CVE-2025-5595
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 · uneditedA vulnerability was found in FreeFloat FTP Server 1.0 and classified as critical. This issue affects some unknown processing of the component PROGRESS Command Handler. The manipulation leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
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 confidenceA buffer overflow vulnerability in the PROGRESS command handler of FreeFloat FTP Server 1.0 allows remote attackers to execute arbitrary code by sending specially crafted input to the FTP server. The vulnerability is exploitable without authentication and has a public exploit.

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 if FreeFloat FTP Server is runningCheck running processes or services on the system for FreeFloat FTP Server executableAffected if FreeFloat FTP Server process is actively running on the system
-
Confirm the installed version is 1.0Locate the FreeFloat FTP Server installation and verify the exact version number equals 1.0Affected if The installed version is FreeFloat FTP Server 1.0 exactly
-
Verify FTP service is accessibleCheck if the FTP port (default 21) is listening and accessible on the network or locallyAffected if FTP service is exposed and accepting connections
-
Confirm PROGRESS command handling is enabledThe PROGRESS command is a built-in handler in FreeFloat FTP Server 1.0 - if the server is running, this command is available by defaultAffected if The server is running and processing FTP commands
If FreeFloat FTP Server version 1.0 is running and accessible, the environment is affected by this vulnerability.

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 · scopedReplace FreeFloat FTP Server with a currently-supported FTP server solution, as FreeFloat is outdated and likely unpatched. If replacement is not immediately feasible, isolate the server behind a firewall and restrict access to trusted IP addresses only.
- Freefloat FTP Server 1.0 is abandoned software with no vendor support, no patches, and no fixed versions available.
- Assess the criticality of the FTP service and determine if it can be decommissioned or replaced with a actively maintained FTP server implementation.
- If the FTP service must continue operating, implement strict network-level mitigations: place the server in a highly restricted network segment with firewall rules permitting only explicitly required access.
- Disable the PROGRESS command if possible at the firewall or network level to block the attack vector.
- Monitor for indicators of compromise given the public exploit disclosure.
