Core Security Technologies has reported multiple vulnerabilities in ManageEngine ADSelfService Plus, which can be exploited by malicious people to conduct cross-site scripting attacks and bypass certain security restrictions.

1) An error in the password reset mechanism can be exploited to bypass the security questions and change an arbitrary user's password by visiting the accounts/ResetResult page directly.

This vulnerability is reported in version 4.4. Other versions may also be affected.

2) Input passed to the "searchString" parameter in EmployeeSearch.cc (when "actionId" is set to "showList" or "Search") 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.

3) Input passed to the "searchType" parameter in EmployeeSearch.cc 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.

The vulnerabilities #2 and #3 are confirmed in version 4.5. build 4530. Other versions may also be affected.

NOTE: Additionally, a weakness exists in the security question verification mechanism and can be exploited to reduce the number of required questions and disable the captcha verification, which may allow answering a question via a brute force attack.

Solution
Update to version 4.5 Build 4530 which reportedly fixes vulnerability #1. Filter malicious characters and character sequences using a proxy.
