Official description
RVTools, Version 3.9.2 and above, contain a sensitive data exposure vulnerability in the password encryption utility (RVToolsPasswordEncryption.exe) and main application (RVTools.exe). A remote unauthenticated attacker with access to stored encrypted passwords from a users' system could potentially exploit this vulnerability, leading to the disclosure of encrypted passwords in clear text. This vulnerability is caused by an incomplete fix for CVE-2020-27688.

The underlying weakness: 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.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
