Security readout for executives and security teams
Plain-English summary
EasyFTP Server 1.7.0.11 and earlier has a critical flaw in its built-in web interface. A specially long path value to list.html can crash or potentially take over the service without login, because anonymous access is enabled by default. Treat any internet-accessible instance as urgent until upgraded or removed.
Executive priority
Prioritize within the next remediation cycle, faster for internet-facing systems. The combination of unauthenticated network reachability, critical impact, and public exploit references creates high operational risk despite no cited active exploitation evidence.
Technical view
This is a CWE-121 stack-based buffer overflow in HTTP GET handling for the list.html path parameter. The bundle reports network, low-complexity, unauthenticated exposure with high confidentiality, integrity, and availability impact, CVSS 4.0 score 9.3. It was resolved in version 1.7.0.12, after which the product was renamed UplusFtp.
Likely exposure
Exposure is limited to organizations still running KMiNT21 EasyFTP Server 1.7.0.11 or earlier, especially where the embedded web server is reachable from untrusted networks. The affected-version metadata in the bundle is inconsistent, so validate installed versions directly.
Exploitation context
The bundle cites public exploit references in Metasploit and Exploit-DB, which indicates practical exploit knowledge is public. It does not cite CISA KEV listing or active exploitation evidence, so active exploitation should not be claimed from these sources alone.
Researcher notes
Focus validation on product/version confirmation and exposed HTTP management surface. Avoid assuming broad product impact beyond EasyFTP Server 1.7.0.11 and earlier. The provided affected metadata appears inconsistent with the narrative, so preserve source caveats in downstream tracking.
Mitigation direction
- Upgrade EasyFTP Server to version 1.7.0.12 or later vendor successor guidance.
- Remove unsupported EasyFTP Server instances where upgrade is not possible.
- Restrict embedded web server access to trusted management networks only.
- Disable anonymous access if vendor-supported and operationally feasible.
- Monitor vendor or successor product advisories for additional guidance.
Validation and detection
- Inventory hosts for EasyFTP Server or UplusFtp installations.
- Confirm installed versions are not 1.7.0.11 or earlier.
- Check whether the embedded HTTP interface is reachable externally.
- Review logs for unusual list.html requests or service crashes.
- Verify compensating network controls block untrusted access.

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
