Gabriel Silva has discovered two vulnerabilities in acFTP, which can
be exploited by malicious users and malicious people to cause a DoS
(Denial of Service).
The vulnerabilities are caused due to input validation errors when
handling arguments passed to the REST and PBSZ commands. This can be
exploited to crash the service by passing a specially crafted string
as argument to either of the affected commands.
Successful exploitation using the REST command requires a valid user
account.
The vulnerabilities are confirmed in version 1.5. Other versions may
also be affected.
