CrushFTP, LLC Company Cyber Security Posture
crushftp.comPut simply, CrushFTP is a secure high speed file transfer server that runs on almost any OS. It handles a wide array of protocols, and security options. It gives the server administrator the ability to customize, monitor, and control every aspect of the serverโs operations. CrushFTP is stand alone and self contained. It doesnโt run on top of another vendorsโ server code, or rely on another vendors application container. The HTTP server isnโt based on Tomcat, or others. This means that when vulnerabilities are discovered for Tomcat, you donโt have to go run and patch your server to keep it secure. CrushFTP maintains its own security stack, which is comprised of industry standard, enterprise-grade technologies. This also means that the protocol engines are designed from the ground up for file transfer. Itโs not an after thought where you have to see if the engine in the product can handle a large file, or protect against PHP exploits or other script vulnerabilities. CrushFTP does not run server side scripts as a web application server may do. CrushFTP specializes in file transfer, and does it very well. The HTTP engine in CrushFTP understands when a large file is being uploaded and avoids checking every incoming byte to look for the โend of fileโ signature that web browsers send. It knows it doesnโt need to check for this until the file transfer is almost done. This saves on CPU usage considerably, and allows for faster transfers.

CrushFTP | Vulnerability | 25 | 1 | 7/2025 | CRU709072025 | Link | |
Rankiteo Explanation : Attack without any consequencesDescription: CrushFTP is warning about a zero-day vulnerability (CVE-2025-54309) that allows attackers to gain administrative access via the web interface on vulnerable servers. The vulnerability was first detected on July 18th, but it may have been exploited earlier. A prior fix inadvertently blocked this vulnerability, but threat actors reverse-engineered the software and began exploiting it on unpatched systems. Systems kept up to date are not vulnerable. Indicators of compromise include unexpected entries in user.XML and new, unrecognized admin-level usernames. It is unclear if the attacks were used for data theft or to deploy malware, but similar platforms have been targeted by ransomware gangs for mass data theft and extortion attacks. |
