Description:
Ivan Fratric has reported two vulnerabilities in WordPress, which can be exploited by malicious people to compromise vulnerable systems.
1) Input passed to the "ix" parameter in wp-includes/feed.php is not properly sanitised before being used in "eval()" calls. This can be exploited to execute arbitrary PHP code.
2) Input passed to the "iz" parameter in wp-includes/theme.php is not properly sanitised before being used to execute commands. This can be exploited to execute arbitrary shell commands.
NOTE: The vulnerabilities were reportedly added by someone breaking into WordPress's servers.
The vulnerabilities are reported in version 2.1.1 downloaded on 2007-02-25 or later.
Solution:
Update to version 2.1.2.
