CVE-2024-6744
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 · uneditedThe SMTP Listener of Secure Email Gateway from Cellopoint does not properly validate user input, leading to a Buffer Overflow vulnerability. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary system commands on the remote server.
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 confidenceThe SMTP Listener component in Cellopoint Secure Email Gateway fails to validate user input properly, allowing a buffer overflow condition. An unauthenticated remote attacker can exploit this to execute arbitrary system commands on the affected server with elevated privileges.

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.
-
Identify Cellopoint Secure Email Gateway installationLocate the product installation directory or check system services for Cellopoint Secure Email Gateway componentsAffected if The product is installed on the system
-
Determine the installed versionUse the product's admin interface, version check command, or examine version files to identify the current version numberAffected if The installed version is lower than 4.5.0
-
Verify SMTP Listener component is enabledCheck the product configuration to confirm the SMTP Listener service or module is active and runningAffected if SMTP Listener is enabled and operational
-
Assess SMTP network exposureReview firewall rules, network configuration, or access control lists to determine if SMTP ports are accessible from untrusted or external networks without authentication restrictionsAffected if SMTP is accessible to unauthenticated remote attackers from untrusted networks
The environment is affected if Cellopoint Secure Email Gateway is installed with a version lower than 4.5.0 and the SMTP Listener component is exposed to unauthenticated network access.

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.
dbcve · scoped4.5.0
Apply vendor-provided security patches for Secure Email Gateway immediately. If no patch is available, restrict or block unauthenticated SMTP access from untrusted networks using firewall or network segmentation as an interim control.
4.5.0
- Backup the current Secure Email Gateway configuration and any critical data
- Obtain the fixed version 4.5.0 from the official Cellopoint vendor or authorized distribution channel
- Review Cellopoint upgrade documentation for the specific upgrade procedure for your deployment model
- Apply the upgrade to the Secure Email Gateway instance
- After upgrading, verify the SMTP Listener service is running correctly
- Confirm the version has been updated to 4.5.0 by checking the system information or about page
- Test SMTP functionality (receiving and processing emails) to ensure normal operation
