Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions OpenStack Compute (Nova) versions 2012.1 through 2012.2

Description The issue allows remote authenticated users to cause a denial of service, resulting in excessive database lookup calls and server hang. This occurs when the DifferentHostFilter or SameHostFilter is enabled and a request contains many repeated IDs in the os:scheduler hints section.

Recommendations For OpenStack Compute (Nova) versions 2012.1 and 2012.2, consider disabling the DifferentHostFilter or SameHostFilter as a temporary workaround to minimize the risk of exploitation. Restrict access to the os:scheduler hints section to prevent requests with repeated IDs. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
