Symantec Security Expressions Cross-site Scripting and HTML Injection 

October 6, 2009


Revision History


Remote Access 			Yes (Internal network only)
Local Access 			no
Authentication Required 	no
Exploit publicly available 	no

Symantecs SecurityExpressions Audit and Compliance Server is susceptible to a 
cross-site scripting and HTML injection vulnerability.

Affected Product(s)
Product 			Version 	Solution(s)

SecurityExpressions Audit and	4.1		4.1.1 KB49452 Hotfix 1
Compliance Server		4.1.1
Note: Customers running versions of Symantec SecurityExpressions Audit and 
Compliance Server prior to 4.1 should upgrade to the latest release and apply 
all available updates.

Symantec was notified of a cross-site scripting issue present in the Security 
Expression Audit and Compliance Server. The console fails to properly filter/ 
validate external client input from users with authorized access to the 
console. Error messages may be susceptible to unauthorized manipulation to 
generate potentially malicious scripts being directed to unsuspecting users.

Additionally, some response error messages are not properly encoded which could 
allow the potential for malicious HTML content to be injected into the returned 
response to a user. These issues could result in unauthorized access to other 
users sessions or to other systems on the internal network as well as 
unauthorized information disclosure.

Symantec Response
Symantec product engineers have released a hot fix for these issues in affected 
product versions. Symantec recommends all customers apply the latest available 
update to protect against threats of this nature.

Symantec is not aware of any exploitation of or adverse customer impact from 
these issues.

Symantec recommends that all customers apply Hotfix 1 as described in Symantec 
KB Article 49452 to protect against potential attempts to exploit these issues. 
Symantec KB Article 49452 with Hotfix 1 for affected products is available from 
the following location: https://kb.altiris.com/

If customers are unable to move to the latest release of Symantec 
SecurityExpressions Audit and Compliance Server or apply HotFix1 at this time, 
Symantec recommends ensuring console access is restricted to privileged users 
only 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 
    * Disable remote access or restrict it 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 Nate Roberts with Wipfli, LLP for reporting these 
issues and coordinating with us while Symantec resolved them.
