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
In Versa Director, the unencrypted backup files stored on the Versa deployment contain credentials stored within configuration files. These credentials are for various application components such as SNMP, and SSL and Trust keystores.

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 · high confidence

Versa Director stores backup files without encryption, and these backups contain configuration files that expose credentials for SNMP, SSL, and Trust keystores. An attacker with access to these unencrypted backup files could extract sensitive credentials for lateral movement or further compromise.

MitigationEnable encryption for Versa Director backup files and rotate all credentials that were stored in unencrypted backups (SNMP, SSL, Trust keystores). Implement secure backup storage policies.

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. Confirm Versa Director is deployed
    Identify whether Versa Director software is running or installed in the environment. Check for processes or services named 'versa-director' or related components.
    Affected if Versa Director is present in the environment
  2. Locate backup files
    Find backup files created by Versa Director. Check common backup storage locations such as /backup, /var/versa/backups, or the configured backup path in Versa Director configuration.
    Affected if One or more Versa Director backup files exist
  3. Inspect backup file encryption
    Examine a recent backup file to determine if it is encrypted. Check for signs of encryption such as encrypted file headers, lack of plaintext content, or specific encryption indicators. Compare encrypted vs unencrypted backup file signatures.
    Affected if Backup files are stored without encryption (plaintext or uncompressed)
  4. Extract and inspect backup contents
    If the backup is unencrypted, extract its contents and search for configuration files that store credentials. Look for files related to SNMP configuration, SSL certificates, and Trust keystores.
    Affected if The backup contains configuration files with SNMP, SSL, or Trust keystore credentials
  5. Verify credential exposure
    Open the credential-containing configuration files found in the backup and confirm whether sensitive credentials (passwords, keys, certificates) are stored in plaintext or are readable without decryption.
    Affected if Credentials are stored in plaintext and readable without decryption

If Versa Director backup files exist and are stored without encryption, the environment is affected by this vulnerability.
