nnposter has discovered some vulnerabilities in Alkacon OpenCms, which can be exploited by malicious users to disclose potentially sensitive information and malicious people to conduct cross-site scripting attacks.

1) Input passed to the "filePath" parameter in opencms/system/workplace/admin/workplace/logfileview/logfileViewSettings.jsp is not properly sanitised before being returned to an administrator. This can be exploited to execute arbitrary HTML and script code in an administrator's browser session in context of an affected site.

2) Input passed to the "filePath" parameter in opencms/system/workplace/admin/workplace/logfileview/logfileViewSettings.jsp is not properly verified before being used to display files, which can be exploited to disclose the content of arbitrary files.

Successful exploitation requires valid administrator credentials.

3) Input passed to the "searchfilter" parameter in opencms/system/workplace/admin/accounts/users_list.jsp and opencms/system/workplace/admin/workplace/sessions.jsp 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 are confirmed in version 7.0.4. Other versions may also be affected.
