TWiki Two Cross-Site Scripting Vulnerabilities

Description

Mesut Timur has discovered two vulnerabilities in TWiki, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed to the "newtopic" parameter in bin/view/Main/Jump (when "template" is set to "WebCreateNewTopic") 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.
2) Input passed via the URL to pages containing a slideshow presentation using the SlideShowPlugin is not properly sanitised in lib/TWiki/Plugins/SlideShowPlugin/SlideShow.pm 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.
The vulnerabilities are confirmed in version 5.0.2. Prior versions may also be affected.
