Symantec Security Expressions Cross-site Scripting and HTML Injection
October 6, 2009
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.
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 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
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.
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
* 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.
