Virtech Netquery allows attackers to run script via browser

CVE-2006-5661 · published 20 years ago
Summary

The nquser.php page in Virtech Netquery can be fooled into executing code that a hacker puts in the User-Agent field of a web request. When a victim visits the site, the malicious code runs in their browser, potentially exposing personal data or taking control of their session. Apply any available updates or patches from the vendor and consider filtering or blocking unusual User-Agent strings until the fix is in place.
