CVE-2024-0736 is a medium severity flaw in EFS Easy File Sharing FTP Server 3.6, scored 5.3 by NVD. No fixed version is confirmed in the sources I could check, so limit who can reach it, watch for a vendor release, and plan an upgrade or replacement.
What's affected
The record lists EFS Easy File Sharing FTP Server 3.6 as affected. The record says the manipulation of the password argument in the Login component leads to denial of service and that the attack can be started remotely. The CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L. The weakness is CWE-404.
The record's description is short and does not name a fixed release. The linked pages are public write-ups of the issue, not a vendor patch notice.
How to check if you're exposed
Look for the Easy File Sharing FTP service in the Windows Services list or the installed programs list and read the version. Version 3.6 is named. Check whether the FTP port is open to networks beyond the one you intend, for example with netstat -ano.
If the product reached you inside another package, run the free in-browser dependency scan at gold.safeguard.sh/scan against your manifests to see whether it appears. For standalone software, the inventory is the check: find where it is installed, which version it is, and whether the service is reachable from outside the machine.
What to do now
- Find every installation of the product and note its version.
- Check the vendor site and project repository for a newer release, and read its notes before upgrading. Do not assume a later version is fixed without a statement that says so.
- Restrict network access to the service with firewall rules so only trusted hosts can reach it.
- Watch logs for repeated odd requests or unexpected crashes aimed at the affected component.
- If the software looks unmaintained, plan to replace it, and record the risk decision in the meantime.
Why it matters
A denial of service in a network service means a remote client can make it stop answering. Here the record ties it to input handled by the login or command processing path, and tags it with CWE-404 (improper resource shutdown or release), which describes resources not being released or handled properly. For a file transfer or remote login service, that can interrupt anyone who relies on it, and a crash on crafted input often points to weak input handling elsewhere in the same code.
The score is medium because only availability is affected: nothing in the record says data is read or changed. Still, these small servers are often run by a single person on a spare machine, with no failover, so an outage lasts until someone notices. When no patch exists, restricting who can reach the port is the practical control.
The record notes that an exploit has been disclosed publicly. That is not the same as confirmed attacks, and the record does not flag this CVE in the CISA Known Exploited Vulnerabilities list. Public detail still lowers the effort for someone to try it, which is a reason to reduce exposure early.
Quick check
How is this different from CVE-2024-0693?
Both hit Easy File Sharing FTP Server, but CVE-2024-0693 concerns version 2.0 and the username field, while this one concerns version 3.6 and the password field.
Do I need to log in first?
The record rates privileges required as none, and the flaw sits in the login component.
