A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than expected.

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7926-1 advisory.

    Kay discovered that OpenStack Keystone incorrectly handled the ec2tokens and s3tokens APIs. A remote     attacker could possibly use this issue to obtain unauthorized access and escalate privileges.
    (CVE-2025-65073)

    It was discovered that OpenStack Keystone had a time lag before a token should be revoked by the security     policy. A remote administrator could use this issue to maintain access for longer than expected.
    (CVE-2022-2447)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
