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
Proself Enterprise/Standard Edition Ver5.61 and earlier, Proself Gateway Edition Ver1.62 and earlier, and Proself Mail Sanitize Edition Ver1.07 and earlier allow a remote authenticated attacker with an administrative privilege to execute arbitrary OS commands.

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

OS command injection vulnerability in Proself file management software (Enterprise/Standard, Gateway, and Mail Sanitize editions). An authenticated attacker with administrative privileges can execute arbitrary operating system commands on the host system.

MitigationApply vendor patches: upgrade to Proself Enterprise/Standard Ver5.62+, Gateway Ver1.63+, or Mail Sanitize Ver1.08+. Until patched, strictly limit administrative access to trusted users and implement network segmentation.

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. Identify Proself installation
    Check for Proself file management software by looking for installation directories (commonly under /opt/proself, C:\Program Files\Proself, or the application's web root). Look for proself-related processes or services running on the system.
    Affected if Proself software is installed on the system
  2. Determine installed version
    Locate and read the version information file or check the admin web interface for the software version. This is typically displayed in the administration panel or in a version/info file within the installation directory.
    Affected if The installed version cannot be determined or is <= 1.07, <= 1.62, or <= 5.61 for Enterprise/Standard editions; or similarly vulnerable versions for Gateway and Mail Sanitize editions
  3. Confirm edition type
    Identify which Proself edition is installed: Enterprise/Standard, Gateway, or Mail Sanitize. This is usually visible in the product name, license information, or admin interface.
    Affected if The edition is Enterprise/Standard, Gateway, or Mail Sanitize and the version falls within the affected ranges
  4. Check administrative access exposure
    Determine if the Proself administrative interface (typically /proself/admin or similar) is accessible from the network. Review firewall rules and web server configuration for the admin endpoint.
    Affected if The administrative interface is exposed to untrusted networks or users
  5. Verify administrative accounts
    Review the list of users granted administrative privileges in Proself. Check user management configuration or directory to enumerate accounts with admin roles.
    Affected if There are administrative accounts beyond the intended trusted administrators

You are affected if Proself Enterprise/Standard (versions <= 1.07, <= 1.62, or <= 5.61), Gateway, or Mail Sanitize is installed and the administrative interface is accessible to untrusted authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 5.61
Interim mitigation

Apply vendor patches: upgrade to Proself Enterprise/Standard Ver5.62+, Gateway Ver1.63+, or Mail Sanitize Ver1.08+. Until patched, strictly limit administrative access to trusted users and implement network segmentation.
