Multiple external config control vulnerabilities exist in the nas.cgi setnas() proftpd functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to permission bypass. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A configuration injection vulnerability exists in the ftpmaxsessions POST parameter.
modradius in ProFTPD before 1.3.7c allows memory disclosure to RADIUS servers because it copies blocks of 16 characters.
An issue was discovered in tlsverifycrl in ProFTPD through 1.3.6b. A dereference of a NULL pointer may occur. This pointer is returned by the OpenSSL skX509REVOKEDvalue() 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.
An issue was discovered in tlsverifycrl 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once for issuer) prevents some valid CRLs from being taken into account, and can allow clients whose certificates have been revoked to proceed with a connection to the server.
An issue was discovered in tlsverifycrl 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by a system administrator), can cause some CRL entries to be ignored, and can allow clients whose certificates have been revoked to proceed with a connection to the server.
An issue was discovered in tlsverifycrl 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.
An arbitrary file copy vulnerability in modcopy in ProFTPD up to 1.3.5b allows for remote code execution and information disclosure without authentication, a related issue to CVE-2015-3306.
The modtls 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.
Integer overflow in kbdint.c in modsftp 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.
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.
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.
An integer overflow flaw was reported [1],[2] in the modsftp module of ProFTPD. If a specially crafted SSH message was sent to a ProFTPD server using modsftp, it could lead to the allocation of enormous amounts of memory and an eventual OOM termination by the kernel. This issue was assigned the name CVE-2011-1137 [3]. It was fixed in CVS [4],[5],[6]

The prdataxfer function in ProFTPD before 1.3.2rc3 allows remote authenticated users to cause a denial of service (CPU consumption) via an ABOR command during a data transfer.
modtls.c in ProFTPD 1.3.2a does not properly handle a '\0' character in a domain name in the subject's alternative name (subjectAltName) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

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 that leverages an existing session from the FTP client implementation in a web browser.
