Pligg CMS multiple XSS vulnerabilities

Multiple vulnerabilities have been discovered in Pligg CMS, which can be exploited by malicious people to conduct cross-site scripting attacks, according to Secunia.

1. Input passed to the “date” parameter in search.php (when “advancedsearch” is set to any value) 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.

This vulnerability is confirmed in version 1.1.4. Other versions may also be affected.

2. Input passed to the “return” parameter in login.php, “q” and “search” parameters in search.php, and “page” parameter in index.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.

3. Input passed to the “keyword” parameter in user.php (when “view” is set to “search”) 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.

These vulnerabilities are confirmed in version 1.1.5. Prior versions may also be affected.

Solution: Update to version 1.2.0.
