CVE-2022-31044 is a vulnerability in Pagerduty Rundeck
Published on June 15, 2022
Plaintext Storage of Keys and Passwords in Rundeck and PagerDuty Process Automation
Rundeck is an open source automation service with a web console, command line tools and a WebAPI. 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. This affects those using any `Storage Converter` plugin. Rundeck 4.3.1 and 4.2.2 have fixed the code and upon upgrade will re-encrypt any plain text values. Version 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. 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.

Weakness Types
Unprotected Storage of Credentials
Storing a password in plaintext may result in a system compromise. Password management issues occur when a password is stored in plaintext in an application's properties or configuration file. Storing a plaintext password in a configuration file allows anyone who can read the file access to the password-protected resource.
Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
