In Alinto SOPE SOGo 2.0.2 through 5.12.2, sope-core/NGExtensions/NGHashMap.m allows a NULL pointer dereference and SOGo crash via a request in which a parameter in the query string is a duplicate of a parameter in the POST body.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
