Description:
Some vulnerabilities have been discovered in PHPNews, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed to the "url", "id", "subject", "username", and "time" parameters in templates/link_temp.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.
2) Input passed to the "url", "catid" and "category" parameters in templates/cat_temp.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.
Successful exploitation requires in both cases that "register_globals" is enabled.
The vulnerabilities are confirmed in version 1.3.0. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
Provided and/or discovered by:
1) Detefix
2) An anonymous person
