high Nessus Plugin ID 177841

Language:

Synopsis

The remote host has a FTP server installed that is affected by a denial of service vulnerability.

Description

The version of GlobalSCAPE EFT installed on the remote host is 8.0.x prior to 8.0.0.38. A denial of service (DoS) vulnerability exists due to improper handling of a recursively compressed packet. An unauthenticated, remote attacker can exploit this issue, via specially crafted packeet, to cause the process to stop responding.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to GlobalSCAPE EFT 8.1.0.16 or later.
