Hector Manuel Escalona Mendoza has discovered some vulnerabilities, a security issue, and a weakness in ManageEngine Applications Manager, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or conduct cross-site scripting attacks.
1) Input passed to "showlink" parameter in /jsp/DiscoveryProfiles.jsp, "attributeIDs", "attributeToSelect", "redirectto", and "resourceid" parameters in /jsp/ThresholdActionConfiguration.jsp, "page" and "redirect" parameters in jsp/UpdateGlobalSettings.jsp, and "haid" and "returnpath" parameters in showTile.do is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Missing authentication checks in certain pages (e.g. monitorType.do) can be exploited to disclose potentially sensitive information or modify certain application settings.
3) It is possible to e.g. view the "Home->Summary" information via a URL with an invalid target location (e.g. "http://[host]/-")
The vulnerabilities, security issue, and weakness are confirmed in version 8.1 (build 8100). Other versions may also be affected.
Solution: Reportedly, a fix is already available from the vendor and will also be included in the next service pack available approximately by the end of the month.
