Detailsinfo

A vulnerability was found in Freedesktop spice-gtk (version unknown) and classified as critical. This issue affects an unknown function. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

libgio, when used in setuid or other privileged programs in spice-gtk and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: it could be argued that this is a vulnerability in the applications that do not cleanse environment variables, not in libgio itself.

The weakness was released 09/18/2012 by Tomas Hoger (Website). The advisory is shared at permalink.gmane.org. The identification of this vulnerability is CVE-2012-4425 since 08/21/2012. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

A public exploit has been developed by Sebastian Krahmer and been published before and not just after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 63 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 68628 (Oracle Linux 6 : spice-gtk (ELSA-2012-1284)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120647 (CentOS Security Update for spice-gtk (CESA-2012:1284)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Exploit-DB (21323), Tenable (68628), SecurityFocus (BID 55555†), OSVDB (85480†) and Vulnerability Center (SBV-36191†). Entry connected to this vulnerability is available at VDB-62318. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
