Detailsinfo

A vulnerability was found in Red Hat Enterprise Virtualization Manager 3.3 (Virtualization Software). It has been declared as problematic. Affected by this vulnerability is some unknown processing of the component SPICE Client Invocation Handler. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, and integrity. The summary by CVE is:

The remote-viewer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.3, when using a native SPICE client invocation method, initially makes insecure connections to the SPICE server, which allows man-in-the-middle attackers to spoof the SPICE server.

The weakness was disclosed 01/21/2014 by Michael Samuel with Amcom as RHSA-2014:0038-1 as confirmed advisory (Website). It is possible to read the advisory at rhn.redhat.com. This vulnerability is known as CVE-2013-6434 since 11/04/2013. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK. The advisory points out:

A flaw was found in the way Red Hat Enterprise Virtualization Manager relayed SPICE connection information to remote-viewer when a native SPICE client invocation method was used. As a result, remote-viewer attempted an insecure connection first and only switched to a secure connection when requested by the SPICE server. An attacker able to intercept the SPICE connection could use this flaw to conduct man-in-the-middle attacks.

After immediately, there has been an exploit disclosed. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 78993 (RHEL 6 : Virtualization Manager (RHSA-2014:0038)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat Local Security Checks.

Upgrading eliminates this vulnerability. The upgrade is hosted for download at access.redhat.com. A possible mitigation has been published immediately after the disclosure of the vulnerability.
