Vulnerabilidades

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…

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…

Core FTP Lite 1.3 contains a buffer overflow vulnerability in the username input field that allows attackers to crash the application by supplying oversized input. Attackers can generate a 7000-byte payload of repeated 'A' characters to trigger an application crash without requiring additional interaction.

Core FTP LE 2.2 contains a denial of service vulnerability that allows attackers to crash the application by overwriting the account field with a large buffer. Attackers can create a text file with 20,000 repeated characters and paste it into the account field to cause the application to become unresponsive and…

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 vulnerability in Core FTP Server v2 Build 697, 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.

An issue was discovered in the SFTP Server component in Core FTP 2.0 Build 674. A directory traversal vulnerability exists using the SIZE command along with a \..\..\ substring, allowing an attacker to enumerate file existence based on the returned information.

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.

Multiple buffer overflows in Core FTP Server before 1.2 build 508 allow local users to gain privileges via vectors related to reading data from config.dat and Windows Registry.

Multiple heap-based buffer overflows in the client in Core FTP LE 2.2 build 1798 allow remote FTP servers to cause a denial of service (application crash) and possibly execute arbitrary code via a long string in a reply to a (1) USER, (2) PASS, (3) PASV, (4) SYST, (5) PWD, or (6) CDUP command.

Core FTP Server 1.2 before build 515 allows remote authenticated users to obtain sensitive information (password for the previous user) via a USER command with a specific length, possibly related to an out-of-bounds read.

Directory traversal vulnerability in Core FTP Server 1.2 before build 515 allows remote authenticated users to determine the existence of arbitrary files via a /../ sequence in an XCRC command.

Core FTP Server 1.2 before build 515 allows remote attackers to cause a denial of service (reachable assertion and crash) via an AUTH SSL command with malformed data, as demonstrated by pressing the enter key twice.

Stack-based buffer overflow in Core FTP before 2.2 build 1785 allows remote FTP servers to execute arbitrary code via a crafted directory name in a CWD command reply.

Stack-based buffer overflow in Core FTP 2.1 build 1612 allows user-assisted remote attackers to execute arbitrary code via a long hostname in an FTP server entry in a site backup file. NOTE: some of these details are obtained from third party information.

Directory traversal vulnerability in Core FTP client 2.1 Build 1565 allows remote FTP servers to create or overwrite arbitrary files via .. (dot dot) sequences in responses to LIST commands, a related issue to CVE-2002-1345. NOTE: this can be leveraged for code execution by writing to a Startup folder.
