CVE-2024-25501
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 · uneditedAn issue WinMail v.7.1 and v.5.1 and before allows a remote attacker to execute arbitrary code via a crafted script to the email parameter.
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 confidenceWinMail versions 7.1, 5.1 and prior contain a code injection vulnerability in the email parameter handling. Remote attackers can submit a crafted script to the email parameter that results in arbitrary code execution on the server.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm WinMail installationCheck for WinMail processes running (winmail.exe, winmailserver.exe) or look for installation directories like C:\Program Files\WinMail\ or C:\WinMail\. On Windows, also check Services for a WinMail service entry.Affected if WinMail server software is present on the system
-
Identify installed versionCheck the version of the WinMail executable or service. Right-click the winmail.exe file in the installation directory, select Properties, and view the Version tab. Alternatively, access the WinMail admin interface and locate the version information typically shown in the About or System Info section.Affected if The version is 5.1 or lower, or 7.1 or lower (any version <= 5.1 or <= 7.1)
-
Verify webmail interface is accessibleDetermine if the WinMail webmail or administrative web interface is exposed to network access. Check for listening ports (commonly 6080, 8080, or 443) using netstat -an or by reviewing firewall rules. Try accessing the login page from a browser if you are on the network.Affected if The web-based email interface is network-accessible (this is the attack vector for remote exploitation)
-
Inspect email parameter handlingReview the WinMail server configuration or access logs for how the email parameter is processed. Check configuration files in the WinMail\server\ or WinMail\admin\ directories for email validation settings. Examine server logs for any evidence of script injection attempts in email fields.Affected if Email parameter input is accepted without sanitization or the configuration shows no input validation on email fields
You are affected if WinMail version 5.1 or below, or 7.1 or below is installed AND the webmail interface is accessible, allowing remote submission of the email parameter.

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 dataImplement strict input validation and sanitization on the email parameter to reject or neutralize script injection attempts. Validate email format according to RFC standards and escape or remove any scriptable content before processing or storing.
