Summary
This host is running a version of WS_FTP FTP server prior to 3.1.2.
Insight
Insight
Versions earlier than 3.1.2 contain an unchecked buffer in routines that handle the 'CPWD' command arguments. The 'CPWD' command allows remote users to change their password. By issuing a malformed argument to the CPWD command, a user could overflow a buffer and execute arbitrary code on this host. Note that a local user account is required.
