Cross site scripting
Description:
|
Symantec Management Console fails to properly validate/sanitize certain external input, allowing the potential for reflected cross-site scripting attempts. These attempts may come from authorized, but non-privileged network users or, in some instances, from unauthorized external individuals who are able to entice an actively logged-in management console user to click on a maliciously-crafted HTML link. Successful targeting of these issues could result in an authorized Symantec Management Console user's management session with associated privileges being hijacked.
Cross-site scripting is a trust exploitation that requires enticing a previously authenticated user to click on a malicious HTML link. An external attacker would need to successfully entice an authorized, privileged Symantec Management Console user to visit a malicious web site or click on a malicious HTML link in an email in any attempt to take advantage of this issue. In a normal installation, the Symantec Management console should not be accessible external to the network environment.

Information disclosure
Description:
|
The Symantec Management Console has an issue whereby XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts.
XML external entity (XXE) attacks may allow disclosure of local files, which may contain sensitive data such as passwords or private user data. The attack uses file URI schemes or relative paths in the system identifier to access files that should not normally be accessible. Since the attack occurs relative to the application processing the XML document, an attacker may use this trusted application to pivot to other internal systems, possibly disclosing other internal content via HTTP(S) requests or launching a CSRF attack to any unprotected internal services.
This issue was validated by the product team engineers. A Symantec Management Console set of updates, version ITMS 8.1 RU1 as well as patches ITMS 8.0_POST_HF6 & ITMS 7.6_POST_HF7, have been released which address the aforementioned vulnerabilities. Note that the Symantec Management Console's latest release and patches are available to customers through normal support channels. At this time, Symantec is not aware of any exploitations or adverse customer impact from these issues.
