CVE-2012-6494 - Nexpose Security Console - Session Hijacking
Product: Nexpose Security Console
Version: < 5.5.3
Tested Version: 5.5.1
Vendor Notified Date: December 19, 2012
Release Date: January 2, 2013
Authentication: Access to logs required.
Due to a flaw in the way the Nexpose Security Console logs session data,
it is possible to capture the session of a logged in user.
This could be especially interesting when using a central logging system
and system admin have access to logs but not the security console.
In capturing a user’s session as shown in the proof-of-concept below, an
attacker can gain access to the already logged in account. Once the
attacker has this information, they can then hijack the established
session and impersonate the owner in a variety of contexts.
Exploit steps for proof-of-concept:
1. Nexpose admin logs in.
2. While monitoring auth.log, the “Registered session” value is captured.
3. A request to the security console is made and intercepted using a proxy.
4. ‘JSESSIONID=<session>’ is replaced by
Vendor Notified: Yes
Vendor Response: Quickly escalated and resolved.
Vendor Update: Remediated in 5.5.4.
