A vulnerability in local FTP to the Cisco Email Security Appliance (ESA) could allow an
unauthenticated, remote attacker to cause a partial denial of service (DoS) condition when the FTP
application unexpectedly quits.
The vulnerability is due to improper input validation of user-supplied fields when logging in using
FTP. An attacker could exploit this vulnerability by opening an FTP connection to the targeted
device and crafting user-supplied parameters. An exploit could allow the attacker to cause a
partial DoS condition when the FTP process unexpectedly quits. This vulnerability does not impact
other user traffic.
Cisco has released software updates that address this vulnerability. There are no workarounds that
address this vulnerability.
