Type of vulnerability: Cross-Site Scripting (XSS) - Reflected

Exploit Vectors: Local and Remote

Vulnerability Description: The Web application management interface of Server Monitor contains multiple injection points, which allow for execution of Cross-site Scripting (XSS) attacks. Arbitrary client side code such as JavaScript can be included into certain parameters throughout the Web application. The following parameters and Web pages have been tested and verified; however, it is likely more views and parameters within the application are vulnerable:

event-history.asp (siteid, type) parameter
admin-history.asp (siteid, type) parameters
dashboard-view.asp (siteid, id) parameters
device-events.asp (siteid, dn) parameters
device-finder.asp (siteid, submit) parameters
device-list.asp (siteid, action, sel) parameters
device-monitors.asp (siteid, dn) parameters
device-views.asp (siteid, type) parameters
logbook.asp (siteid) parameter
monitor-events.asp (siteid) parameter
monitor-list.asp (siteid, action, sel) parameters
monitor-views.asp (siteid, type) parameters
reports-config-by-device.asp (siteid) parameter
reports-config-by-monitor.asp (siteid) parameter
reports-list.asp (siteid, sel) parameters
reports-monitoring-queue.asp (siteid) parameter
site-list.asp (action) parameter

Tested on: Windows XP, SP3, with Tembria Server Monitor v6.0.4 - Build 2229 default installation.

Affected software versions: Tembria Server Monitor v6.0.4 - Build 2229 (previous versions may also be vulnerable)

Impact: Successful attacks could disclose sensitive information about the user, session, and application to the attacker, resulting in a loss of confidentiality. Using XSS, an attacker could insert malicious code into a web page and entice naïve users to execute the malicious code.

Fixed in: Tembria Server Monitor v6.0.5 - Build 2252

Remediation guidelines: The vendor has created a fix for the vulnerabilities identified. Please update to version 6.0.5 - Build 2252 or newer.
