SecurityTracker Alert ID:  1028836
SecurityTracker URL:  http://securitytracker.com/id/1028836
CVE Reference:   CVE-2013-1616, CVE-2013-1617, CVE-2013-4670, CVE-2013-4671, CVE-2013-4672, CVE-2013-4673   (Links to External Site)
Date:  Jul 26 2013
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 5.1.0 and prior
Description:   Several vulnerabilities were reported in Symantec Web Gateway. A remote user can execute arbitrary commands on the target system. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks. A remote authenticated user can inject SQL commands.

A remote user with access to the Symantec Web Gateway (SWG) console interface can execute commands with elevated privileges [CVE-2013-1616].

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2013-4670]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Symantec Web Gateway software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can conduct cross-site request forgery attacks to take actions on the target site acting as the target user [CVE-2013-4671].

A remote authenticated user can supply a specially crafted parameter value to execute SQL commands on the underlying database [CVE-2013-1617].

The sudoer file configuration allows a remote authenticated user with sudo authorization to run unauthorized commands [CVE-2013-4672].

A remote user with access to the SWG console can exploit a Radius authentication flaw to run arbitrary code on the target system [CVE-2013-4673].

Wolfgang Ettlinger and Stefan Viehbock from SEC Consult reported several vulnerabilities. Offensive Security reported the Radius vulnerability.

Impact:   A remote user can execute arbitrary code on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Symantec Web Gateway software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote authenticated user can execute SQL commands on the underlying database.

Solution:   The vendor has issued a fix (5.1.1).
