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) character during variable substitution by modsql.

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 (modsqlpostgres) for ProFTPD before 1.2.9rc1 allows remote attackers to execute arbitrary SQL and gain privileges by bypassing authentication or stealing passwords via the USER name.

ProFTPd 1.2 compiled with the modsqlpw 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. via the last command.

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. palmetto.

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 vdproftpd.pm, a "ProFTPD remote exploit."

Buffer overflow in the tlsx509nameoneline function in the modtls 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 argument, a different vulnerability than CVE-2006-5815.

DISPUTED 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. NOTE: in November 2006, the role of CommandBufferSize was originally associated with CVE-2006-5815, but this was an error stemming from a vague initial disclosure. NOTE: ProFTPD developers dispute this issue, saying that the relevant memory location is overwritten by assignment before further use within the affected function, so this is not a vulnerability.

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

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 characters, as demonstrated using an ls command with multiple (1) "/..", (2) "/.", or (3) "../?/" sequences in the argument.

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 be logged.

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).

modsqlpw 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.

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.

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.

Off-by-one buffer overflow in xlateasciiwrite() in ProFTPD 1.2.7 through 1.2.9rc2p allows local users to gain privileges via a 1024 byte RETR command.

Buffer overflow in modradius 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.

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 SQLShowInfo modsql directive.

"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 authentication data, which might allow remote attackers to bypass authentication, as demonstrated by use of SQLAuthTypes Plaintext in modsql, with data retrieved from /etc/passwd."
