CVE-2026-119568 1 Vsftpd Project 1 Vsftpd 2026-10-30 7.4 High
vsftpd through 3.0.5 contains an authentication bypass vulnerability in ssl_data_accept() that allows unauthenticated attackers to hijack FTPS data connections by resuming their own TLS session ticket. Attackers sharing the victim's source IP can obtain a ticket via AUTH TLS, then connect to the victim's PASV port to steal downloads or inject upload data.
CVE-2026-119567 1 Vsftpd Project 1 Vsftpd 2026-10-30 3.1 Low
vsftpd through 3.0.5 contains an access control bypass vulnerability that allows authenticated FTP users to execute denied commands by issuing RFC 775 X-prefixed aliases. The cmds_denied check in process_post_login() compares literal tokens, so attackers can send XRMD, XMKD, XCWD, XPWD, or XCUP to perform blocked operations like deleting directories.
CVE-2015-1419 2 Opensuse, Vsftpd Project 2 Opensuse, Vsftpd 2025-04-12 N/A
Unspecified vulnerability in vsftpd 3.0.2 and earlier allows remote attackers to bypass access restrictions via unknown vectors, related to deny_file parsing.
CVE-2011-0762 7 Canonical, Debian, Fedoraproject and 4 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2025-04-11 N/A
The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632.
CVE-2021-3618 5 Debian, F5, Fedoraproject and 2 more 5 Debian Linux, Nginx, Fedora and 2 more 2024-11-21 7.4 High
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.
CVE-2021-30047 1 Vsftpd Project 1 Vsftpd 2024-11-21 7.5 High
VSFTPD 3.0.3 allows attackers to cause a denial of service due to limited number of connections allowed.
CVE-2011-2523 2 Debian, Vsftpd Project 2 Debian Linux, Vsftpd 2024-11-21 9.8 Critical
vsftpd 2.3.4 downloaded between 20110630 and 20110703 contains a backdoor which opens a shell on port 6200/tcp.
