Summary
Rundeck's Key Storage converter plugin mechanism's encryption layer not working in 4.2.0, 4.2.1, 4.3.0
Details

Impact

The Key Storage converter plugin mechanism was not enabled correctly in Rundeck 4.2.0 and 4.2.1, resulting in use of the encryption layer for Key Storage possibly not working. Any credentials created or overwritten using Rundeck 4.2.0 or 4.2.1 might result in them being written in plaintext to the backend storage.

If you are using a "Storage Converter" plugin, such as jasypt-encryption configured via the rundeck.storage.converter.1.type=jasypt-encryption setting, and you installed 4.2.0 or 4.2.1 then please upgrade to one of the patched versions.

If you do not use a "Storage Converter" plugin, this would not affect you.

Patches

Rundeck 4.3.2 and 4.2.3 have fixed the code and upon upgrade will re-encrypt any plain text values. The fix is also included in 4.4.0 and later releases.

Note: 4.3.0 does not have the vulnerability, but does not include the patch to re-encrypt plain text values if 4.2.0 or 4.2.1 were used. The previously release 4.3.1 and 4.2.2 versions missed some re-encryption use cases that have been fixed in the versions mentioned above.

Workarounds

To prevent plaintext credentials from being stored in Rundeck 4.2.0/4.2.1, write access to key storage can be disabled via ACLs. After upgrading to 4.3.1 or later, write access can be restored.

This aclpolicy document can be used to deny all write access to storage:

---
by:
  group: '.*'
context:
  application: rundeck
for:
  storage:
  - deny:
    - create
    - update
description: deny create or update for storage in application context
---
by:
  group: '.*'
context:
  project: .*
for:
  storage:
  - deny:
    - create
    - update
description: deny create or update for storage in project context

To remove plaintext credentials, the metadata of stored keys can be used to detect if the key was stored with encryption enabled or not. In the case of the “jasypt-encryption” plugin, encrypted values will have a metadata field of “jasypt-encryption:encrypted”:”true” in the JSON metadata. If you are using the relational database as your key storage backend (rundeck.storage.provider.1.type=db), you can query for keys that are unencrypted. Here is an example query for Mysql:

select id,dir,name from storage where json_data not like "%jasypt-encryption:encrypted\":\"true%" and namespace is null and dir like "keys%"
