Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

RVTools versions 3.9.2 and above contain a sensitive data exposure vulnerability in the password encryption utility (RVToolsPasswordEncryption.exe) and main application (RVTools.exe). An attacker with access to stored encrypted passwords on a user's system can potentially decrypt them to clear text due to an incomplete fix for CVE-2020-27688.

MitigationImmediately apply any vendor patches for RVTools when available, rotate all credentials that were stored using the affected encryption utility, and review systems for unauthorized access given the exposure of stored passwords.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed RVTools version
    Locate the RVTools installation directory (typically C:\Program Files\RVTools or C:\Program Files (x86)\RVTools) and view the version properties of RVTools.exe, or run 'RVTools.exe -v' from the command line if supported
    Affected if The installed version is 3.9.2 or higher but below 4.5.0
  2. Verify presence of vulnerable executables
    Confirm that RVToolsPasswordEncryption.exe exists in the RVTools installation folder - this utility is used for encrypting passwords and contains the flawed encryption logic
    Affected if RVToolsPasswordEncryption.exe is present in the installation directory
  3. Identify stored encrypted passwords
    Search for configuration files, credential files, or password storage files in the RVTools user data directory (typically %APPDATA%\RVTools or within the installation folder) that contain encrypted password strings
    Affected if Any stored encrypted password entries exist on the system that were encrypted using the affected RVTools encryption utility
  4. Review password storage mechanism
    Examine any .xml, .config, or credential-related files in the RVTools directories for patterns indicating encrypted password storage (base64-encoded or otherwise obfuscated password fields)
    Affected if Encrypted passwords are stored in configuration or credential files accessible to other users or applications on the same system
  5. Assess access controls on RVTools files
    Check file permissions on the RVTools installation directory and user data folder - verify if non-privileged users or other accounts can read credential-related files
    Affected if File permissions allow unauthorized users to access stored encrypted passwords

You are affected if RVTools version is 3.9.2 or higher but below 4.5.0 AND you have stored encrypted passwords accessible on your system that were encrypted using the RVToolsPasswordEncryption.exe utility.

Upgrade available Upgrade to 4.5.0 or later
Fixed in 4.5.0
Interim mitigation

Immediately apply any vendor patches for RVTools when available, rotate all credentials that were stored using the affected encryption utility, and review systems for unauthorized access given the exposure of stored passwords.

Recommended fix High confidence

RVTools 4.5.0

  1. Download RVTools version 4.5.0 or later from the official Dell website or RVTools distribution channel
  2. Backup any existing RVTools installations and exported data containing encrypted passwords
  3. Install RVTools version 4.5.0 to replace the vulnerable version
  4. Verify the new version is running correctly by checking the application and encryption utility
  5. Re-encrypt any stored passwords using the updated RVToolsPasswordEncryption.exe utility to ensure they use the improved encryption
