Description
The ACEManager
component of ALEOS 4.16 and earlier does not
perform input
sanitization during authentication, which could
potentially result
in a Denial of Service (DoS) condition for
ACEManager without
impairing other router functions. ACEManager
recovers from the
DoS condition by restarting within ten seconds of
becoming
unavailable.
