Synopsis

The remote FTP server is affected by an Memory Escape vulnerability.

Description

According to its banner, the installed version of Serv-U is a version prior to 15.2.3 Hotfix 2. It is, therefore, affected memory escape vulnerability. An unauthenticated remote attacker who successfully exploited this vulnerability could run arbitrary code with privileges, which could then install programs; view, change, or delete data; or run programs on the affected system.

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