This weakness leads to constant problems with a dereference of NULL pointer used by applications for elements expansion. NULL pointer can face many deteriorations: slowing down of work or ordinary programming errors.
Usually the processes performed with the help of NULL pointer end up with a failure and are almost impossible to carry out again. It's difficult to recover the software security even after checking the system and troubleshooting. Attackers can easily cause code or command execution.
The weakness is introduced during Implementation stage.
