Vulnerabilities

Core FTP 2.0 build 653 contains a denial of service vulnerability in the PBSZ command that allows unauthenticated attackers to crash the service by sending a malformed command with an oversized buffer. Attackers can send a PBSZ command with a payload exceeding 211 bytes to trigger an access violation and crash the FTP server process.

Core FTP/SFTP Server 1.2 contains a buffer overflow vulnerability that allows attackers to crash the service by supplying an excessively long string in the User domain field. Attackers can paste a malicious payload containing 7000 bytes of data into the domain configuration to trigger an application crash and deny service.

Core FTP / SFTP Server v2 Build 725 was discovered to allow unauthenticated attackers to cause a Denial of Service (DoS) via a crafted packet through the SSH service.

CoreFTP Server before 727 allows directory traversal (for file creation) by an authenticated attacker via ../ in an HTTP PUT request.

Buffer overflow vulnerability in Core FTP Server v1.2 Build 583, via a crafted username.

Buffer overflow in Core FTP LE v2.2 allows local attackers to cause a denial or service (crash) via a long string in the Setup->Users->Username editbox.

An issue was discovered in the SFTP Server component in Core FTP 2.0 Build 674. Using the MDTM FTP command, a remote attacker can use a directory traversal technique (..\..\) to browse outside the root directory to determine the existence of a file on the operating system, and its last modified date.

The server in Core FTP 2.0 build 653 on 32-bit platforms allows remote attackers to cause a denial of service (daemon crash) via a crafted XRMD command.

Core FTP LE version 2.2 Build 1921 is prone to a buffer overflow vulnerability that may result in a DoS or remote code execution via a PASV response.
