An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. An HTTP POST request with a specially crafted Host header field may cause a NULL pointer dereference and thus cause a denial of service, as demonstrated by the lack of a trailing ] character in an IPv6 address.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
