Vulnerabilities

ProFTPD through 1.3.9e and 1.3.10rc1 through 1.3.10rc4 contains a link-following vulnerability in mod_copy that allows authenticated FTP users to bypass Limit WRITE restrictions via symlinks.

ProFTPD before 1.3.9e and 1.3.10rc5 contains an authorization bypass in the mod_sftp copy-file extension handler that skips Limit WRITE checks for new destination files.

ProFTPD before 1.3.9e and 1.3.10rc5 contains a buffer overflow vulnerability in the mod_rewrite int:utf8trans RewriteMap that allows remote attackers to overwrite static buffers.

ProFTPD mod_sftp contains a heap-based buffer overflow reachable by an authenticated SFTP user.

ProFTPD through 1.3.9b and 1.3.10rc2 contains an access control bypass vulnerability that allows authenticated FTP users to circumvent Directory ACL restrictions by prefixing paths with /proc/self/root in the RNFR comman…

A malicious backdoor was embedded in the official ProFTPD 1.3.3c source tarball distributed between November 28 and December 2, 2010.

SQL injection vulnerability in ProFTPD Server 1.3.1 through 1.3.2rc2 allows remote attackers to execute arbitrary SQL commands via a "%" (percent) character in the username, which introduces a "'" (single quote) characte…

ProFTPD 1.3.1 interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI…

The Auth API in ProFTPD before 20070417, when multiple simultaneous authentication modules are configured, does not require that the module that checks authentication is the same as the module that retrieves authenticati…

Buffer overflow in mod_radius in ProFTPD before 1.3.0rc2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password.

Stack-based buffer overflow in the pr_ctrls_recv_request function in ctrls.c in the mod_ctrls module in ProFTPD before 1.3.1rc1 allows local users to execute arbitrary code via a large reqarglen length value.

ProFTPD 1.3.0a and earlier does not properly set the buffer size limit when CommandBufferSize is specified in the configuration file, which leads to an off-by-two buffer underflow.

Buffer overflow in the tls_x509_name_oneline function in the mod_tls module, as used in ProFTPD 1.3.0a and earlier, and possibly other products, allows remote attackers to execute arbitrary code via a large data length a…

Stack-based buffer overflow in the sreplace function in ProFTPD 1.3.0 and earlier allows remote attackers, probably authenticated, to cause a denial of service and execute arbitrary code, as demonstrated by vd_proftpd.pm…

Multiple format string vulnerabilities in ProFTPD before 1.3.0rc2 allow attackers to cause a denial of service or obtain sensitive information via (1) certain inputs to the shutdown message from ftpshut, or (2) the SQLSh…

The glob functionality in ProFTPD 1.2.1, and possibly other versions allows remote attackers to cause a denial of service (CPU and memory consumption) via commands with large numbers of wildcard and other special charact…

ProFTPD 1.2.2rc2, and possibly other versions, does not properly verify reverse-resolved hostnames by performing forward resolution, which allows remote attackers to bypass ACLs or cause an incorrect client hostname to b…

ProFTPD 1.2.9 treats the Allow and Deny directives for CIDR based ACL entries as if they were AllowAll, which could allow FTP clients to bypass intended access restrictions.

ProFTPD 1.2.7 through 1.2.9rc2 does not properly translate newline characters when transferring files in ASCII mode, which allows remote attackers to execute arbitrary code via a buffer overflow using certain files.

SQL injection vulnerability in the PostgreSQL authentication module (mod_sql_postgres) for ProFTPD before 1.2.9rc1 allows remote attackers to execute arbitrary SQL and gain privileges by bypassing authentication or steal…

ProFTPd 1.2 compiled with the mod_sqlpw module records user passwords in the wtmp log file, which allows local users to obtain the passwords and gain privileges by reading wtmp, e.g.

Format string vulnerability in ProFTPD 1.2.0rc2 may allow attackers to execute arbitrary commands by shutting down the FTP server while using a malformed working directory (cwd).

mod_sqlpw module in ProFTPD does not reset a cached password when a user uses the "user" command to change accounts, which allows authenticated attackers to gain privileges of other users.

Buffer overflow in ProFTPD, wu-ftpd, and beroftpd allows remote attackers to gain root access via a series of MKD and CWD commands that create nested directories.

Buffer overflows in wuarchive ftpd (wu-ftpd) and ProFTPD lead to remote root access, a.k.a.
