FileZilla Server before 0.9.22 allows remote attackers to cause a denial of service (crash) via a malformed argument to the STOR command, which results in a NULL pointer dereference. NOTE: CVE analysis suggests that the problem might be due to a malformed PORT command.

Security readout for executives and security teams

This is an old FileZilla Server availability issue. Versions before 0.9.22 can crash when a remote attacker sends malformed FTP command input. The impact is service interruption, not confirmed data theft or code execution in the provided sources. Exposure is likely limited to organizations still running FileZilla Server versions earlier than 0.9.22, especially if the FTP service is reachable by untrusted networks. Treat this as a legacy-service resilience issue. Prioritize externally exposed or business-critical FileZilla Server instances, but current evidence does not support emergency response absent vulnerable deployments. Mitigation focus: Upgrade FileZilla Server versions earlier than 0.9.22.; Check FileZilla release notes and vendor guidance for the applicable fixed release.; Restrict FTP access to trusted networks where possible..
