Symantecs Message Filter management interface, the Brightmail Control Center,
is susceptible to a number of security concerns resulting from improper input
validation and authentication. Successful exploitation of these issues could
result in unauthorized privileged access to the application, execution of
unauthorized scripts in the context of the targeted users browser or disclosure
of application versioning information that could potentially be leveraged in
further exploitation attempts.
Product Version Solution
Symantec Message Filter 6.3 Upgrade to the latest release and apply
smf_630_p231 patch or migrate to
Symantec Messaging Gateway
NOTE: Symantec Message Filter is End-of-Support Life for Enterprise and SMB
customers with this update release. Symantec strongly recommends Enterprise
and SMB customers still using this legacy product migrate to the latest release
of Symantec Messaging Gateway for continued support and enhanced security
Symantec was notified of multiple security issues impacting the management
interface of the Symantec Message Filter application. The application does not
properly control access to the listening port or effectively filter external
input passed to the management interface. This could allow unauthorized access
to versioning information of various components installed with the application.
This type of information disclosure/reconnaissance could potentially be
leveraged in further exploit attempts to exploit the targeted application.
As a result of inadequate session management, an unauthorized network user or
an attacker who is able to leverage access to the network could potential
hijack the session of an authorized users, normally the Symantec Message Filter
administrator, session by capturing and reusing the users authorized session
identifier. If successful, an authorized users session could allow the
attacker to modify or disable the application.
The Symantec Message Filter management interface is also susceptible to
cross-site scripting and cross-site request forgery attempts. Both cross-site
scripting and cross-site request forgery are trust issues requiring the
attacker to entice an authenticated application user to click on a malicious
link either in a malicious URL or HTML email. A successful exploitation of the
cross-site scripting, depending on the nature of the link, could potentially
context of the browser of the targeted user. Successful exploitation of the
cross-site request forgery could potentially allow the attacker to execute
arbitrary commands on the application such as creating an unauthorized backdoor
access by creating an unauthorized admin account for the application.
In a normal installation, the Symantec Message Filter management console would
not be accessible external to the network. However, an authorized but
unprivileged network user who is able to access the application on the network
could attempt to exploit these weaknesses. An external attacker able to
leverage network access or entice an authorized user to click on a malicious
URL could potentially be successful in exploiting some of these issues.
Symantec engineers verified these issues and have released an update to address
them. Symantec engineers reviewed related functionality to further enhance the
overall security of Symantec Message Filter. Symantec has released Symantec
Message Filter 6.3 smf_630_p231 patch, http://www.symantec.com/docs/TECH191487,
currently available to customers.
Symantec strongly encourages customers still using the Brightmail Control
Center interface to Symantec Message Filter to apply the update as soon as
possible to prevent attempts of this nature. Symantec Message Filter is
End-of-Support Life for Enterprise and SMB customers with this update release.
Symantec highly recommends Enterprise and SMB customers migrate to Symantecs
Symantec is not aware of any exploitation of, or adverse customer impact from
As part of normal best practices, Symantec strongly recommends:
* Restrict access to administration or management systems to privileged users.
* Disable remote access or restrict it to trusted/authorized systems only.
* 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
