Cross Site Scripting (XSS) in serendipity 1.3 installer, CVE-2008-1386



The installer of serendipity 1.3 has various Cross Site Scripting issues. This is considered low priority, as attack scenarios are very unlikely.

Various path fields are not escaped properly, thus filling them with javascript code will lead to XSS. MySQL error messages are not escaped, thus the database host field can also be filled with javascript.


If you are doing a fresh installation of serendipity, use version 1.3.1.

In general, don't leave uninstalled webapplications laying around on a public webspace.
