CVE-2023-48795 42 Apache, Apple, Asyncssh Project and 39 more 68 Sshd, Sshj, Macos and 65 more 2024-03-13 N/A 5.9 MEDIUM
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

CVE-2004-1602 1 Proftpd 1 Proftpd 2024-02-15 5.0 MEDIUM N/A
ProFTPD 1.2.x, including 1.2.8 and 1.2.10, responds in a different amount of time when a given username exists, which allows remote attackers to identify valid usernames by timing the server response.
CVE-2004-0346 1 Proftpd 1 Proftpd 2024-02-02 7.2 HIGH 7.8 HIGH
Off-by-one buffer overflow in _xlate_ascii_write() in ProFTPD 1.2.7 through 1.2.9rc2p allows local users to gain privileges via a 1024 byte RETR command.
CVE-2001-0136 4 Conectiva, Debian, Mandrakesoft and 1 more 4 Linux, Debian Linux, Mandrake Linux and 1 more 2024-01-26 5.0 MEDIUM N/A
Memory leak in ProFTPd 1.2.0rc2 allows remote attackers to cause a denial of service via a series of USER commands, and possibly SIZE commands if the server has been improperly installed.
CVE-2023-51713 1 Proftpd 1 Proftpd 2024-01-08 N/A 7.5 HIGH
make_ftp_cmd in main.c in ProFTPD before 1.3.8a has a one-byte out-of-bounds read, and daemon crash, because of mishandling of quote/backslash semantics.
CVE-2021-46854 1 Proftpd 1 Proftpd 2023-12-10 N/A 7.5 HIGH
mod_radius in ProFTPD before 1.3.7c allows memory disclosure to RADIUS servers because it copies blocks of 16 characters.
CVE-2019-19270 2 Fedoraproject, Proftpd 2 Fedora, Proftpd 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. Failure to check for the appropriate field of a CRL entry (checking twice for subject, rather than once for subject and once for issuer) prevents some valid CRLs from being taken into account, and can allow clients whose certificates have been revoked to proceed with a connection to the server.
CVE-2020-9273 5 Debian, Fedoraproject, Opensuse and 2 more 9 Debian Linux, Fedora, Backports Sle and 6 more 2023-12-10 9.0 HIGH 8.8 HIGH
In ProFTPD 1.3.7, it is possible to corrupt the memory pool by interrupting the data transfer channel. This triggers a use-after-free in alloc_pool in pool.c, and possible remote code execution.
CVE-2019-18217 1 Proftpd 1 Proftpd 2023-12-10 5.0 MEDIUM 7.5 HIGH
ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.
CVE-2019-19272 1 Proftpd 1 Proftpd 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. Direct dereference of a NULL pointer (a variable initialized to NULL) leads to a crash when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.
CVE-2020-9272 3 Opensuse, Proftpd, Siemens 7 Backports Sle, Leap, Proftpd and 4 more 2023-12-10 5.0 MEDIUM 7.5 HIGH
ProFTPD 1.3.7 has an out-of-bounds (OOB) read vulnerability in mod_cap via the cap_text.c cap_to_text function.
CVE-2019-19271 1 Proftpd 1 Proftpd 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. A wrong iteration variable, used when checking a client certificate against CRL entries (installed by a system administrator), can cause some CRL entries to be ignored, and can allow clients whose certificates have been revoked to proceed with a connection to the server.
CVE-2019-19269 3 Debian, Fedoraproject, Proftpd 3 Debian Linux, Fedora, Proftpd 2023-12-10 4.0 MEDIUM 4.9 MEDIUM
An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. A dereference of a NULL pointer may occur. This pointer is returned by the OpenSSL sk_X509_REVOKED_value() function when encountering an empty CRL installed by a system administrator. The dereference occurs when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.
CVE-2019-12815 4 Debian, Fedoraproject, Proftpd and 1 more 5 Debian Linux, Fedora, Proftpd and 2 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
An arbitrary file copy vulnerability in mod_copy in ProFTPD up to 1.3.5b allows for remote code execution and information disclosure without authentication, a related issue to CVE-2015-3306.
CVE-2017-7418 1 Proftpd 1 Proftpd 2023-12-10 2.1 LOW 5.5 MEDIUM
ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user.
CVE-2016-3125 3 Fedoraproject, Opensuse, Proftpd 3 Fedora, Opensuse, Proftpd 2023-12-10 5.0 MEDIUM 7.5 HIGH
The mod_tls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman (DH) key to be used and consequently allow attackers to have unspecified impact via unknown vectors.
CVE-2015-3306 1 Proftpd 1 Proftpd 2023-12-10 10.0 HIGH N/A
The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.
CVE-2012-6095 1 Proftpd 1 Proftpd 2023-12-10 1.2 LOW N/A
ProFTPD before 1.3.5rc1, when using the UserOwner directive, allows local users to modify the ownership of arbitrary files via a race condition and a symlink attack on the (1) MKD or (2) XMKD commands.
CVE-2013-4359 1 Proftpd 1 Proftpd 2023-12-10 5.0 MEDIUM N/A
Integer overflow in kbdint.c in mod_sftp in ProFTPD 1.3.4d and 1.3.5r3 allows remote attackers to cause a denial of service (memory consumption) via a large response count value in an authentication request, which triggers a large memory allocation.
CVE-2010-3867 1 Proftpd 1 Proftpd 2023-12-10 7.1 HIGH N/A
Multiple directory traversal vulnerabilities in the mod_site_misc module in ProFTPD before 1.3.3c allow remote authenticated users to create directories, delete directories, create symlinks, and modify file timestamps via directory traversal sequences in a (1) SITE MKDIR, (2) SITE RMDIR, (3) SITE SYMLINK, or (4) SITE UTIME command.
