Gateway. It can also be downloaded from Symantec File Connect,
(https://fileconnect.symantec.com/LangSelection.jsp).
Mitigation
System administrators control access to the Symantec Brightmail Control Center
functionality through role-based administration. Symantec Brightmail
administrators normally have the rights that could potentially be gained
through exploiting these issues. However, in some environments users can be
authorized limited access to Control Center functionality, e.g., a user may be
allowed limited access to the Control Center to manage their personal
quarantine messages. This could result in an increased internal threat through
attempted exploitation of these issues by an authorized but non-privileged
user.
If customers are unable to upgrade to the fixed version of Symantec Brightmail
Gateway at this time, Symantec recommends ensuring Brightmail Control Center
access is restricted to privileged users until the upgrade can be applied.
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 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
