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
GFI MailEssentials AI versions prior to 22.4 contain a stored cross-site scripting vulnerability in the Sender Policy Framework IP Exceptions interface. An authenticated user can supply HTML/JavaScript in the ctl00$ContentPlaceHolder1$pv2$txtIPDescription parameter to /MailEssentials/pages/MailSecurity/SenderPolicyFramework.aspx, which is stored and later rendered in the management interface, allowing script execution in the context of a logged-in user.

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

Stored XSS vulnerability in GFI MailEssentials AI's Sender Policy Framework IP Exceptions interface allows authenticated users to inject malicious HTML/JavaScript via the txtIPDescription parameter. The payload is stored and executed when other users view the management interface.

MitigationUpgrade to version 22.4 or later; implement input validation and output encoding on the txtIPDescription parameter to prevent script execution.

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 GFI MailEssentials is installed
    Locate the GFI MailEssentials installation directory or check Add/Remove Programs for 'GFI MailEssentials' entry
    Affected if GFI MailEssentials is not present on the system, the vulnerability does not apply
  2. Identify installed version number
    Check the product version through the GFI MailEssentials UI (typically in Help > About) or examine the installed binaries for version metadata
    Affected if The installed version is any version prior to 22.4 (e.g., 22.3, 22.2, older releases)
  3. Verify SPF IP Exceptions feature is accessible
    Log into the GFI MailEssentials management interface and navigate to the Sender Policy Framework (SPF) section to confirm the IP Exceptions management interface exists and is accessible
    Affected if The SPF IP Exceptions interface is not present or not accessible in the deployment
  4. Check for existing XSS indicators in txtIPDescription field
    Review any existing entries in the SPF IP Exceptions list and inspect the txtIPDescription field values for suspicious characters or encoded scripts
    Affected if Malicious payloads or encoded script tags are found stored in the txtIPDescription field values

The environment is affected if GFI MailEssentials version is below 22.4 and the SPF IP Exceptions management interface is accessible to authenticated users.
