JeiAr has discovered multiple vulnerabilities in TikiWiki, allowing malicious people to conduct Cross Site Scripting, SQL injection, script insertion attacks and compromise a vulnerable system.

1) Path information can be disclosed by supplying invalid input or requesting certain scripts directly.

2) Input to multiple scripts isn't properly verified before it is returned to the user. This can be exploited to execute arbitrary HTML or script code in a user's browser session in context of an affected site by tricking the user into visiting a malicious website or follow a specially crafted link.

3) Input passed to multiple scripts isn't properly sanitised before it is used in SQL queries. This allows manipulation of SQL queries by injecting arbitrary SQL code.

4) Certain parameters in various functionality allow URLs and scripts to be inserted. These can contain references to administrative functions, which will be executed when an administrative user views a profile or page with malicious links.

5) An input validation error can be exploited to access directories outside the web root via the "../" directory traversal character sequence.

6) It is possible to upload arbitrary files to "/img/wiki_up/" folder. This can be exploited to place arbitrary code on the system.

This has been reported to affect version 1.8 and prior.

Solution
This has been fixed in TikiWiki 1.8.2 (Polaris) and 1.7.7 (eta carinae).
