commit 8f999d1c1f54a903c1da648ecaa2ce44acdb1fd1 Author: Dave Wilde (d34dh0r53) <[email protected]> Date: Thu Oct 13 15:37:53 2022 -0500 Limit token expiration to application credential expiration If a token is issued with an application credential we need to check the expiration of the application credential to ensure that the token does not outlive the application credential. This ensures that if the token expiration is greaten than that of the application credential it is reset to the expiration of the application credential and a warning is logged. Please see CVE-2022-2447 for more information.

Engineering Team, which is subscribed to OpenStack Identity (keystone). https://bugs.launchpad.net/bugs/1992183 Title: Openstack: Application credential token remains valid longer than expected (CVE-2022-2447) Status in OpenStack Identity (keystone): Fix Released Status in OpenStack Security Advisory: Incomplete Bug description: Description of problem: Keystone issues tokens with the default lifespan regardless of the lifespan of the application credentials used to issue them. If the configured lifespan of an identity token is set to be 1h, and the application credentials expire in 1 minute from now, a newly issued token will outlive the application credentials used to issue it by 59 minutes. How reproducible: 100% Steps to Reproduce: 1. Create application credentials with short expiration time (e.g. 10 seconds) 2. openstack token issue --> the returned token has standard expiration, for example 1 hour. The script below confirms that the token continue being valid after the application credentials expired. ```bash #!/usr/bin/env bash set -Eeuo pipefail openstack image create --disk-format=raw --container-format=bare --file <(echo 'I am a Glance image') testimage -f json > image.json image_url="$(openstack catalog show glance -f json | jq -r '.endpoints[] | select(.interface=="public").url')$(jq -r '.file' image.json)" openstack application credential create \ --expiration="$(date --utc --date '+10 second' +%Y-%m-%dT%H:%M:%S)" \ token_test \ -f json \ > appcreds.json cat <<EOF > clouds.yaml clouds: ${OS_CLOUD}: auth: auth_url: <auth_url> application_credential_id: '$(jq -r '.id' appcreds.json)' application_credential_secret: '$(jq -r '.secret' appcreds.json)' auth_type: "v3applicationcredential" identity_api_version: 3 interface: public region_name: <region_name> EOF # Override ~/.config/openstack/secure.yaml touch secure.yaml openstack token issue -f json > token.json echo "appcreds expiration: $(jq -r '.expires_at' appcreds.json)" for i in {1..10}; do sleep 100 echo -ne "$(date --utc --rfc-3339=seconds)\t" curl -isS -H "X-Auth-Token: $(jq -r '.id' token.json)" --url "$image_url" | head -n1 done ``` Actual results (on a cloud with tokens duration of 24h): appcreds expiration: 2022-07-08T13:55:02.000000 2022-07-08 13:56:38+00:00 HTTP/1.1 200 OK 2022-07-08 13:58:19+00:00 HTTP/1.1 200 OK 2022-07-08 14:00:00+00:00 HTTP/1.1 200 OK 2022-07-08 14:01:42+00:00 HTTP/1.1 200 OK 2022-07-08 14:03:23+00:00 HTTP/1.1 200 OK 2022-07-08 14:05:07+00:00 HTTP/1.1 200 OK 2022-07-08 14:06:49+00:00 HTTP/1.1 200 OK 2022-07-08 14:08:37+00:00 HTTP/1.1 200 OK 2022-07-08 14:10:18+00:00 HTTP/1.1 200 OK 2022-07-08 14:12:00+00:00 HTTP/1.1 200 OK Expected results: appcreds expiration: 2022-07-08T13:55:02.000000 2022-07-08 13:54:38+00:00 HTTP/1.1 200 OK 2022-07-08 13:58:19+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:00:00+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:01:42+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:03:23+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:05:07+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:06:49+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:08:37+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:10:18+00:00 HTTP/1.1 401 Unauthorized 2022-07-08 14:12:00+00:00 HTTP/1.1 401 Unauthorized To manage notifications about this bug go to: https://bugs.launchpad.net/keystone/+bug/1992183/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
