VAR-202001-1606
Vulnerability from variot - Updated: 2024-11-23 22:25In uftpd before 2.11, there is a buffer overflow vulnerability in handle_PORT in ftpcmd.c that is caused by a buffer that is 16 bytes large being filled via sprintf() with user input based on the format specifier string %d.%d.%d.%d. The 16 byte size is correct for valid IPv4 addresses (len('255.255.255.255') == 16), but the format specifier %d allows more than 3 digits. This has been fixed in version 2.11. uftpd Contains a classic buffer overflow vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state

CVE-2020-5221 (GCVE-0-2020-5221)
Vulnerability from nvd – Published: 2020-01-22 18:50 – Updated: 2024-08-04 08:22

Title
Directory Traversal (Chroot Escape) vulnerability in uftpd
Summary
In uftpd before 2.11, it is possible for an unauthenticated user to perform a directory traversal attack using multiple different FTP commands and read and write to arbitrary locations on the filesystem due to the lack of a well-written chroot jail in compose_abspath(). This has been fixed in version 2.11
Severity
6.5 (Medium)

Buffer overflow vulnerability in uftpd
Summary
In uftpd before 2.11, there is a buffer overflow vulnerability in handle_PORT in ftpcmd.c that is caused by a buffer that is 16 bytes large being filled via sprintf() with user input based on the format specifier string %d.%d.%d.%d. The 16 byte size is correct for valid IPv4 addresses (len('255.255.255.255') == 16), but the format specifier %d allows more than 3 digits. This has been fixed in version 2.11
Severity
6.5 (Medium)
CWE
- CWE-121 - Stack-based Buffer Overflow

Title
Directory Traversal (Chroot Escape) vulnerability in uftpd
Summary
In uftpd before 2.11, it is possible for an unauthenticated user to perform a directory traversal attack using multiple different FTP commands and read and write to arbitrary locations on the filesystem due to the lack of a well-written chroot jail in compose_abspath(). This has been fixed in version 2.11
Severity
6.5 (Medium)
CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Title
Buffer overflow vulnerability in uftpd
Summary
In uftpd before 2.11, there is a buffer overflow vulnerability in handle_PORT in ftpcmd.c that is caused by a buffer that is 16 bytes large being filled via sprintf() with user input based on the format specifier string %d.%d.%d.%d. The 16 byte size is correct for valid IPv4 addresses (len('255.255.255.255') == 16), but the format specifier %d allows more than 3 digits. This has been fixed in version 2.11
Severity
6.5 (Medium)
