MITIGATION

Details

Symantec Data Insight does not properly validate or sanitize external input to user accessible fields on some forms available for use on the management console.

Cross-site scripting and html injection vulnerabilities were reported in forms available through the Symantec Data Insight management console. Cross-site scripting and HTML injection are trust exploitations generally requiring a malicious non-authenticated attacker enticing an authenticated user to click on a malicious link or a malicious network user with authorized or unauthorized access to the vulnerable fields able to inject malicious arbitrary scripts. A successful exploitation, depending on the nature of the attack, could potentially result in arbitrary html scripts executed in the context of the targeted user or the application depending on the vulnerable field being targeted.

In a normal installation, the Symantec Data Insight management console should not be accessible external to the network. However, an authorized but unprivileged network user or an external attacker able to leverage network access could attempt to exploit these weaknesses.

Symantec Response
Symantec product engineers verified these issues and have released updates to resolve them. Customers should update to Symantec Data Insight 4.5.

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

Update Information

Symantec Data Insight 4.5 is available through Symantec File Connect.

Best Practices
As part of normal best practices, Symantec strongly recommends the following:

• Restrict access to administrative or management systems to authorized 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 potential exploit.
• Keep all operating systems and applications current with vendor patches.
• Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications 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 the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
