Missing Release of Resource after Effective Lifetime vulnerability in Apache CloudStack's scoped global configuration functionality.

MEDIUM 6.8EPSS 0.59%

Does this matter?

Lower severity and a low EPSS score (0.59%). Track it; it rarely justifies an emergency change on its own.

Description

Missing Release of Resource after Effective Lifetime vulnerability in Apache CloudStack's scoped global configuration functionality. It affects different modules and plugins of the CloudStack management server, including Quota, Host-HA, etc., and may lead to eventual denial of service (DoS) scenario for the management server. This issue affects Apache CloudStack: from 4.7.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
