CVE Published:

Summary

The vulnerability arises from an incomplete fix addressing the underlying flaw related to insecure temporary directory handling when executing commands under a different user using Ansible's 'become' directive. The failure to adequately secure these directories creates a race condition, particularly on systems utilizing Access Control Lists (ACLs) and Filesystems in Userspace (FUSE). This oversight affects various versions of both Ansible Engine and Ansible Tower, leaving systems potentially exposed to unauthorized access and exploitation.

Affected Version(s)

ansible ansible-engine 2.7.18 and prior

ansible ansible-engine 2.8.12 and prior

ansible ansible-engine 2.9.9 and prior
