Subject: XSS phpLDAPadmin: 1.2.0.5 (Debian package) and 1.2.2 (sourceforge)

Attach some PoC analysis related to a XSS vulnerability to phpldapadmin. I previously coordinate with the Cert-US in order they contact with Sourceforge and Debian, but receive they was unable to put in contact with them.

The first discover was on January 10 for 1.1.6 version, where after noticed that the same vulnerability was discover previously. For that reason I tested later for version 1.2.2 (sourceforge) and 1.2.0.5 (Debian package).
More reference: see the files attached

On January 24 I contacted to sourceforge and appear they fix the package but still persistence on debian packages.

Fix from sourceforge:
https://sourceforge.net/tracker/index.php?func=detail&aid=3477910&group_id=61828&atid=498546

Background:
===========
phpLDAPadmin is a web-based LDAP client. It provides easy, anywhere-accessible, multilanguage administration for your LDAP server. Its hierarchical tree-viewer and advanced search functionality make it intuitive to browse and administer your LDAP directory. Since it is a web application, this LDAP browser works on many platforms, making your LDAP server easily manageable from any location.
