rgod has reported some vulnerabilities in GuppY, which can be exploited by malicious people to disclose sensitive information and compromise a vulnerable system.
1) Input passed to the "_SERVER[REMOTE_ADDR]" parameter in "error.php" isn't properly sanitised before being stored in a PHP script. This can be exploited to inject and execute arbitrary PHP code.
Successful exploitation requires that "register_globals" and "magic_quotes_gpc" are disabled.
2) Input passed to the "meskin" parameter in "editorTypetool.php" and the "lng" parameter in "archbatch.php" and "nwlmail.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "register_globals" is enabled and that "magic_quotes_gpc" is disabled.
The vulnerabilities have been reported in version 4.5.9 and prior. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised and verified.
