CVE Reference(s):

Description


nigh7f411 has reported some vulnerabilities in ModernBill, which can be exploited by malicious people to conduct cross-site scripting attacks and compromise a vulnerable system.

1) Input passed to the "DIR" parameter in include/scripts/export_batch.inc.php, include/scripts/run_auto_suspend.cron.php, include/scripts/send_email_cache.php, include/misc/mod_2checkout/2checkout_return.inc.php, and include/html/nettools.popup.php is not properly verified before being used. This can be exploited to include arbitrary files from local or remote resources.

2) Input passed to the "new_language" 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.

The vulnerabilities are reported in versions 4.4.x. Other versions may also be affected.


Solution:
Update to version 4.4.2, which fixes the vulnerabilities in #1. Edit the source code to ensure that input is properly sanitised
