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.
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
