Easy File Sharing HTTP Server 7.2 Buffer Overflow via POST to /sendemail.ghp

Published Jul 10, 2025 · Updated Apr 7, 2026 · Assigned by VulnCheck

Vendor: EFS Software Product: Easy File Sharing HTTP Server

Description

A stack-based buffer overflow vulnerability exists in Easy File Sharing HTTP Server version 7.2. The flaw is triggered when a crafted POST request is sent to the /sendemail.ghp endpoint containing an overly long Email parameter. The application fails to properly validate the length of this field, resulting in a memory corruption condition. An unauthenticated remote attacker can exploit this to execute arbitrary code with the privileges of the server process.
