Detailsinfo

A vulnerability was found in OpenStack Nova (Cloud Software). It has been rated as problematic. This issue affects an unknown function. The manipulation with an unknown input leads to a information disclosure vulnerability (Key). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. The summary by CVE is:

OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2_SECRET_KEY. An attacker could also presumably brute force values for EC2_ACCESS_KEY.

The bug was discovered 10/05/2011. The weakness was released 11/26/2019. The identification of this vulnerability is CVE-2011-4076 since 10/18/2011. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 31 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 56722 (Fedora 16 : openstack-nova-2011.3-6.fc16 (2011-15449)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l.

Upgrading to version 2012.1 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (56722), SecurityFocus (BID 50359†) and OSVDB (76640†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
