| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2010-20103 | A malicious backdoor was embedded in the official ProFTPD 1.3.3c source tarball distributed between November 28 and December 2, 2010. The backdoor implements a hidden FTP command trigger that, when invoked, causes the server to execute arbitrary shell commands with root privileges. This allows remote, unauthenticated attackers to run any OS command on the FTP server host. | [email protected] | 9.3 | 85.08% | 2025-08-20 | 2025-09-24 |
| CVE-2023-51713 | 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. | [email protected] | 7.5 | 70.30% | 2023-12-22 | 2025-11-03 |
| CVE-2023-48795 | 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 ha | [email protected] | 5.9 | 54.21% | 2023-12-18 | 2026-05-12 |
| CVE-2021-46854 | mod_radius in ProFTPD before 1.3.7c allows memory disclosure to RADIUS servers because it copies blocks of 16 characters. | [email protected] | 7.5 | 1.79% | 2022-11-23 | 2025-04-28 |
| CVE-2020-9273 | 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. | [email protected] | 8.8 | 60.22% | 2020-02-20 | 2024-11-21 |
| CVE-2020-9272 | ProFTPD 1.3.7 has an out-of-bounds (OOB) read vulnerability in mod_cap via the cap_text.c cap_to_text function. | [email protected] | 7.5 | 0.43% | 2020-02-20 | 2024-11-21 |
| CVE-2019-19269 | 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. | [email protected] | 4.9 | 1.03% | 2019-11-30 | 2024-11-21 |
| CVE-2019-19272 | 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. | [email protected] | 7.5 | 0.26% | 2019-11-26 | 2024-11-21 |
| CVE-2019-19271 | 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. | [email protected] | 7.5 | 0.66% | 2019-11-26 | 2024-11-21 |
| CVE-2019-19270 | 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. | [email protected] | 7.5 | 0.20% | 2019-11-26 | 2024-11-21 |
| CVE-2019-18217 | 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. | [email protected] | 7.5 | 3.31% | 2019-10-21 | 2024-11-21 |
| CVE-2019-12815 | 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. | [email protected] | 9.8 | 78.51% | 2019-07-19 | 2025-11-04 |
| CVE-2017-7418 | 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 pr | [email protected] | 5.5 | 0.04% | 2017-04-04 | 2026-05-13 |
| CVE-2016-3125 | 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. | [email protected] | 7.5 | 1.37% | 2016-04-05 | 2026-05-06 |
| CVE-2015-3306 | 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. | [email protected] | 10.0 | 93.68% | 2015-05-18 | 2026-05-06 |
| CVE-2013-4359 | 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. | [email protected] | 5.0 | 1.40% | 2013-09-30 | 2026-04-29 |
| CVE-2012-6095 | 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. | [email protected] | 1.2 | 0.06% | 2013-01-24 | 2026-04-29 |
| CVE-2011-4130 | Use-after-free vulnerability in the Response API in ProFTPD before 1.3.3g allows remote authenticated users to execute arbitrary code via vectors involving an error that occurs after an FTP data transfer. | [email protected] | 9.0 | 1.29% | 2011-12-06 | 2026-04-29 |
| CVE-2011-1137 | Integer overflow in the mod_sftp (aka SFTP) module in ProFTPD 1.3.3d and earlier allows remote attackers to cause a denial of service (memory consumption leading to OOM kill) via a malformed SSH message. | [email protected] | 5.0 | 3.45% | 2011-03-11 | 2026-04-29 |
| CVE-2010-4652 | Heap-based buffer overflow in the sql_prepare_where function (contrib/mod_sql.c) in ProFTPD before 1.3.3d, when mod_sql is enabled, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted username containing substitution tags, which are not properly handled during construction of an SQL query. | [email protected] | 6.8 | 6.04% | 2011-02-02 | 2026-04-29 |
