CVE-2015-7944

Status Candidate

Overview

The RESTful control interface (aka RAPI or ganeti-rapi) in Ganeti before 2.9.7, 2.10.x before 2.10.8, 2.11.x before 2.11.8, 2.12.x before 2.12.6, 2.13.x before 2.13.3, 2.14.x before 2.14.2, and 2.15.x before 2.15.2, when used in SSL mode, allows remote attackers to cause a denial of service (resource consumption) via SSL parameter renegotiation.

Ganeti Leaked Secret / Denial Of Service
Posted Dec 31, 2015
Authored by Open Source CERT, Daniele Bianco

Ganeti, an open source virtualization manager, suffers from multiple issues in its RESTful control interface (RAPI). The distributed replicated storage (DRBD) secret is leaked by the RAPI interface when job results are requested. Leveraging on the knowledge of this secret, a malicious user who had already gained access to the storage network of the cluster can retrieve instance data more easily and reliably. The RAPI interface is also vulnerable to a denial of service condition, triggered via SSL parameter renegotiation issued by a malicious client. The condition leads to resource exhaustion on the master node. Many versions are affected.
